Re: Still looking for reports of missed directory entries w/ HAMMER
:This machine is pretty much dedicated to backup and file serving.
:- it runs rsnapshot every 4 hours on the problematic filesystem.
:Each rsnapshot run gets files in sequence from 7 different machines and 34
:The target is a 400GB Hammer filesystem on a RAID1 volume (3Ware SATA). This
:filesystem is mounted nohistory.
:Rsnapshot takes a _long_ time to rotate its hourly directory snapshots
:(directory deletion and re-creation, hard-links). My guess would be about 20
:minutes per run for this part.
:Time spent running rsync is quite short in comparison; this filesystem is only
:running at most one instance of rsync.
Ah ha. Ok, I will focus on rsnapshot's directory snapshot rotation
in trying to reproduce this issue.
Note: Just today I committed work to HEAD which allows messed up
directory entries to be removed. They will show up as the fifo
type in an ls (as well as spew warnings on the console), and you
can 'rm' them.
