Function check_and_mount - Cannot mount filesystem

WSS — Wed, 08 Feb 2006 07:17:21 GMT

Hi All,

For some reason I cannot start a package within service guard, and it's telling me it's because it's trying to mount a filesystem that's already mounted - But the filesystem is certainly not mounted, so why is it saying this???

*Extract from pkg log file*

Shalom,

/dev/vgclwss/lvwsst01 is already mounted, /wssprod is busy,
allowable number of mount points exceeded

I would surmise that the folder /wsprod is busy or the activation of volume group /dev/vgclwss failed.

Hi,

Probably someone is positioned in the directory /wssprod.

Try to find out who (check the currently login session)

If you cannot find it, then i am afraid you have to reboot the server to clear the mountpoint

Hi,

While the cluster gone it would not have goes properly, you need to activate the VG

use vgchange -a y -s and try to mount manaully once.

Then once again start the pkg

Hi,

Do you start this package for the first time on the server. If so make sure you have the mount point in place. Futher more do an fuser on the filesytem where it had run.
Second if nothing works.
Tyr to do the following.
vgchange -c n /dev/vgclwss/lvwsst01
vgchange -a y /dev/vgclwss/lvwsst01
mount /dev/vgclwss/lvwsst01 mountpoint.
If you can mount the filesystem then unmount.
vgchange -a n /dev/vgclwss/lvwsst01
vgchange -c y /dev/vgclwss/lvwsst01
vgchange -e y /dev/vgclwss/lvwsst01

After this try to start the package again.

grtz. Mark

The problem is now sorted....

Thanks to Luk who nailed it. Someone was postioned in /wssprod, making it busy, therefore not being able to mount it.

Thanks again for all your answers, and special thanks to Luk.
