[zfs-discuss] Thumper wedged somewhere in ZFS

2008-07-09 Thread Ceri Davies
Forwarding here, as suggested by chaps on storage-discuss. Just to clarify, I was running filebench directly on the x4500, not from an initiator, so this is probably not a COMSTAR thing. Ceri -- That must be wonderful! I don't understand it at all.

[zfs-discuss] zpool dumps core with did device
