As noted above, I'm getting an "interesting" discrepancy between the 4
devices I specified in my create and the results from mdadm. The
device seems to be working fine after transferring and playing several
files, but I find the "failed devices" bit particularly concerning.
Haven't found any way to get mdadm to tell me which device it thinks
has failed.
As for the command above, I get:
Personalities : [raid5]
read_ahead 1024 sectors
md0 : active raid5 hdd1[3] hdb1[2] sdd1[1] sdc1[0]
735334656 blocks level 5, 128k chunk, algorithm 2 [4/4] [UUUU]
unused devices: <none>
Which is what I would have expected. Any ideas?
