Hello,

I have a problem after resilvering. It is pernament error that occurred after replacing the disk. Resilvering not performed in its entirety. zpool status -v returns:
Code: 
 pool: storage
 state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

errors: Permanent errors have been detected in the following files:

        storage/daneprojektowe:<0xd256>

After the zpool clear tank problem still exists. I do not know how to finish a fully resilvering and get rid of this error.

Best regards and please help

Thank you for your reply, I did the exact same thing Sebulion after writing this post. It worked :e Thanks and best regards.
 
In this case you were lucky, but by using raidz1 you will not have a redundant copy of your data if you're resilvering. There is however always a second copy of master/head checksum, so your files in this case are 100% consistent.

I highly recommend everyone to always use at least raidz2 and have backup.
