I would say it is definitely very odd that writes are a problem. Sounds like it might be a hardware problem. Is it possible to export the pool, remove the ZIL and re-import it? I myself would be pretty nervous trying that, but it would help isolate the problem? If you can risk it.I think it is unlikely to be a hardware problem. While I haven't run any destructive testing on the ZFS pool, the fact that it can be read without error, combined with ECC throughout the system and the panic always happen- ing on the first write, makes me think that it is a software issue in ZFS. When I do: zpool export data; zpool remove data da0 I get a "No such pool: data". I then re-imported the pool and did: zpool offline data da0; zpool export data; zpool import data After doing that, I can write to the pool without a panic. But once I online the log device and do any writes, I get the panic again. As I mentioned, I have this data replicated elsewere, so I can exper- iment with the pool if it will help track down this issue.
