Hello, To cut to the chase, I have a procstat -kk -a captured during a livelock for you here: http://tog.net/freebsd/zfsdeadlock-storage1-20130703 The other relevant configurations I could think of to show you are available within that http://tog.net/freebsd/ directory. If you want any additional information that I haven't given here please let me know! This is a FreeBSD 9-STABLE AMD64 system currently at: r250777: Sat May 18 17:41:39 EDT 2013 I didn't see too many relevant ZFS-related fixes after that date so am waiting for another round of interesting commits to update again. Unfortunately, this system has been livelocking on average about once every 7-14 days. Its lot in life is a ZFS storage server serving NFS and istgt traffic. It has 32GB of RAM and is an 8-core 2.6GHz Opteron 6212. The zpool looks like this, it has eight 1TB SAS drives and two SSDs being used for log and cache. pool: storage1 state: ONLINE status: The pool is formatted using a legacy on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on software that does not support feature flags. scan: scrub repaired 0 in 6h4m with 0 errors on Sun Jan 6 06:39:38 2013 config: NAME STATE READ WRITE CKSUM storage1 ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 da0 ONLINE 0 0 0 da2 ONLINE 0 0 0 da4 ONLINE 0 0 0 da6 ONLINE 0 0 0 raidz1-1 ONLINE 0 0 0 da1 ONLINE 0 0 0 da3 ONLINE 0 0 0 da5 ONLINE 0 0 0 da7 ONLINE 0 0 0 logs mirror-2 ONLINE 0 0 0 da8p2 ONLINE 0 0 0 da9p2 ONLINE 0 0 0 cache da8p3 ONLINE 0 0 0 da9p3 ONLINE 0 0 0 errors: No known data errors -- TerraNovaNet Internet Services - Key Largo, FL Voice: (305)453-4011 x101 Fax: (305)451-5991 http://www.terranova.net/ PGP: 50091B3D ---------------------------------------------- Life's not fair, but the root password helps.
