[linux-lvm] cleaning archive directory

[linux-lvm] cleaning archive directory

[Olle Liljenzin]

Is the directory /etc/lvm/archive supposed to be cleaned up manually or 
should it be done by some tool?

I'm asking since the directory has grown to about 100MB on one of our 
machines.

I find parameters like 'retain_min' and 'retain_days' in the file 
/etc/lvm.conf, which I thought was indicating some kind of automatic 
cleaning tool or process. But I can't find any max values for how many 
files or how many days the files should be stored and it looks like the 
archive files are never deleted.

They should normally get cleaned up automatically.

The parameters apply to each VG separately, and the checks are made
whenever a new archive file is written for that VG.
(So backups of old VGs won't be deleted.)

Default keeps backups for at least 30 days and won't delete any unless 
that leaves at least 10 backups of that VG.

Hi,

Thanks for the answer.

Then I think the clean up is broken in RHEL4.

I have filed a bugzilla for it if someone wants to fix it some day.

Yep: A fix to a related problem several months ago introduced this
new problem.

I've put a fix into CVS; it's still not perfect because it still 
uses the modification time in the filesystem rather than opening
each file and checking the creation time within the archive.
