Andreas Dilger a2292f8a51 tune2fs: reset MMP state on error exit ... If tune2fs cannot perform the requested change, ensure that the MMP block is reset to the unused state before exiting. Otherwise, the filesystem will be left with mmp_seq = EXT4_MMP_SEQ_FSCK set, which prevents it from being mounted afterward: EXT4-fs warning (device dm-9): ext4_multi_mount_protect:311: fsck is running on the filesystem Add a test to try some failed tune2fs operations and verify that the MMP block is left in a clean state afterward.
