Thanks Max and Chris. I don't really want the problem to occur again, of course, but I'll be prepared if it does. On Wed, Dec 3, 2008 at 6:46 PM, Chris Siebenmann <[EMAIL PROTECTED]> wrote: > You write: > | > If keyboard input is not getting in, your machine is probably wedged > | > at a high le

Thanks - however, the machine hangs and doesn't even accept console input when this occurs. I can't get into the kernel debugger in these cases. I've enabled the deadman timer instead. I'm also using the automatic snapshot service to get a look at things like /var/adm/sa/sa** files that get o

I think my problem is actually different - I'm not using iSCSI at all. I will update if I find otherwise. And yes, I do think there is support available for OpenSolaris now: Blake On Wed, Dec 3, 2008 at 9:32 AM, Tim <[EMAIL PROTECTED]> wrote: >

I'm having a very similar issue. Just updated to 10 u6 and upgrade my zpools. They are fine (all 3-way mirors), but I've lost the machine around 12:30am two nights in a row. I'm booting ZFS root pools, if that makes any difference. I also don't see anything in dmesg, nothing on the console ei

Thanks for the reply and corroboration, Brent. I just liveupgraded the machine from Solaris 10 u5 to Solaris 10 u6, which purports to have fixed all known issues with the Marvell device, and am still experiencing the hang. So I guess this set of facts would imply one of: 1) they missed one, o

I have a PC server running Solaris 10 5/08 which seems to frequently become unable to share zfs filesystems via the shareiscsi and sharenfs options. It appears, from the outside, to be hung -- all clients just freeze, and while they're able to ping the host, they're not able to transfer nfs or
