# blockdev --getsize64 /dev/sdb2 /dev/sda2 999131127296 999131127296 Since getsize64 returns bytes and not sectors, I suppose it would need to be aligned to 1024 by the least? 999131127296 / 1024 = 975713991,5 So it's not. > If so, "btrfs rescue fix-device-size" should handle it pretty well. I guess this needs to be done with the fs unmounted? Anything to consider since I have RAID1 (except from running it on both devices)? Also, it's a bit strange that this error occurred never before (though the btrfs-restore manpage says the kernel would check for this since 4.11). It would further be nice if btrfs-check would warn about this.
