This question is related to recovery (fsck and xfs_repair) and journalling. I powered off (improper shut down) the system when the IO was undergoing on mounted EXT4 filesystem. After that I powered on my machine and then used fsck on the unmounted filesystem. fsck recovered it. There are 2 things which I want to confirm: 1. Firstly fsck replays the journal for any unfinished inconsistent writes. 2. Secondly it checks/repairs the other filesystem corruption. Correct my understanding if wrong. Consider the above scenario for XFS as well. In XFS, i need to mount the filesystem, and this automatically replays the journal. After this I again unmount the filesystem and run xfs_repair. But in EXT4, i have to run fsck mandatorily before mounting my filesystem. Please confirm my understanding. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
