Hello, I have a ZFS raid1 from 2 drives to 1TB <WDC WD1001FALS-00E8B0 05.00K05>. Recently, my system OS: FreeBSD 8.2-RELEASE has crashed, with kernel panic: -------------------------------- panic: solaris assert: ss->ss_end >= end (0x6a80753600 >= 0x6a80753800), file: /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/space_map.c, line: 174 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

Can anybody tell me what is it? -------------- next part -------------- An HTML attachment was scrubbed...
