Re: [rdiff-backup-users] Stale NFS file handle error with unfsd and symbolic file

[Toshiyuki Ishimura]

Sorry, I have report by mistake.

Rsync failed to copy files as follow.
local:~$ rsync -a -x --delete hoge/ mnt
rsync: chown "mnt/bar" failed: Stale NFS file handle (116)
rsync error: some files could not be transferred (code 23) at 
main.c(977) [sender=2.6.9]

It is doubtful whether rdiff-backup is wrong.
So, I try to chown remote symbolic file.

remote:/tmp# touch foo
remote:/tmp# ln -s foo bar
Then back to local.
local:~# mkdir hoge mnt
local:~# mount -t nfs -o soft,rw,intr remote:/tmp mnt
local:~# chown -h nobody mnt/bar
chown: changing ownership of 'mnt/bar': Stale NFS file handle

"-h" option in chown changes ownership symbolic link itself.
This shows that rdiff-backup has no error.
Maybe, unfsd cannot change ownership of symbolic link (lchown system call).

Thanks, many helps.
