Hi Folks, We have a zfs fileserver running 9.0-RC1 which appears to have locked up in a manner similar to the "Damanged directory on ZFS" thread. It started after a zfs snapshat which appears to have hung. At that point, an "ls" command on a directory which is either empty or contains only other directories works correctly. An "ls" on a directory containing a file will hang. The OS is installed on an OCZ card with UFS, ZFS is only used for the data volume. The following information is rather large and is available here: http://people.freebsd.org/~jwd/tx_sync_done.html On the page: zfs snapshot (which appears to have caused the issue) an ls that works (on empty or directory with only directories) an ls that hangs (directory contains files) zpool history that hangs ps -auxww procstat -kk -a zpool status zfs list df -hl zfs list -t sysctl -a (Very, Very large) uname -a (as below) FreeBSD server1 9.0-RC1 FreeBSD 9.0-RC1 #0 r226607M: Fri Oct 21 11:32:01 EDT 2011 neh@server1:/usr/obj/usr/src.2011-10-21_01.37.40/sys/ZFS amd64 The system is sitting idle at this point if we can provide any additional debugging informtion. Please let me know. Thanks, John
