CFSumount hangs on RHEL6.1 with veritas 5.1SP1PR2

Created: 14 Dec 2011 | 1 comment

Hello,

I'm using two RHEL6.1 servers with veritas 5.1SP1PR2 cluster file system. Cluster starts ok and I can switch services to other node etc but when I execute commands hastop -local or hastop -all then the cluster hangs.

It even makes one of the nodes to hang totally and no commands cannot be executed as root.

What I can see is that it hangs when it does the cfsumount for shared mount points. Some of them (changes time to time so not the same mount points) are hanging and appead again to the mount list but not as real mounts but as copies of root /. example below

-bash-4.1# df -k
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                       8256952   5710140   2127384  73% /
tmpfs                 18503412       424  18502988   1% /dev/shm
/dev/sda1               253871     37102    203662  16% /boot
/dev/mapper/VolGroup00-LogVol04
                      12385456    863508  10892804   8% /opt
/dev/mapper/VolGroup00-LogVol02
                       8256952    428260   7409264   6% /tmp
/dev/mapper/VolGroup00-LogVol03
                      12385456   5429820   6326492  47% /var
tmpfs                        4         0         4   0% /dev/vx
/dev/vx/dsk/mountdg/mymount
                       8256952   5710140   2127384  73% /mymount

From here you can see that the data values are the same between my cfsmount (mymount)  and root /. I can survive from this using command umount  /mymount

It throws an error
umount: /mymount: not mounted

but still ater this cluster continues to go down. This is just a workaround and I do not want to leave it like this.

Any ideas how to fix this? Is there a patch for this or should I change something on RHEL or in veritas?

br, JP
