Today, I had to uncleanly shutdown one of our machines due to an error in 2.6.28.3. Durin the boot sequence, the ext4 partition /home experienced a journal replay. /home looks like this: /dev/mapper/volg1-logv1 on /home type ext4 (rw,noexec,nodev,noatime,errors=remount-ro) Filesystem Size Used Avail Use% Mounted on /dev/mapper/volg1-logv1 2,4T 1,4T 1022G 58% /home Filesystem Inodes IUsed IFree IUse% Mounted on /dev/mapper/volg1-logv1 19519488 8793310 10726178 46% /home The journal replay too quite a while.
