Hi guys. I'm new to the forums, but not to the DNS products; I have a 1.5TB DNS-323 with RAID0/EXT3 filesystem for my important files, and an 8TB DNS-343 with a JBOD/EXT2 filesystem for media file storage.
I took a power hit while moving some files to the DNS-343, and it works fine, but I'm seeing 'input/output error' for the inodes of the files I was in the process of moving at the time; Windows says the files are in use, and from the ssh prompt (I have ffp installed, ssh configured) I can't remove the files, with an error message that the system cannot stat the file due to input/output errors.
I ran e2fsck with the -n flag, and it found issues with those files, but I can't run it with the -y flag to fix the errors with the volume mounted. I'm not able to unmount the volume because I'm ssh'd in, and 'fu' shows ssh using the volume (/ffp is mounted on that volume).
I *think* what I need to do from the research I've done on this excellent site and others is configure telnet to run from a bootable USB drive, boot from that USB stick and umount the volume and run my checks. I'm a little lost on where to start or how to configure this. Can somebody point me in the right direction? Is there a HOWTO on this? If not, I volunteer to document the process and create one as I go through this process.

If you haven't managed to do it already...
Because the 343 has a different kernel, using fonz's fsck module (http://inreto.de/dns323/fsck) doesn't work.
The way I did it was to copy my ffp folder to USB so I could boot from there - meaning I can umount all my HDDs and go nuts.
1) To mount your usb drive - http://dns323.kood.org/forum/viewtopic. … 653#p30653 (do test to make sure you can reboot with it)
2) once rebooted and usb drive still working, copy your ffp from /mnt/HD_a2/ffp to /mnt/usb/
cp -a /mnt/HD_a2/ffp /mnt/usb
3) to boot ffp from usb
create a folder /mnt/HD_a2/.bootstrap
# mkdir /mnt/HD_a2/.bootstrap
copy /sys/crfs/driver/usb-storage.ko (make sure to use the one stored on system already as it's tailored for 343 - thanks fonz!) to /mnt/HD_a2/.bootstrap
# cp /sys/crfs/driver/usb-storage.ko /mnt/HD_a2/.bootstrap
download setup.sh (source: http://dns323.kood.org/forum/t3203-setu … -root.html) and place it into /mnt/HD_a2/.bootstrap
Edit setup.sh for your system. The two things you'll need to change are:
which usb-storage module to use
USBMODULE=${INTERNALHD}/.bootstrap/usb-storage.ko #USB storage module locationshould be
cp /sys/crfs/driver/usb-storage.ko /lib/modules/ #copy USB storage module to VRAM so that physical disks can be unmounted USBMODULE=/lib/modules/usb-storage.ko #USB storage module location
and which device is your usb - the 343 can have 4 HDDs as opposed to the 323's 2.
USBFFPPART=/dev/sdc5 #USB partition containing the /ffp system
should be
USBFFPPART=/dev/sde1 #USB partition containing the /ffp system
(or whatever dev/sd<letter>1 your usb drive is)
4) Last but not least, create the dummy file /mnt/usb/.ffp-usb
touch /mnt/usb/.usb-ffp
reboot!
then you can umount and e2fsck to your heart's content.

THANK YOU for those detailed instructions! I did get past my original issue, but will be keeping this as a sticky note for future use!
