It looks suspiciously like a CIFS lock. There is a hidden command "lock_dump -f" which is available after doing "rc_toggle_basic". It shows all the cifs locks.
The reason the files are locked even for root is that SMB locks are mandatory. We are following NT semantics. It is not perfectly clear that you would always want to strictly follow NT semantics in all cases, and we are looking at addressing that issue.
If you can do your backups from snapshots you will avoid the problem of files locked by CIFS clients.

A filer of ours (ast-h-dcf04) has NFS exported as root to a system named "nimbus". The filer is giving permission denied messages when trying to access some files as root. This is causing backups to fail for this file (and a few others). Anyone seen this type of behaviour?:
[nimbus] ~ 103> sudo file "/data/ast-h-dcf04/ast-h-dcf04-1/kfackler/ups/UPS Server Backup.doc" /data/ast-h-dcf04/ast-h-dcf04-1/kfackler/ups/UPS Server Backup.doc: cannot open: Permission denied
Other files in the same directory can be accessed, and they have identical permissions as this one:
-rwx------ 1 kfackler nt 19968 Jul 8 09:10 UPS Server Backup.doc*
I thought maybe this user had it locked in CIFS, but:
ast-h-dcf04> cifs sessions kfackler
users shares/files opened
MA106734 (ACCT02\kfackler - kfackler) {home_dir}
Is there a way to list the files locked by CIFS on a filer? And even if it were locked - why can't root do querires on the file, or back it up?
This filer is running 5.3D14. Hopefully I'm missing something very obvious here....
Thx, Graham
