Copying ocfs files over NFS

Vipulinux — Sat, 16 Dec 2006 09:04:57 GMT

hi
I am trying to copy database files stiing on ocfs file system to another server using NFS.

when i give the copy command after mounting the ocfs over nfs it does not copy anything in the sub directories, also lot of errors like NFS Stale file etc etc.

Can someone point where I am going wrong.

Thanks

Is the nfs share still being exported? Try running $ /usr/sbin/showmount -e to see if the nfs share is really there.

You could also try nfsstat -s on server and
nfsstat -c on client side to see NFS statistics.

If so, you might want to see if you can manually mount and remount the share. Failing that, you may need to reboot the server to eliminate the stale file error.

Best,
Bryan

NFS Stale normal means NFS has problems somewhere. Problems exists Not in the specific file types you want to copy

OCFS is the Oracle Clustered FileSystem. You need file utilities which are capable of direct io (O_DIRECT) to copy a database from a ocfs filesystem.

The RPM's for direct io enabled standard Linux utilities like cp, tar, etc. can be downloaded from the Coreutils project. Please see http://oss.oracle.com/projects/ocfs/ and http://oss.oracle.com/projects/coreutils/files/
