ssh relation to bad disk

UniRock — Tue, 13 Apr 2010 03:11:15 GMT

Hi All,

Details:
OS: hpux 11.0
Issue: Cannot ssh into the box
Addtional info: One of the root disk which is mirrored went bad (Rest everything is fine)

I got to know from *somewhere* that this might be related to bad root mirror disk. So replaced it first. Then ssh started working fine.

Just wanted to know what is the connection between ssh and root mirror disk??

Thanks a lot..

Well I do not see nay relation of bad disk with ssh.

Any other observation on that time would be necessary to get lil into the issue.

It's not obvious, unless the ssh software or data files were on that bad sector?
Or it had to read from disk because it wasn't in memory?

May be....but then the other mirror disk was working fine.

>> try kill old ssh pid and start it again
Tried but those never got killed.
As of now, issue is resolved by replacing the disk..Dont know why?? :(

Hello,

>Just wanted to know what is the connection between ssh and root mirror disk??

If the ssh user's home directory resides on the root disk, maybe the public/private key file had some problems. This could drive to this kind of troubles.

i suppose disks are mirrored so it does not matter where file exist, both would be having same content.

Hello,

>i suppose disks are mirrored so it does not matter where file exist, both would be having same content.

They would have the same content only if the disks would be in synchronized state.

What if somehow one key changed, and the system managed to actually save partially the file on only one HDD, just before the other disk went bad?
