what's strange here is that this error is associated with mounting a CFS filesystem in a nested mount point - but looking at the output above you don't seem to be doing that... it would be interesting to see if there are any differnces betrween your mount options... what do you get from:

cfsmntadm display -v /u05

compare with:

cfsmntadm display -v /abb

Hi,

Thanks for the reply,

But I cant find the command cfsmntadm in my server,

This is VxVM configure unders MC service guard cluster,

SO you don't have CFS installed on this system? That's even stranger then... care to share the relevant section of the Serviceguard package control file? (i.e. the bit that defines the filesystem mounts)

well the only difference I see is the lack of largefiles flag for the /abb filesystem, but that shouldn't prevent it mounting.

What do you see from the following?

fstyp -v /dev/vx/dsk/appl/abb

mkfs -F vxfs -m /dev/vx/dsk/appl/abb

also confirm that when the package is in a halted state the /abb filesystem isn't mounted... (make sure someone hasn't put it in /etc/fstab)

Hi Duncan,

the package is running on adoptive node at the moment, I did check that on other node. both the control scripts are same,

Even though the file system is not mounted with largefiles option enabled i am sure that should not be a problem,

This FS is mounted and working fine on adoptive node but getting these errors while failback.

Thanks & Regards,
Govinda.

so stupid I know, but the /abb directory does exist on the adoptive node doesn't it?

aslo check that the mount point isn't busy for other reasons:

fuser /abb

should return

# fuser /abb
/abb:

indicating no processes accessing the directory.

Hi,

Try running the processes manually.

Stop your appl, run fuser on all the FS's, unmount the FS's, then deport the dg-group.

Then try to import the dg-group on the failover server and mount the FS's manually?

This has help me when I have had problems.
