Hi all:
I have a FBSD 5.2.1 box running vinum. 7 *160gb drives in a raid5 array.
I can post specific errors and logs and such later, i'm away from the box right now --- anybody have any thoughts ?
How about http://www.vinumvm.org/vinum/how-to-debug.html?

freebsd 5.2.1
specific problems:
1) a post-mount FSCK causes a kernel panic
2) an FSCK from single user mode errors with "cannot allocate xxxxxxxx bytes for inphead"
3) in single user mode, the array will mount and do a small fsck - recalculate the superblock, and then allow me to traverse the array. When i try to access files on the array, i get an error :
"null rqg"
zero source changes

Vinum log extract:
A few days ago, the array was "mucked" -- i saw one of subdisks was down...here's the log from that incident
2 Mar 2005 21:46:22.721677 *** vinum started *** 2 Mar 2005 21:46:25.871262 list 2 Mar 2005 21:46:28.935388 start 2 Mar 2005 21:46:31.153046 list 2 Mar 2005 21:46:46.616922 start raid5.p0.s6 2 Mar 2005 21:46:49.949753 quit
Other than that - there is nothing of particular note in the vinum history - the entire file can be supplied if need be.
Kernel dumps will be supplied later today or tomorrow - i'm not going to load up and dump the raid5 array for fear of further corruption. I'm gathering hardware to make an image of it onto a hardware raid5 controller and see if i can salvage it from there.
If you need more, say the word. The kernel dumps will come soon
