hi,

after my -current/i386 desktop hung for the 6th time in 3 days (serial
console, break to ddb impossible, uptime < 2 minutes after the
previous hard hang), raidframe was confused about the status of my
mirror components:

Hosed component: /dev/wd6a
raid0: Component /dev/wd4a being configured at row: 0 col: 0
         Row: 0 Column: 0 Num Rows: 1 Num Columns: 2
         Version: 2 Serial Number: 444444 Mod Counter: 1026742437
         Clean: No Status: 0
/dev/wd4a is not clean!
raid0: Ignoring /dev/wd6a
raid0: RAID Level 1
raid0: Components: /dev/wd4a /dev/wd6a[**FAILED**]
raid0: Total Sectors: 156301312 (76319 MB)
raid0: Error re-writing parity!

# /sbin/raidctl -p raid0
/dev/raid0d: Parity status: DIRTY
# /sbin/raidctl -P raid0
/dev/raid0d: Parity status: DIRTY
/dev/raid0d: Initiating re-write of parity
raid0: Error re-writing parity!
/dev/raid0d: Parity Re-write complete

I had to run 'raidctl -R /dev/wd6a raid0' to beat it into submission.

this shouldn't have been necessary, should it?

grant.
