Subject: Deadlock?
Date: Mon, 13 Feb 2012 12:17:28 +0100	[thread overview]
Message-ID: <3125411.WeeEOF8PnR@f209> (raw)

Hi!

I noted some kind of deadlock, where I was not able to write to the raid6, 
while writing to each disk would still work.
This caused many processes to "wait" in d-state, thus making it impossible to 
unmount, cleanly reboot, sync, ...

So I enabled the detection of hung tasks and this deplock option.
After running a 3.2.2 for about 5 days:

I dont know if its a bug or nothing. Or if it has anything to do with my 
problem as there was no hungtask detected and the raid still seems to work.

Can anybody enlight me?! ;)

Markus
