Hi All,
Need the suggession for the folling issues :
Operating System : rhel 5.5 , 86_64
In our environment, 16 nodes are in cluster and shared storage is being used.
Multipath is used, and there was no aliases. The admins created the disk,
with the /dev/dm....
Now they changed the multipath config file and incorporated the aliases.
The alias names are as follows:
HOST-1TB-CLVM-VG04-DISK1
HOST-1TB-CLVM-VG02-DISK1
and so on.
They use the filter in lvm.conf as filter = [ "r/scsi.*/","r/pci.*/","r/sd.*/","a/.*/" ]
They did not enable the "preferred_names" option in lvm.conf
Now the problem is, lvm related any commands are getting hung.
While debugging the issue I activated the "preferred_names" option in lvm.conf
and found the errors as follows:
[root@server ~]# lvs
File descriptor 4 (/dev/pts/0) leaked on lvs invocation. Parent PID 20817: bash
WARNING: Ignoring duplicate config node: preferred_names (seeking preferred_names)
I mentioned literally all the vgnames under "preferred_names" in lvm.conf but still the
errors are same.
If anybody gives some suggesstion , how to rectify the issue that will be really helpful.
Thanks in advance
