Date: Thu, 3 Apr 2003 11:49:42 -0800 (PST) [thread overview]
Message-ID: <200304031949.LAA28555@astra.scripps.edu> (raw)
Shouldn't /proc/mdstat have [UUUUU] instead of [_UUUU]? Perhaps
this is running in degraded mode. Also, you have 'algorithm 0',
whereas my raid5 has 'algorithm 2', which is the left-symmetric
parity algorithm.
