I rebooted my server 20hrs ago, and had 20gig of free space ... now I'm
down to 4.6gig ...
venus# df -t ufs
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/amrd0s1a 103777974 90836532 4639206 95% /
Before I rebooted it 20hrs ago, it had drop'd down <500Meg, and after the
reboot, pop'd back up to 20gig ...
I can't seem to find where 16gig of disk space is being used though, but,
for instance, I had 12gig of files in /var/vmcore (from crash dumps) that
I removed, which should have increased me to 16gig free, but I'm still at
4.6gig and drop'ng ...
The system isn't particularly busy:
venus# iostat 5
tty amrd0 cpu
tin tout KB/t tps MB/s us ni sy in id
1 116 0.00 0 0.00 32 0 28 1 40
1 452 4.29 343 1.43 39 0 52 0 9
0 225 5.21 258 1.31 32 0 47 1 21

1 32 4.81 261 1.23 16 0 51 1 32
And the drive is 7x18gig in a RAID5 configuration ..
OS is 4.8-RC FreeBSD 4.8-RC #38: Tue Mar 4 22:43:18 CST 2003 with a patch
from Tor Egge to fix a problem with how vnodes are kept track of and
reclaimed/reused ...
I've tried doing a 'sync', figuring that maybe it would force all
outstanding writes to the drive, but that seems to make no difference
either ...
I'm doing a du right now to see if I can see anything large out of the
ordinary, but is there any way (maybe using lsof?) of finding out what,
if any, processes are holding open a large file?
