[Linux-cluster] Updating issues

2008-05-29 Thread denis
While doing a yum update on one RHCS node I got this: Transaction Check Error: file /etc/depmod.d/gfs2.conf from install of kmod-gfs2-1.92-1.1.el5 conflicts with file from package kmod-gfs2-1.52-1.16.el5 This node does not use GFS2 (and I already unmounted any GFS1 volumes anyway), so I

[Linux-cluster] LVM hanging during mkinitrd checks

2008-05-29 Thread denis
During the update to RHEL5.2 I had another problem. The mkinitrd process would hang indefinitely while scanning my block devices with lvm.static lvs --ignorelockingfailure --noheadings -o vg_name blockdev stracing the lvs process showed no signs of life. It hung on random function calls (I

[Linux-cluster] cman_tool returns Flags: Dirty

Hi list, Sorry for the noise, but I thought posting my results with the update to RHEL5.2 would be of interest to a few of you. The node that has been updated to RHEL5.2 seems to operate very nicely in the cluster so far. After a boot it did rejoin the cluster, and got back its affinity

[Linux-cluster] GFS in a small cluster

2008-05-29 Thread Kees Hoekzema
Hello List, Recently we have been looking at replacing our NFS server with a SAN in our (relatively small) webserver cluster. We decided to go with the Dell MD3000i, an iSCSI SAN. Right now I have it for testing purposes and I'm trying to set up a simple cluster to get more experience with it. At

[Linux-cluster] apache resource problem in RHCS 5.1

2008-05-29 Thread Lorenz Pfiffner
Hello everybody I have the following test setup: - RHEL 5.1 Cluster Suite with rgmanager-2.0.31-1 and cman-2.0.73-1 - Two VMware machines on an ESX 3.5 U1, so no fence device (it's only a test) - 4 IP resources defined - GFS over DRBD, doesn't matter, because it doesn't even work on a local
