RaidFrame Raid-1 problem (can't ditch a failing disk)
I have a strange problem replacing a drive from a RAID-1 RaidFrame set.
Here's some info:
# uname -mrs
NetBSD 5.0_STABLE i386
# raidctl -s raid0
/dev/sd0a status is: failed. Skipping label.
Component label for /dev/sd1a:

Clean: No, Status: 0
sectPerSU: 128, SUsPerPU: 1, SUsPerRU: 1
Queue size: 100, blocksize: 512, numBlocks: 143638784
RAID Level: 1
Root partition: Yes
Last configured as: raid0
Parity status: DIRTY
Reconstruction is 100% complete.

Adding to "monitor" list.
Feb 26 00:43:04 thoth smartd: Device: /dev/sd0d, SMART Failure:
HARDWARE IMPENDING FAILURE TOO MANY BLOCK REASSIGNS
So we got a bad disk and I have to change it out. So I did the following:
o failed the component with "raidctl -f /dev/sd0a raid0"
o shut down
o replaced the disk
o Now the system panics right after raidframe initializes. Sorry
I don't have the exact messages but its all raidframe stuff.
Maybe I'll have to take a photo or something. "reboot 0x104"
didn't seem to work.
o power off
o replace the "bad" sd0
o machine boots as normal
So what gives? I verified that I'm removing the correct disk. No
question; the hardware agrees, the LSI Logic bios display agrees and the
scsibus/devices all agree that I'm removing the correct drive.
I also tried removing the drive and not replacing it with a new one.
Still no luck there.
Any help would be great!
