What command can tell me the last time that a filesystem was fsck'd? A date would be nice, but I'd settle for the mount count since the last fsck.

I've looked all around for this in fsck*, lsattr, and stat, and I don't see it.

tune2fs -l gives you that information for ex.

sudo tune2fs -l /dev/sda1 | grep "Last checked"

  • this will only work on ext2/ext3/ext4 filesystems. – Jens Timmerman Dec 20 '13 at 9:43

You can use tune2fs to get the information

tune2fs -l /dev/devicetocheck | grep "Last Checked"

Similarly you can get the mount count

tune2fs -l /dev/devicetocheck | grep "Mount Count"

Apart from tune2fs -l, dumpe2fs will also give you this information:

dumpe2fs /dev/sda1 | grep "Last Checked"
dumpe2fs /dev/sda1 | grep "Mount Count"

Thanks everyone! And for reiserfs I found that debugreiserfs shows the mount count and last fsck run date.
