problems creating read-only, 'consumer' dirsrv replica
by Jon Detert 16 Mar '11

16 Mar '11

Hello, I am trying to deploy an additional read-only replica (aka. 'consumer') in a single-master dirsrv environment. The master, and the other pre-existing consumer servers, are all 'fedora-ds' running on Fedora 7. I'm trying to add a consumer running on Centos 5.5. Ultimately, I intend to replace the Fedora ds servers with Centos dirsrv servers. I'm trying to deploy the Centos dirsrv consumer without running the dirsrv-admin. I've been following the directions at http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.1/html/Adminis… , specifically in chapter 8. When I get to "8.7.2. Configuring Consumers from the Command Line" ( http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.1/html/Adminis… ), I run into problems: 1) ldapmodify complains that I'm missing the required attribute 'nsds5replicaId'. So I add it, and guess at the replicaID number (cuz the guide says nothing about the ID). 2) even after resolving issue 1) above, I get an error: "ldap_add: No such object" The return value of the ldapmodify command is 32. The changetype of the operation is 'add', so ldapmodify knows it's trying to add an object. The input I pass to ldapmodify is just like shown in the guide, but w. the addition of the nsds5replicaId attribute mentioned in issue 1) above: dn: cn=replica,cn="dc=infinityhealthcare,dc=com",cn=mapping tree,cn=config changetype: add objectclass: top objectclass: nsds5replica objectclass: extensibleObject cn: replica nsds5replicaroot: dc=infinityhealthcare,dc=com nsds5replicatype: 2 nsDS5ReplicaId: 65535 nsds5ReplicaBindDN: uid=RManager,cn=config nsds5flags: 0 Any idea what's wrong? Do I have to first create dn: cn="dc=infinityhealthcare,dc=com",cn=mapping tree,cn=config ? If so, how? The guide doesn't seem to have a step for that, except for when adding a 'hub' dirsrv. However, I mean to add a 'consumer', not a 'hub'. Thanks, Jon

install specific version using yum

Swap space for kvm virtual host
by Nataraj 15 Mar '11

15 Mar '11

I have a kvm virtual host running on what will become CentOS 6 with 12GB of memory and a Quad Xeon X5560 2.8Ghz . The store for virtual machines will be a software raid 6 array of 6 disks with an LVM layered on top. I'm not initially planning any major overcommitment of resources, though there could be a need for some overcommitment with a light workload on the guests. In recent years people seem to configure a wide range of different swap allocations. I was thinking initially to spread swap across seperate non-raid partitions on 4 of these disks, but the downside of that is if I put 2gb on each disk, then I can only swap processes that will fit in 2gb swap space. Also, if one of the disks fails, I have to reboot if anything was swapped to that drive. My questions are as follows: 1. What experience are others having with putting swap space on raid partitions? I was thinking about maybe swapping on a raid10 device, otherwise an LVM spanning multiple drives. 2. In practice, what kinds of swap allocation are people finding useful for a kvm virtual host of this size? I definitely don't want a system that is so overcommited that performance is impacted, but if some overcommitment is reasonable for VM's that have light workload, then I consider that. I can increase system resources when that becomes necessary. Nataraj

Web server becoming unresponsive : high load
by robert mena 15 Mar '11

15 Mar '11

Hi, I have a web server which is randomly becoming unresponsive. I've checked for hardware problems with no luck : - no ethernet errors - no disk errors - no memory errors So far I've managed to point the trouble at the web server since if I restart httpd (apache) it comes back to normal. This is not a shared server so I control (or at least like to think of) what is hosted so I have two suspects: a) my own code is behaving strangely. For example, a php script that in a given situation/parameters increases the usage. b) some sort of attack. Either in conjunction to a or other vulnerability. I am looking for advices in how can I pin point since looking at every line of code would be infeasible. Centos 5.5 / apache / php 5.2.10

wich filesystem to store > 250E6 small files in same or hashed dire
by Alain Spineux 14 Mar '11

14 Mar '11

Hi I need to store about 250.000.000 files. Files are less than 4k. On a ext4 (fedora 14) the system crawl at 10.000.000 in the same directory. I tried to create hash directories, two level of 4096 dir = 16.000.000 but I had to stop the script to create these dir after hours and "rm -rf" would have taken days ! mkfs was my friend I tried two levels, first of 4096 dir, second of 64 dir. The creation of the hash dir took "only" few minutes, but copying 10000 files make my HD scream for 120s ! I take only 10s when working in the same directory. The filenames are all 27 chars and the first chars can be used to hash the files. My question is : Which filesystem and how to store these files ?

NFS still serving old directory after rename
by neubyr 14 Mar '11

14 Mar '11

Howdy, I have renamed a directory on NFS ver 3 server and then created a new directory again with the same name. # mv dir dir-hosed # mkdir dir The directory is auto-mounted on client side. I had unmounted directories on client side before making above changes. Now when I try to mount back 'dir', I still see old files and not new empty dir. Am I missing something here in the NFS config? Is it caching old directory contents? Any help? thanks, neuby.

Server locking up everyday around 3:30 AM - (INFO: task wget:13608 blocked for more than 120 seconds) need sleep, help.
by PJ 14 Mar '11

14 Mar '11

This may or may not be CentOS related, but am out of ideas at this point and wanted to bounce this off the list. I'm running a CentOS 5.5 server, running the latest kernel 2.6.18-194.32.1.el5. Almost everyday around 3:30 AM the server completely locks up and has to be power cycled before it will come back online. (this means someone hat to wake up and reboot the server, oh how I love being an internet janitor! :) Smells like a hardware issue to me too, but I went through all of the dell diagnostics, updated the firmware, everything checks out as being okay, RAID, disks, RAM, etc... Spent an hour on the phone with a Dell tech. No hardware issues, at least that we were able to find. There are no cron jobs that run at 3:30, no backups, the server has a load of 0, nothing is scheduled around that time... The only crontab entry at all is "*/5 * * * * wget -q www.websitedomain.com/cron.php >/dev/null 2>&1" They are running Magento for commerce purposes and this runs every 5 minutes. Why does the server only lockup around 3:30 AM? Because it's knows I am fast asleep? I was able to pull this from /var/log/messages, this happens just seconds before locking up completely... Mar 8 03:33:18 web1 kernel: INFO: task wget:13608 blocked for more than 120 seconds. Mar 8 03:33:19 web1 kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Not cheap, but worth the money. I assume the long power-on pause is due to the BIOS silently checking RAM, with the side effect of giving the disks ample time to spin up. I have a total of 15 drives. Three of them are fast 2-1/2" drives used for the host OS filesystems, running on the ICH-10 SATA controller. No problem at all with those. The other 12 drives are 2TB WD Caviar Black series. 6 are connected to the on-board 8-port LSI 1068E chip, and 6 divided equally between 2 Tempo 'Sonnet' 4-port PCIe cards (Marvell chips). All drives have the same 8 partitions each. All drives have the same 8-partition configuration. The LSI controller supports 8 RAID-6 arrays using 5 active drives plus a hot spare. The Tempo controllers support the same arrangement using the other 6 drives. The firmware on everything is up to date. Other than the annoying failure to bind 1 or 2 random partitions on the last drive in each group of 6, the performance of this configuration is quite good. I still have the 'scsi_mod.scan=sync' kernel parameter in place, so there may be some other cause of the failure to bind some of the partitions. FWIW, in more than 10 system boots, there has never been any consistent pattern to these failures. Chuck

Mumble gamers' VOIP server (murmur)
by Kenneth Porter 13 Mar '11

13 Mar '11

I was unable to build the whole Mumble system on CentOS but it's available for Fedora Development. I just wanted the server part on my headless server, and a static build is available from the Mumble project on Sourceforge. So I grabbed the Mumble SRPM from Fedora Development, the static build from Sourceforge, and stripped the spec file down to the minimum needed to just install the static-build server. You'll find the result here: <http://sewingwitch.com/ken/Stuff/murmur-1.2.3-11.kp.src.rpm> If you're paranoid (a good admin should be), just unpack to use the spec file and grab the sources from Fedora Development and Sourceforge and overwrite those included in the SRPM before building.

What iSCSI is used in Centos 5 and RHEL6?
by Emmanuel Noobadmin 12 Mar '11

12 Mar '11

I was looking up on iSCSI in preparation and became aware that there are different iSCSI software/drivers/whatever-is-the-correct-term available. e.g. IET http://iscsitarget.sourceforge.net/ SCST http://scst.sourceforge.net/ STGT http://stgt.berlios.de/ LIO http://linux-iscsi.org/ Based on what I can see, it seems to be STGT because the site provides a link to Redhat advisory which seems to imply that it's what's being used in RHEL. Does anybody know for sure?

There were delays after changes after delays for that project that was meant to run on the VM setup. Spent more time hacking temporary solutions to their problems with NAS and such. So I haven't actually got this done. But if you can wait, I could probably answer you in about 4 weeks... when the hardware and fibre connectivity for the client's server room comes in.

I don't have any choice as to when the drives are spun up (only on bootup), but I did try a controller card which pre-spun and checked the identification of the drives before handing off to the BIOS for bootup. That didn't help. On the particular Supermicro motherboard I'm using, there is a very long delay (10 or 15 sec) between power-on and initiation of visible BIOS activity, so all disk drives have ample time to spin up and stabilize. The drives' SMART data shows that the average spin-up time is well within the BIOS startup delay. Each drive activity indicator shows that they are always probed by the kernel's scsi scan process. I have since tried a couple of other tricks I found by Googling around ... setting the kernel parameters 'rootdelay=xx' and 'scsi_mod.scan=sync'. These had no effect on the problem. For some unfathomable reason, the last drives in each group of drives have one or more random partitions missing, with no 'bind' statement in dmesg. Other partitions on those drives are bound normally. This has been tested with at least two known-good replacement drives, with the same random results. On two occasions today, everything worked perfectly, but that was unusual. A friend of mine suggested an ugly hack - connect two 'dummy' unused old SATA drives to the last port of each controller (I'm using only 6 of 8 on each). I wonder if one of those $15 IDE-to-SATA converters would do the job (without a drive attached)? Foolish thought :-/ Chuck

screen saver unlock dialog window is not visible in clone mode
by DarkKnight BrightWarrior 12 Mar '11

12 Mar '11

Hi, Environment: I am using CentOS 5.3 operating system. I upgraded xorg of centos to 7.3. I am using intel 945 GM board. My xorg server version is 1.4.2 and inetl driver version 2.4.3. gnome-screensaver version is 2.16.1-8.el5. Problem: I connected another system of same hardware using VGA output. Now I can see clone of my system on secondary display. I enabled screensaver with 1 minute period and also enabled locking feature using gnome-screensaver-preferences. After 1 minute screensaver appeared on both primary and secondary displays. But when I move mouse or press any key, Screen saver unlock dialog is not appearing. But when I type password, I am able to comeout of screensaver. So Screensver unlock dialog is there but it is not visible. When I remove secondary display, I mean when I am in single display mode screen saver unlock dialog is visible and working fine. So what could be the problem that causing screensaver unlock dialog window to appear/visible in clone/extended monitor mode. Please help. Thanks

debugging auto mount configuration
by Boris Epstein 11 Mar '11

11 Mar '11

Hello there, I successfully use automount to mount a large XFS pargtition on one CentOS 5.5 machine. I then tried to do the same thing on a different machine - and it simply would not work! The configuration is done in the same fashion, I checked and double-checked the syntax - but it is still a no go. When I use the mount command the partition mounts perfectly. I have tried running automount --debug and automount --verbose and thus far have not seen any messages that would shed any light on what's going on. So I am a bit lost at the moment. Any advice on how to proceed would be much appreciated. Boris.

Hi, We are running on 5.5 on a HP ProLiant DL360 G6.

We are seeing very bad and inconsistent performance on the UDP testing. The maximum we could get, was 440 Mbits/sec, and it varies from 250 to 440 Mbits/sec. We are connected on a 1000Mb/s link, we also tested the same using a cross-over connections between the two machines, but the same performance. We also see a lot of dropped UDP packets. Udp: 551522838 packets received 1902 packets to unknown port received. 109709802 packet receive errors 7239 packets sent We had checked all the kernel configurations and set them as recommended.

Installation failure
by Mark 11 Mar '11

11 Mar '11

I'm trying to reinstall CentOS on a machine I've reconditioned for it, but for reasons I can't fathom, when the installation disk comes up and prompts for the install type, and I type either <enter> (graphics isntall) or "linux text"<enter>, after it loads the initrd image, the machine shuts off. It's an older machine I built myself (and ran CentOS on for a number of years), AMD Athlon 64 x2, 2GB of memory, 2 SATA hard drives, ECS GE6100PM-M2 motherboard. I should probably even know the answer to this one, but I'm stumped. Any suggestions? Thanks.

Race condition with mdadm at boot [still mystifying]
by Chuck Munro 11 Mar '11

11 Mar '11

This is a bit long-winded, but I wanted to share some info .... Regarding my earlier message about a possible race condition with mdadm, I have been doing all sorts of poking around with the boot process. Thanks to a tip from Steven Yellin at Stanford, I found where to add a delay in the rc.sysinit script, which invokes mdadm to assemble the arrays. Unfortunately it didn't help, so it likely wasn't a race condition after all. However, on close examination of dmesg, I found something very interesting. There were missing 'bind<sd??>' statements for one or the other hot spare drive (or sometimes both). These drives are connected to the last PHYs in each SATA controller ... in other words they are the last devices probed by the driver for a particular controller. It would appear that the drivers are bailing out before managing to enumerate all of the partitions on the last drive in a group, and missing partitions occur quite randomly. So it may or may not be a timing issue between the WD Caviar Black drives and both the LSI and Marvell SAS/SATA controller chips. So, I replaced the two drives (SATA-300) with two faster drives (SATA-600) on the off chance they might respond fast enough before the drivers move on to other duties. That didn't help either. Each group of arrays uses completely drivers (mptsas and sata_mv) but both exhibit the same problem, so I'm mystified as to where the real issue lies. Anyone care to offer suggestions? Chuck

Any reliable way to determine LVM snapshot creation time?
by Dr. Ed Morbius 10 Mar '11

10 Mar '11

We utilize LVM snapshots for some periodic maintenance. They're manually created and, usually, manually destroyed. But not always. So there's now a nightly script monitoring for open snapshots. Which raises the question of when a given snapshot was created. Absent good practices of, say, using sudo to create snapshots (leaving a /var/log/secure message), is there any reasonably reliable way to determine when an LVM was created? There's a timestamp on the /dev/mapper/<snapshot> file. I'm presuming that's somewhat useful for this purpose? Ah: just found /var/log/messages also indicates: lvm[2314]: Monitoring snapshot <name> lvm[2314]: No longer monitoring snapshot <name> ... which I think answers my own question.

Dell PERC H800 commandline RAID monitoring tools
by Dr. Ed Morbius 10 Mar '11

10 Mar '11

We're looking for tools to be used in monitoring the PERC H800 arrays on a set of database servers running CentOS 5.5. We've installed most of the OMSA (Dell monitoring) suite. Our current alerting is happening through SNMP, though it's a bit hit or miss (we apparently missed a couple of earlier predictive failure alerts on one drive). OMSA conflicts with mega-cli, though we may find that the latter is the more useful package. Both are pretty byzantine, the Dell stuff simply doesn't have docs (in particular: docs on how to interpret the omconfig log output). Ideally we'd like something which could be run as a Nagios plugin or cron job providing information on RAID status and/or possible disk errors. Probably both, actually.
