Thinking about it (dangerous thing to do) the questions arose of (1) how does mdraid actually work, is there a primary drive that is uses for read/write while the other is there for sync/backup?
Not that I know of - I think it would make sense to (attempt to) read from both drives.
(2) If you can't write simultaneously to both at the same time using the same clock cycle (can you??)
Not simultaneously, the write command is undoubtedly sent to all mirrors one by one.
so somewhere it seems there must be a write/copy function in the mdraid scheme, and if the drives are slaved together by my the data in mdadm.conf,
AFAIK, use of mdadm.conf is optional. If your RAID partitions are type 0xFD, the driver can sort out the rest. /Per -- Per Jessen, Zürich (7.1°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
