Hello all,

maybe you have seen my "NAS326 problem" discussion.

What I want to ask is this:

after some days my NAS326 was working for one hour unexpectedly.
I tried to backup, but stopped at 5% of the data. Then stopped again - "No Volume"

What I want to ask, how can I run e2fsck on that faulty disk ?

sd(a,b) 1,2,3 : not mounted

running e2fsck always says:
/dev/sd(a,b)1,2,3 is in use.
e2fsck: Cannot continue, aborting.

fuser (a tool is not part of Linux on NAS326), so I tried to use lsof command.
But I am not sure how to list only processes that are using these disks with lsof

Any advice pls ?

And is even reasonable to run fsck or e2fsck on HDD which is part of NAS326?
