Subject: deadlocked xfs
Date: Thu, 10 Jul 2008 21:33:11 -0500	[thread overview]
Message-ID: <4876C667.608@sandeen.net> (raw)

while running fs_mark:

fs_mark -d /mnt/test -D 256 -n 100000 -t 4 -s 20480 -F -S 0

which runs 4 threads making 20k files,things got stuffed up in the log,
see sysrq-w output at:

http://sandeen.fedorapeople.org/xfs/deadxfs

2 threads down this path:

 [<ffffffffa03c89f5>] :xfs:xlog_state_get_iclog_space+0x83/0x187
 [<ffffffffa03c8c1a>] :xfs:xlog_write+0x121/0x486
 [<ffffffffa03c9043>] :xfs:xfs_log_write+0x2a/0x50

this is on a 4 cpu AMD.

I made the fs with:

mkfs.xfs -dsize=1t,agcount=32 -l lazy-count=1 -f /dev/sdb

and mounted with:

mount -o nobarrier,logbsize=256k,logbufs=8,inode64 /dev/sdb /mnt/test

has this been seen before?

Thanks,

-Eric
