Hi there,
I have a zpool attached via firewire, and it seems it got corrupted in the last month -- zpool scrub identifies checksum errors.
status -v lists two files as being corrupt, named x/<0x0> and x/<0x3>. Any advice how to deal with this? I'm happy to just delete the corrupted objects, if I knew which ones they were. Besides the number, no identification is given. Anything I can do with e.g. zdb to help me along?
When issuing a zfs send on the filesystem in question, a kernel panic ensues. That is probably not what should happen. Happy to help you debug this, before cleaning up my ZFS. Here what I have so far, please advise if any more information is useful to you:
