Hello everybody,
I have a computer acting as an NFS Server running a Debian based distro
and several hosts running CentOS 6.2 acting as NFS clients (for a
virtualization environment). Every time more often "Stale NFS file
handle" errors appear when trying to copy a file from one directory to
another (both in the nfs shared directory).
In the server side there are no related information in the logs, but
this is the output of one of the nfs clients:
Wed Aug 29 11:52:57 2012 [TM][E]: clone: Command "cd
/var/lib/one/datastores/0/32; cp -r
../../1/5c0455eb494fd43b5c7c576e0c642fbe
/var/lib/one/datastores/0/32/disk.0" failed: cp: reading
`../../1/5c0455eb494fd43b5c7c576e0c642fbe': Stale NFS file handle
I've checked that path and filenames are correct. The file itself is a
300MG sized and the error appears aprox. 30 minutes after the start of
the copy, so I guess that it doesn't finish the file copy.
I usually tried unmounting and remounting the shared directory. In fact,
initially it was enough and it was possible to fully copy the file
(after aprox. 30 minutes), moreover because the error took place from
time to time. But now, the problem persists after doing it (even after
rebooting the clients).
Additionally, I've tried doing the same operation (to copy the same file
from a directory to another) locally in the NFS Server and it takes just
a minute (aprox.).
Could you give me advice on troubleshooting it?
Thanks in advance.
Carlos.
