what does:

mount -p

say?

make sure neither you nor anyone else or any other processes are using /test as their current directory. If it still fails, create a temporary directory like /test2 and try mounting it to this directory instead to isolate the problem.

There is no entry for lvol11 in mount -p.

whether we have to change any kernel parametrs to increase the allowable mount points.

Using fuser or lsof to find out whether any user is in /test.

[Michal Kapalka (mikap)]

hi,

fuser should be the best way,

maybe somebody exported the /test folder via NFS.

Hi Tinqli,

Thanx for ur reply.

fuser throws below error.

fuser -cu test
test: fuser: could not find file system mounted at test.

[Michal Kapalka (mikap)]

Hi,

fuser -cu /test

[himacs]

Hi mikap,

I have created new dir check as mountpoint.

fuser -cu /check
/check: fuser: could not find file system mounted at /check.
>mount /dev/vg00/lvol12 /check
vxfs mount: /dev/vg00/lvol12 is already mounted, /check is busy,
allowable number of mount points exceeded
