Weird kernelpanic when harddrive timeouts

[blodan]

Hi!

I have a harddrive I use for storage (/storage2 in the attached photo). Sometimes it decides to timeout. It'd a WD 2.5 TB green so what I have read this is normal.

But my problem is that FreeBSD is panicing when this happens and I have no system software running on this disc so, to me, it seems a bit strange. Shouldn´t FreeBSD be able to handle this and just put some errors in the syslog?

Or do I have to change some sysctl for this to work properly, I have been googling about this but it seems no one else is having this issue.

I have a fairly up-to-date install so it's probably not a bug problem.

Many of the bugs related to IO and kernel panic has been fixed this year. I highly recommend upgrading to 8.2 STABLE or the release candidate of FreeBSD 9

There doesn't need to be any system software on it. Merely having it mounted is enough. You get the same kind of issue if you unplug a mounted USB memory-stick.

As Olav noted there has been some work done on FreeBSD to make it a little more resilient.

Thanks guys, updating to 8.2 seems to have helped. I´ll stay there for now, going for 9 on a production server is a tad too risky for me
