After a reboot on 4.8 I ended up with a degraded raid 5 partition...
The only thing special about my setup is.... 4944 drives spread over 3 channels,
running SMP kernel.....
One sub disk was down and the and the drive was referenced... in scouring the
mailing lists I saw where a referenced disk means you have referenced a
non-existent drive - I read this as one vinum didn't think was defined.. in my
case it was drive29 --> /dev/da29s1e
I don't know how this got referenced !!! It's been reboot many times and this has
not happened.
So I boldly created a config file for vinum and re-created the drive.....
--- config file ----
drive drvie29 device /dev/da29e
--- end ----
but I still can not start the sub disk.....
(root at jammin) /home/staff/mikej# vinum start raid5-1.p0.s15
Can't start raid5-1.p0.s15: Drive is down (5)
(root at jammin) /home/staff/mikej#
Here is what vinum thinks...... Do I rm the sub disk and re-create it?????
Will this kill my raid-5 partition ??
Thanks !!
