I am running into issues with ZFS where perl, specifically amavisd
running spamassassin creates unbelievably large files, as in files 100x
the size of the hard disk.
My setup is a host run a dozen jails. The host is amd64 FreeBSD
8.1-RELEASE-p1 #6 as of Thu Sep 30. The jails are running 8.0 release
as I have not yet upgraded them. This setup has been very stable till I
introduced ZFS. Below is the zpool setup:
zpool status
pool: m1012
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
m1012 ONLINE 0 0 0
mirror ONLINE 0 0 0
ad10 ONLINE 0 0 0
ad12 ONLINE 0 0 0
Last night I moved six jails from my UFS+S RAID5 file system to the new
ZFS file system. Since then perl occasionally runs at 100% disk usage
accessing files in /var/amavis/.spamassassin Here is the current
directory listing:
ls -l .spamassassin
total 13352131
-rw------- 1 vscan vscan 684032 Oct 15 12:02 auto-whitelist
-rw------- 1 vscan vscan 40 Oct 15 12:37 bayes.lock
-rw------- 1 vscan vscan 1294336 Oct 15 12:38 bayes_seen
-rw------- 1 vscan vscan 4227072 Oct 15 12:38 bayes_toks
-rw------- 1 vscan vscan 553184002048 Oct 15 12:38
bayes_toks.expire3515
-rw------- 1 vscan vscan 140743122878464 Oct 15 12:14
bayes_toks.expire97254
The last file is 140TB which is pretty good sized for a 1TB disk. Disk
compression is OFF. du -hs reports 13G int the .spamassassin directory.
Any thoughts?
