Hi Alvin,

I've never heard of "hotswapadd", did you mean "raidhotadd" ?

I also have raid-1 problems. raid-0 gets started fine, but raid-1
starts in degraded mode, using only hde.  (started after I had to
rebuild the partition table on hdg)
I can manually raidhotadd /dev/md? /dev/hdg?
which restores the arrays fine, but it doesn't 'stick'.  I have to
raidhotadd after every boot.

Any ideas?

Thanks,
Patrick.
