How do you make all the disks active mirrors? When I add a third
partition
to an functioning RAID1 array (mdadm -a), it always enters as a
'spare'. Only
after another disk fails out will it be brought into sync with the
remaining
active partition.
(I'd like the third partition to be brought into sync, and kept in sync,
with the other two immediately, so that a fail does not trigger any
flurry of activity.)
when you create the array:
mdadm -Cv /dev/md0 -l1 -n10 /dev/sd{a,b,c,d,e,f,g,h,i,j}1
Thanks for the tip.
I'm hoping to do this to a prexisting array, so I'll probably need
to use --grow rather than -C together with -n/--raid-devices, but
you've pointed me in the right direction and I'll try this soon.
Merci!
