Hello there,I have some problems with my RAID-5 under gvinum since a power outage because of a lightning.
If I mount the volume and the automatic background fsck run, check or rebuild the parity I will get a panic.
Shorthand before the lightning I began to upgrade from 5.4-stable to 6.1-stable. Because of that I ignored the flaws on my data disk and continued the upgrade. The error originated with a 5.4-stable without debugging enabled.
Now the machine has the following running with a dump device configured:FreeBSD titan.home.sumirati.net 6.1-STABLE FreeBSD 6.1-STABLE #0: Sun Jul 30 21:19:10 CEST 2006 [EMAIL PROTECTED]:/usr/obj/ usr/src/sys/GENERIC i386
The stable is from Saturday, 29.07.2006 as of around 22:00 MET from cvsup2.de.freebsd.org.
The message in /var/crash/info.* looks everytime like this:Panic String: kmem_malloc(262144): kmem_map too small: 172404736 total allocated
The dmesg and the vinum configuration is attached. I also attached a backtrace but I think it is not that useful.
I found nothing in the archives about a problem like this. Some PRs are showing kmem_map erros but not with (g)vinum.
My questions are:Is there any know bug or problem with gvinum with rebuilding the parity? and
How can I get back my data? (of course :))I'm in the process of making sure the hardware is ok while dd'ing them to /dev/null.
Thanks a lot for your time Marc
