HACMP: shared filesystems think they are in rootvg
Env: AIX 4.1.5, Model: SP, HA 4.2.2 with no enhancements
Problem: HACMP veryify ... fails
Customer indicates that when she tries to verify/sync she gets
some errors including: 'volume group rootvg is set to autovaryon
on node X'. Why are we getting an error about rootvg this way.
Verifying SERVICE_LABEL: ddsnode13_srvc
Verifying Filesystem: /accting
ERROR: Volume Group rootvg on Node rocky is configured to
ERROR: Logical Volumes, Volume Groups, Log Logical Volumes and/or
PVIDs associated with filesystem '/accting' are not equivalent on
Action Taken: Looking at her setup, it could be that the filesystem
listed /home is part of rootvg.
Checked the filesystems that are part of the resource group.
/accting and /acctsys are part of prismvg and /home is part of
SPhome. The error being received about rootvg being set to
autovaryon is our main problem. The other error is probably
caused by the system she is trying to sync to does not know
about the prismvg as it is supposed to, needs to export and then
Talked with customer and went through process of
elimination to find out which filesystem is causing the
problem: It looks like /accouting and /spdata on the standby
system. When this is put in the resource group and then synced
it gives the error about rootvg is set to autovaryon.
At this point the customer's time ran out for normal hours
so we will pursue this on Monday.
Action Taken: Customer ran some more tests and it looks like /accounting
and /sphome both cause the HA sync to fail. Looked in
/etc/filesystems and /sphome's LV is /dev/sphome which is
in a shared VG. Had customer run:
getlvcb -AT hd1 does show /sphome as the mount point.
It looks like cl_fs2disk looks in every LV's control block
for the mount point and it happened to find hd1 before
sphome of course did not have an entry in /etc/filesystem and
so we could just remove the LV. After that cl_fs2disk returned
what we expected for /sphome. A similiar problem was found with
/accounting and we fixed that.
We were then able to synchronize successfully.
Action Plan: close
