problem with mounting a file system

[Vipin Singhal]

today i think -my file system got unmount.
when i trying with #bdf, it shows this error:

bdf: /vipin I/O error

till yesterday , the status was:

#bdf
/dev/vg5/vipin 3584000 2065376 1423717 59% /vipin

Please suggest what to do?
thanks

Hi,

It has not got unmounted instead it has got some corruption.

What is the output of

#lvdisplay -v /dev/vg05/vipin

Was something new done on system like adding/removing LUNs, Extending/Reducing File System?
If yes then it is the result of the same probably otherwise generally it should not happen by itself.

What happen if you unmount and do a fsck on it.

HTH,

hi Vipin

but vg5 is active if you run vgdisplay vg05 what can you see?

Can you run #lvdisplay on your volume to see the results ? Is it a device connected to a SAN and got disconnected elsewhere ?

Hi,

Try
#umount /vipin

And

#mount /devvg5/vipin /vipin

If it reports error then try

#fsck -y /dev/vg5/vipin

Now Again

#mount /devvg5/vipin /vipin

HTH,
Devender

# mount -F vxfs /dev/vg5/vipin /vipin
