Input/Output error and loosing network...

Hello, big pb here....

- WHile copying some file from Windows on /mnt/HD_a2/, I have been disconnected (unable to access the dns323 anymore ==> had to reboot).

- "ls" on the concerned directory gives input/output errors....

- Tried to perform fsck procedure following http://www.inreto.de/dns323/fsck/

- Every time I run e2fsck on the /dev/sda2 partition , I am disconnected (from putty) after 1 or 2 minutes (have to reboot).

So I cannot fix my errors on the disk....

Any idea ??

Re: Input/Output error and loosing network...

You cannot e2fsck a mounted partition.  You may want to try ffp reloaded (see wiki) to get to a point to do this.

I thought the procedure described in http://www.inreto.de/dns323/fsck/ allow to perform e2fsck on unmounted partition ?

Yes, that has the instructions for ffp reloaded; I did not read all the way down the page of the link.

Did it pass the tests for swap, RAID, etc?

I just tried again with 2 telnet consoles :
- first one running e2fsck
- second one running top

after few minutes,
- the first console diseapears (e2fsck crash ??)
- the second console shows no more e2fsck running and init process is taking 100% of CPU...

Re: Input/Output error and loosing network...

Did you happen to run out of swap space? Is swap configured propperly?  I do not know too many ways that e2fsck will crash, but swap is one.  I am not an expert on the program.

Thank you for your answer. I think swap is not a problem because I ran e2fsck on the second drive /dev/sdb2 and it went ok through the end. The problem is only with the first drive /dev/sda2.

Maybe there is an hardware error on the disk ??

Re: Input/Output error and loosing network...

You can always do what I do.  Put ffp on the second disk, power down the unit.  Pull th first disk (right bay) and boot the unit with only the second disk in.  It will load that disk as /dev/sda2.  Hot insert the first disk and it will pick up as /dev/sdb2, but will not be mounted.  Run e2fsck on it.  Once that is done, do a "do_reboot" and the unit should come back up normal.
