looking for kernel sources
by Rudi Ahlers 04 Mar '08

04 Mar '08

Hi all I'm looking for the linux source files for CentOS 5.1 2.6.18-53.el5. To install VirtualBox, I apparently need the kernel sources, and even after installing kernel-devel & kernel-headers via yum I still get an error saying I need the kernel-sources [root@gimbli ~]# ll /usr/src/kernels/ total 4 drwxr-xr-x 18 root root 4096 Mar 4 10:57 2.6.18-53.1.13.el5-x86_64 lrwxrwxrwx 1 root root 43 Mar 4 10:57 linux -> /usr/src/kernels/2.6.18-53.1.13.el5-x86_64/ [root@gimbli ~]# ll /usr/src/kernels/linux/ total 716 drwxr-xr-x 26 root root 4096 Mar 4 10:57 arch drwxr-xr-x 2 root root 4096 Mar 4 10:57 block drwxr-xr-x 4 root root 4096 Mar 4 10:57 crypto drwxr-xr-x 63 root root 4096 Mar 4 10:57 drivers drwxr-xr-x 63 root root 4096 Mar 4 10:57 fs drwxr-xr-x 20 root root 4096 Mar 4 10:57 include drwxr-xr-x 2 root root 4096 Mar 4 10:57 init drwxr-xr-x 2 root root 4096 Mar 4 10:57 ipc -rw-r--r-- 1 root root 56915 Feb 12 20:23 kabi_whitelist drwxr-xr-x 5 root root 4096 Mar 4 10:57 kernel drwxr-xr-x 5 root root 4096 Mar 4 10:57 lib -rw-r--r-- 1 root root 48120 Feb 12 20:24 Makefile drwxr-xr-x 2 root root 4096 Mar 4 10:57 mm -rw-r--r-- 1 root root 167056 Feb 12 20:24 Module.kabi -rw-r--r-- 1 root root 328848 Feb 12 20:24 Module.symvers drwxr-xr-x 40 root root 4096 Mar 4 10:57 net drwxr-xr-x 10 root root 4096 Mar 4 10:57 scripts drwxr-xr-x 4 root root 4096 Mar 4 10:57 security drwxr-xr-x 18 root root 4096 Mar 4 10:57 sound -rw-r--r-- 1 root root 45633 Feb 12 20:24 symsets-2.6.18-53.1.13.el5.tar.gz drwxr-xr-x 2 root root 4096 Mar 4 10:57 usr From this list of files it seems like yum might have installed the wrong version?

LVM and kickstarts ?
by Michael Gale 04 Mar '08

04 Mar '08

Hey, Can anyone tell me why option 1 works and option 2 fails ? I know I need swap and such, however in trouble shooting this issue I trimmed down my config. It fails on trying to format my logical volume, because the mount point does not exist (/dev/volgroup/logvol) It seems that with option 2, the partitions are created and LVM is setup correctly. However the volgroup / logvolume was not made active, so my /dev/volgroup/logvol did not exist. Running `lvm lvchange -a -y pathname` from with in the shell after anaconda failed made the volgroup / logvol active. Which would allow the format command to complete. Option 1: zerombr yes clearpart --all --initlabel part /boot --fstype ext3 --size=100 part pv.os --size=10000 --grow --maxsize=10000 --asprimary volgroup os_volgroup01 pv.os logvol swap --fstype swap --name=os_swap_logvol --vgname=os_volgroup01 --recommended logvol / --fstype ext3 --name=os_root --vgname=os_volgroup01 --size=1024 --grow Option 2: zerombr yes clearpart --all --initlabel part /boot --fstype ext3 --size=100 part pv.os --size=10000 --grow --maxsize=10000 --asprimary volgroup os_volgroup01 pv.os logvol / --fstype ext3 --name=os_root --vgname=os_volgroup01 --size=1024 --grow -- Michael Gale Red Hat Certified Engineer Network Administrator Pason Systems Corp.

crypto, readline and zlib libraries - Postgres install
by Karl Denninger 04 Mar '08

04 Mar '08

I have the 5.x Centos DVD and loaded it. Please be gentle with me, as I'm nominally a FreeBSD kind of guy... :) Anyway, I'm trying to install Postgres and the three libraries in the subject line are missing off the base installation. I figured out how to load gcc using yum, but those libraries aren't there, and I need the former in particular in order to enable SSL for Postgres client connections. A perusal of "yum list" with an appropriate grep or two doesn't elicit anything useful. Anyone know where I find these? I loaded just the standard distro, no graphical user environment (neither Gnome or KDB) Thanks in advance. -- Karl Denninger (karl(a)denninger.net) http://www.denninger.net

install LAMP
by Hiep Nguyen 04 Mar '08

04 Mar '08

hi all, i'm not an expert on linux/centos, but i play with it and have a general idea. it's time for me to setup a centos box for development. i rarely install anything from source, except a few times in college when i have to modify kernel for OS project. but i guess i can learn now. i just installed centos 5 with minimal installation. next step is to install LAMP w/ SSL. i found http://lamphowto.com/lampssl.html, but i have questions before i proceed. is it better to install from source or rpm? how easy it is to upgrade/update if install from source? it seems so much easy to upgrade/update from rpm, well b/c i'm always do this way. is there any other instruction (beside the one mentioned above) to install LAMP w/ SSL? appreciate your help/suggestion t. hiep

Device-mapper-multipath not working correctly with GNBD devices
by Svetoslav Rogalski 04 Mar '08

04 Mar '08

Hi all, I am trying to configure a failover multipath between 2 GNBD devices. I have a 4 nodes Redhat Cluster Suite (RCS) cluster. 3 of them are used for running services, 1 of them for central storage. In the future I am going to introduce another machine for central storage. The 2 storage machine are going to share/export the same disk. The idea is not to have a single point of failure on the machine exporting the storage. For concept testing I am using one machine on which I have configured 2 GNBD exports, which are exporting exactly the same disk. These are configured with: # /sbin/gnbd_export -d /dev/sdb1 -e gnbd0 -u gnbd # /sbin/gnbd_export -d /dev/sdb1 -e gnbd1 -u gnbd They are exporting with the same id, so the multipath driver will automatically configure them as alternative paths to the same storage. Now on one of the cluster nodes used for running services I am importing these GNBD devices with: # /sbin/gnbd_import -i gnbd1 where gnbd1 is the hostname of the machine exporting the GNBD devices. And I have these imported ok: # gnbd_import -l Device name : gnbd1 ---------------------- Minor # : 0 sysfs name : /block/gnbd0 Server : gnbd11 Port : 14567 State : Open Connected Clear Readonly : No Sectors : 41941688 Device name : gnbd0 ---------------------- Minor # : 1 sysfs name : /block/gnbd1 Server : gnbd1 Port : 14567 State : Open Connected Clear Readonly : No Sectors : 41941688 # After, I have configured the device-mapper multipath by commenting the "blacklist" section in /etc/multipath.conf and adding this "defaults" section: defaults { user_friendly_names yes polling_interval 5 #path_grouping_policy failover path_grouping_policy multibus rr_min_io 1 failback immediate #failback manual no_path_retry fail #no_path_retry queue } Now I have the mpath device configured correctly (IMHO): # multipath -ll mpath0 (gnbd) dm-2 GNBD,GNBD [size=20G][features=0][hwhandler=0] \_ round-robin 0 [prio=2][enabled] \_ #:#:#:# gnbd0 252:0 [active][ready] \_ #:#:#:# gnbd1 252:1 [active][ready] # # dmsetup ls mpath0 (253, 2) VolGroup00-LogVol01 (253, 1) VolGroup00-LogVol00 (253, 0) # Now I mkfs.ext3 over the mpath0 device to create a filesystem, then mount. After I start to copy a file (with scp - to have a progress bar) and during the copy process I shutdown one of the exported GNBD device on the disk exporting machine with: # gnbd_export -r gnbd1 -O After a while in the maillog: gnbd_recvd[3357]: client lost connection with gnbd11 : Broken pipe gnbd_recvd[3357]: reconnecting kernel: gnbd1: Receive control failed (result -32) kernel: gnbd1: shutting down socket kernel: exiting GNBD_DO_IT ioctl kernel: gnbd1: Attempted send on closed socket gnbd_recvd[3357]: ERROR [gnbd_recvd.c:292] login refused by the server : No such device gnbd_recvd[3357]: reconnecting kernel: device-mapper: multipath: Failing path 252:1. multipathd: gnbd1: directio checker reports path is down multipathd: checker failed path 252:1 in map mpath0 multipathd: mpath0: remaining active paths: 1 gnbd_recvd[3357]: ERROR [gnbd_recvd.c:292] login refused by the server : No such device gnbd_recvd[3357]: reconnecting Now the copy process is freezed. It stays that way until the GNBD device is exported again. I try some commands on the multipath machine: # multipath -ll gnbd1: checker msg is "directio checker reports path is down" mpath0 (gnbd) dm-2 GNBD,GNBD [size=20G][features=0][hwhandler=0] \_ round-robin 0 [prio=1][active] \_ #:#:#:# gnbd0 252:0 [active][ready] \_ #:#:#:# gnbd1 252:1 [failed][faulty] <freezed, the prompt is not returning back> This prompt get back after the GNBD device is exported again. My expectations were that in such a scenario the multipath driver is going to switch the requests to the other path and everything should continue to work. Am I wrong? I have upgraded to the last version of all the RPMs. I am using CentOS 5.1. I have tried different multipath settings (which are commented out in the multipath.conf "defaults" section I pasted previously), but nothing happens. This may be useful. When starting the machine in the log: multipathd: gnbd0: add path (uevent) kernel: device-mapper: multipath round-robin: version 1.0.0 loaded multipathd: mpath0: load table [0 41941688 multipath 0 0 1 1 round-robin 0 1 1 252:0 1000] multipathd: mpath0: event checker started multipathd: dm-2: add map (uevent) multipathd: dm-2: devmap already registered gnbd_recvd[3357]: gnbd_recvd started kernel: resending requests multipathd: gnbd1: add path (uevent) multipathd: mpath0: load table [0 41941688 multipath 0 0 1 1 round-robin 0 2 1 252:0 1000 252:1 1000] multipathd: dm-2: add map (uevent) multipathd: dm-2: devmap already registered Maybe this is a bug of GNBD not the multipath? Any help for getting this working will be very appreciated. Thanks.

phpmyadmin hang..
by Frank M. Ramaekers 04 Mar '08

04 Mar '08

It seems that I can never get through a phpmyadmin session w/o it hanging on "Waiting for http://....". The only way I have found to correct this is to cycle Apache. I can always get past the signon portion, but it hangs at various portions of selecting DBs or Tables. CPU is not overly active, all httpd daemons running, no myphpadmin remnants running. Can't find any problems in the httpd log files. I've searched the web, but no applicable hits. Anyone been there? Frank M.
