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

[Toshiyuki Ishimura]

Ok. I try to gather verbose rdiff log and unfsd log with strace.

And actual command, host and directory name as follow.
server01:~$ mkdir hoge /mnt
server01:~$ touch hoge/foo
server01:~$ (cd hoge; ln -s foo bar)
server01:~$ mount -t nfs -o soft,rw,intr server04:/var/backup /mnt
server01:~$ rdiff-backup hoge /mnt

After error, remote directory as follow
server04:~# ls -la /var/backup/
total 12
drwx------  3 root root 4096 Jul 25 03:49 .
drwxr-xr-x 16 root root 4096 Jul 25 03:05 ..
drwx------  3 root root 4096 Jul 25 03:49 rdiff-backup-data
lrwxrwxrwx  1 root root    3 Jul 25 03:49 rdiff-backup.tmp.1 -> foo

It seems that rdiff or unfsd fail to rename "rdiff-backup.tmp.1" to "bar".
