because btrfs does mount this partition '''readonly''' when it detects corrupted blocks. | |||
Now you have to investigate WHY a checksum of a btrfs block says it is corrupted. | |||
* In some cases the underlying device may beginn to fail ! => replace it (consider using RAID) | |||
* In other cases a corruption may have happened even before the block had been written to disk | |||
