vinum raid5 panics
I just put together a 5 disk raid5 system using vinum on 4.0 from last Wed., and I am experiencing random panics. I can force the panic by working on the filesystem, but sometimes just having it mounted kills the machine. I compiled a debug kernel, and got a crash dump, but I am not an expert at debugging crash dumps, so any advice would be appreciated. Instead of dumping out fifty pages of kernel and hardware config could anyone who is working on this let me know what would be helpful...

I bet you see the same problem as others do In my book vinum on 4.0 is plain broken. If its an option for you, vinum under -current works better but its still far from stable. BTW do you have a fxp netcard pr chance ?? -Søren To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Re: vinum raid5 panics
Same here, I'm running 4 disks RAID-0'd under 4.0-current for Diablo, and it's running fine. Haven't updated anythign to RAID-5 support yet.

To be a little more positive, are these problems being addressed, and is there any way that I can help? BTW do you have a fxp netcard pr chance ?? No, rl0.

I bet you see the same problem as others do In my book vinum on 4.0 is plain broken. I think that's overstating the case. We've seen some problems with Vinum RAID-5 on IDE drives, but I can't reproduce them here. Søren's looking at the problem. As Søren also indicates, the fxp board seems to aggravate the problem. If its an option for you, vinum under -current works better but its still far from stable. I believe we have exactly the same problems in -CURRENT. It's also currently not being maintained.
