should btrfsck fix a bad superblock?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I (intentionally) used wipefs -a on a device with a btrfs. As expected
btrfs check doesn't recognize the device as having a btrfs volume
anymore.

Slightly surprising that it doesn't mention other intact supers are found.

Most surprising that options -s1 --repair doesn't fix it.

I thought maybe it's intentional, only with explicitly bad magic, and
I'd get different results if it were zero'd. So I zero'd it and I get
the same results. s0 superblock isn't repaired with --repair.

Bug?

Of course I can fix it with echo+dd.
