problem with mounting a file system

[Arunvijai_4]

Yes, recreating a new FS will destroy all datas on the disk. So, beware of it.

Do you have a recent backup of the filesystem?

Vipin,

Looks as like your mnttab has been corrupted.

# mv /etc/mnttab /etc/mnttab.old
# mount -a

# bdf
# cat /etc/mnttab

btw, yes you would loose your data if you use a newfs command.

Dear Vipin,

Yes! when you recreate the file system , the data will be LOST :-(

With Regards,

Siva.

When you see the error message: I/O error

there is nothing you can do to fix the problem--the disk is damaged and cannot be repaired. This isn't just the vipin volume, it is one of disks in /dev/vg5. Ideally, thes edisks are mirrored (optional software) but since you are seeing the disk I/O error message, this is probably not true. Not the rest of the lvogical volumes in /dev/vg5 may be OK, so IMMEDIATELY shuitdown your application(s) and take a backup of these volumes. Since you can't mount /vipin, there is no way to backup that data. Then go through the normal procedures to replace the failed disk and rebuild /dev/vg5.
