So you are experiencing slow I/O which is making the deletion of this clone and the replay of the ZIL take forever. It could be because of random I/O ops, or one of your disks which is dying (not reporting any errors, but very slow to execute every single ATA command). You provided the output of 'zpool iostat' while an import was hanging, what about 'iostat -Mnx 3 20' (not to be confused with zpool iostat). Please let the command complete, it will run for 3*20 = 60 secs.
Also, to validate the slowly-dying-disk theory, reboot the box, do NOT import the pool, and run 4 of these commands (in parallel in the background) with c[1234]d0p0: $ dd bs=1024k of=/dev/null if=/dev/rdsk/cXd0p0 Then 'iostat -Mnx 2 5' Also, are you using non-default settings in /etc/systems (other than zfs_arc_max) ? Are you passing any particular kernel parameters via GRUB or via 'eeprom' ? On a side note, what is the version of your pool and the version of your filesystems ? If you don't know run 'zpool upgrade' and 'zfs upgrade' with no argument. What is your SATA controller ? I didn't see you run dmesg. -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
