If you use fsck, be sure to specify filesystem type as ext3. And if you are just mounting it without fsck, EXT3 FS writes "recovery complete" message using kernel printk(). You have to use dmesg program to display it on your console. On boot before klogd and syslogd are started, such printk()s are usually displayed on the console. That doesn't necessarily happen after boot has completed. I tried to reproduce this twice in data=ordered mode. On first attempt I used fsck to replay the journal. Here is output of that attempt: # losetup -e AES128 /dev/loop0 /root/zz loop: loaded (max 8 devices) Password: # fsck -t ext3 -f /dev/loop0 fsck 1.27 (8-Mar-2002) e2fsck 1.27 (8-Mar-2002) /dev/loop0: recovering journal Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/loop0: 12/102400 files (0.0% non-contiguous), 7322/102400 blocks On second attempt, I just mounted it and EXT3 FS replayed the journal. Here is output of that attempt: # mount -t ext3 /root/zz /mnt666 -o loop=/dev/loop0,encryption=AES128 loop: loaded (max 8 devices) Password: kjournald starting. Commit interval 5 seconds EXT3 FS 2.4-0.9.17, 10 Jan 2002 on loop(7,0), internal journal EXT3-fs: recovery complete. EXT3-fs: mounted filesystem with ordered data mode.
