WD RE4-GP Dropped From Raid
by Steve Brooks 01 Apr '11

01 Apr '11

Hi All, I have a WD RE4-GP which dropped an Adaptec 51645 RAID controller. I ran a smartctl short test on the drive and it failed with a read error. So I ran the Western Digital's own diagnostic software (DLGDIAG), both the short and extended test on the drive and it passed with no errors. So I ran the smartctl short test again and again it failed. I then ran smartctl long test and that also failed at the same logical block address as the short test. Can anyone shed any light on this? Can I RMA the drive even if it passes Western Digital's own tests? Thanks in advance for any advice. Cheers, Steve

logical volume - device present without table
by neubyr 01 Apr '11

01 Apr '11

I am trying to mount a logical volume for creating new initrd image. The lvs command is showing a logical volume with 'd' attribute - device present without tables. It's getting listed under /dev/mapper but not under /dev/VolGroup00. Any help on what might be wrong here? -- thanks, neuby.r

script question
by Jerry Geis 31 Mar '11

31 Mar '11

I can do "simply" search and replace with sed. However, I want to setup httpd.conf from a script that changes the default "/" which is presently: <Directory /> Options FollowSymLinks AllowOverride None </Directory> and change it to the following: <Directory /> Order Deny,Allow Deny from all AllowOverride None </Directory> How do you do that with scripts? Basically substitute everything between the two Directory tags. Thanks, Jerry

Re: [CentOS] CentOS Digest, Vol 74, Issue 31

thanks for the reply, Phil It would, were udev not inserting USB and/or eSATA drives at /dev/sdb1 and/or /dev/sdc1 and exposing the array to the udev rule intended to handle only removable devices (at sdc or sdd). The array then mounts unpredictably in /media/xxx-sdc1 or sdd1 - not what is wanted - depend on how many removable devices are plugged at the time of rebooting. Of course, a single removable device will camp at sdb, which is out of reach of udev so the whole hotplug thing is broken until someone removes all of the devices at site, allowing a clean boot. mapper correctly places the / filesystem higher in position in rc.sysinit, followed by start_udev (where the damage gets done) and finally fstab evaluation way down the line. I suppose i could just hardwire the array mount into rc.sysint to engage after modules get loaded and hopefully before start_udev, unless there is a better way to enforce it. I'm not sure at this stage (need to analyse that ~1000-line script) if there is a suitable insertion point. It would be really good if it could be done outside of rc.sysint in some predictable place. We're "stuck" (but not unhappily) with this kernel/rev for the foreseeable future - i have over 100 of these systems and they are housed behind VPN'd networks, which mitigates somewhat their inevitable vulnerabilities. regards, - csawyer 30. Re: Controlling the order of /dev/sdX devices? (Phil Schaffner) CentOS 5.4(final) 2.6.18-164el5PAE. I am trying to prevent removable USB and eSATA devices from occupying /dev/sdX devices ahead of a 3ware RAID controller. For example: at boot, if a USB drive and eSATA HDD (connected to an LSI 1068E onboard controller, reflashed in "IT" mode to handle hotplug devices) were both present, they would occupy devices /dev/sdb and /dev/sdc, ahead of the RAID controller which ends up as /dev/sdd. As these are removable devices, they should normally get handled by custom udev script looking for adds matching KERNEL=="sd[c-z][0-9]" ,SUBSYSTEM=="block", so the volume handled by RAID controller gets grabbed by udev but fails to mount and subsequent udev plug events fails due the slots left empty below /dev/sdd. If no hotplug devices are present while booting, fstab handles mounting of the system and RAID volume: SATA system HDD /dev/VolGroup00/LogVol00 / RAID array LABEL=STORE /store ## mounts == /dev/sdb1 I realise this description is kind of a tangle, but i am essentially looking for a way to hard-map the 3ware RAID controller to /dev/sdb (UUID won't work as there are multiples of this system) before PCI (?) enumeration picks up the USB and LSI-managed devices so that udev can take care of the device at /dev/sdc and above. I've tried blacklisting the mpt and usb-storage modules and short-circuiting SUBSYSTEM=="block" devices in 05-udev-early.rules, all with zero or negative effect. rc.sysinit doesn't appear to be the right place and that's about as deep down as i know how to go. cheers, cs ------------------------------ Message: 30 Date: Thu, 31 Mar 2011 10:24:42 -0400 From: Phil Schaffner <Philip.R.Schaffner(a)NASA.gov> Subject: Re: [CentOS] Controlling the order of /dev/sdX devices?

Why does a line in /etc/fstab like LABEL=STORE /store ext3 defaults 1 2 not work?

Virtualization platform choice
by Jussi Hirvi 31 Mar '11

31 Mar '11

Some may be bored with the subject - sorry... Still not decided about virtualization platform for my "webhotel v2" (ns, mail, web servers, etc.). KVM would be a natural way to go, I suppose, only it is too bad CentOS 6 will not be out in time for me - I guess KVM would be more mature in CentOS 6. Any experience with the free "VMware vSphere Hypervisor"?. (It was formerly known as "VMware ESXi Single Server" or "free ESXi".) http://www.vmware.com/products/vsphere-hypervisor/overview.html I would need a tutorial about that... For example, does that run without a host OS? Can it be managed only via Win clients? Issues with CentOS 4/5 guests (all my systems are currently CentOS 4/5). - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi(a)greenspot.fi * http://www.greenspot.fi

OT: IBM and Dell rack
by Fajar Priyanto 31 Mar '11

31 Mar '11

Hi all, sorry for the OT. Is IBM and Dell 42U rack compatible in dimension, rails, etc? Can we put IBM servers into Dell rack? Google says it depends. Much appreciated if you can share your experience. http://www.server-racks.com/why-all-racks-are-not-created-equal.html Thank you.

nlockdmgr listen on privileged port
by Tim Dunphy 31 Mar '11

31 Mar '11

hey list! I am attempting to shore up some centos machines (ranging from centos 5 to centos 5.4) for pci compliance by changing the port that nlockdmgr listens on to function under a privileged port. So what I did was try to hardcode the port by editing /etc/sysconfig/nfs # TCP port rpc.lockd should listen on. LOCKD_TCPPORT=1011 # UDP port rpc.lockd should listen on. LOCKD_UDPPORT=1011 # And /etc/modprobe.conf alias eth1 e1000e alias scsi_hostadapter 3w-9xxx alias scsi_hostadapter1 usb-storage alias eth0 e1000e options lockd nlm_udpport=1011 options lockd nlm_tcpport=1011 and then restarting the pormap service. I've even tried restarting the network service, but unfortunately nothing seems affected: [root@stallion:/etc/init.d] $ rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100021 1 udp 55394 nlockmgr 100021 3 udp 55394 nlockmgr 100021 4 udp 55394 nlockmgr 100021 1 tcp 33704 nlockmgr 100021 3 tcp 33704 nlockmgr 100021 4 tcp 33704 nlockmgr 100024 1 udp 786 status 100024 1 tcp 789 status Does anyone have any tips on how to get this to work the way I'm asking it to? regards ~ GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Hello,guys: I try to compile heartbeat 3.0.4 from official sources on CentOS 5.5 x86_64 .

No configure: error: Core development headers not found What is the meaning of that message? In other words, is it the something that had not been installed ? Thanks in advanced......
