Problem IC62322
|
Status: Closed |
MOUNTV95_STOP.KSH CANNOT OFFLINE MOUNT RESOURCE ON AIX |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
On Aix, with multiple filesystems on a machine, the mount may
not be able to offline and the resource becomes 'Stuck Online'.
If the mount monitor interval is longer, the chances of the
'Stuck Online' state occurring is lower.
This is because the mountV95_stop.ksh script unmounts the
filesystem, and tries to varyoff the vg if all other mounts in
that vg are unmounted. When mountV95_monitor.ksh runs during
the stop and, if it sees the fs unmouned but the vg is online,
it
will remount the filesystem. This creates a race condition
where sometimes mounts can't be offline and the resource
becomesStuckOnline. |
