Hi guys,
I have a pool made with three luns striped.
After some scsi retryable messages, happened during a storage
activity, zpool status start to report one checksum error on one
file only.
The zpool scrub find it but don't solve it, and when I try to read
the file, I get an I/O error.
Again, when I try to copy the file, I get only some bytes copied,
and then stops, I mean this is because the next block is in error...
However, I'd like to do some check on this file, especially since I
am not convinced that the lun is bad and the file corrupted...
Is there a way to force zfs to give me the whole file so I can
compare it to my backup?
Is there a way to get zfs to give more specifics on the checksum
issue (i.e. which block, where in file, etc.)?
I wrote a few blog entries on this sort of thing.
