Re: kernel/4020: Panic when rebuilding RAID-1 RAIDframe array (reproducible)



I have the same with IDE disks [i386 obsd3.6-release]:

# raidctl -F /dev/wd1d raid0
Jan  9 21:17:12 samba /bsd: raid0: Failing disk r0 c1.
Jan  9 21:17:12 samba /bsd: raid0: Failing disk r0 c1.
Jan  9 21:17:12 samba /bsd: Unable to reconstruct disk at row 0 col 1 because no spares are available.
Jan  9 21:17:12 samba /bsd: Unable to reconstruct disk at row 0 col 1 because no spares are available.

# raidctl -s raid0
raid0 Components:
           /dev/wd0d: optimal
           /dev/wd1d: failed
No spares.
Parity status: clean
Reconstruction is 100% complete.
Parity Re-write is 100% complete.
Copyback is 100% complete.

# raidctl -R /dev/wd1d raid0

PANIC!
