Spares Missing event in case of spare group?
Hi!
I have two RAID1 sets of equal size, with one spare shared between them. When I reboot the system I get a Spares Missing notification on one of the arrays.
Since this is a false positive, is there a way to avoid it?
Extract from mdadm.conf:
ARRAY /dev/md0 level=raid1 num-devices=2 spares=1 UUID=19e69537:f7a6aec8:5a5f7576:3fc29e0d spare-group=swapgroup ARRAY /dev/md1 level=raid1 num-devices=2 spares=1 UUID=5e728621:c8b356a8:01f8e270:f0e280cb spare-group=swapgroup
Thanks, Jan

Yes. Remove the "spares=1" from each line.
The sole effect of this text is to tell --monitor to expect a spare, and to complain if no spare is found.

Many thanks. I hadn't picked that up from the manpage, so here is a patch for your consideration:
