I cannot find the answer in the on disk specification or anywhere else.
Are the vdev in a mirror block by block copies ? I mean is block 10013223
on on device the same as block 10013223 on the other devices in a mirror vdev.
Off course only after that block has ever been used by zfs, I know blocks that
have
never been used contain unspecified data.
What happens if a block on one devices get corrupted because of a media error ?
Will zfs
just allocate another block on that device and write the repaired data to that
new block ?
Where can I find more information on how zfs does this ?
