We have a server (opensolaris 2008.05 upgraded to snv_90) that recently stopped responding. Trying to SSH in would fail with a fork, no space left error. Maybe a runaway mem leak, not sure, so we hard rebooted... Now the kernel panics on boot with the following message: panic[cpu0]/thread=ffffff00077ddc80: assertion failed: 0 == dmu_buf_hold_array(os, object, offset, size, FALSE, FTAG, &numbufs, &dbp), file: ../../common/fs/zfs/dmu.c, line: 451 ffffff00077dd8a0 genunix:assfail+7e () ffffff00077dd950 zfs:dmu_write+15c () ffffff00077dda10 zfs:space_map_sync+27a () ffffff00077ddab0 zfs:metaslab_sync+24f () ffffff00077ddb10 zfs:vdev_sync+b5 () ffffff00077ddbb0 zfs:spa_sync+229 () ffffff00077ddc60 zfs:txg_sync_thread+226 () ffffff00077ddc70 unix:thread_start+8 () skipping system dump - no dump device configured rebooting... The server has a single zfs root pool with two mirrored drives. Trying to "zpool import -f -R /mnt/rpool rpool" with the 2008.05 livecd or the latest 2008.11 preview livecd causes the server to hard reboot immediately. Anyone have any ideas? I''d appreciate any help and thank you in advance. -- This message posted from opensolaris.org
