[Bug 1222429] btrfs does not know norecovery since 6.8

The point of r-o mounting is to keep the FS "as is" (also/or ideally with noatime as that may also change something).

Please note that the 'ro' mount option semantics does not prevent writes to happen before the mount is finished, the writes are prevented from user space. IOW, log replay can still happen with 'ro' mount so you need some sort of log replay preventing option, or to temporarily make the block device read-only (blockdev --setro). -- You are receiving this mail because: You are on the CC list for the bug.
