HP Gen10+ - mdadm error reported by logwatch

[Robert Moskowitz]

This is probably something left over from my install, and I would like 
to clear it out.  That said, logwatch reports:


  --------------------- Mdadm Begin ------------------------

  mdadm: cannot open /dev/md/ubuntu-server:2: No such file or directory

  ---------------------- Mdadm End -------------------------

  Google suggests:

# mdadm --assemble --scan
mdadm: Value "ubuntu-server:2" cannot be set as devname. Reason: Not 
POSIX compatible. Value ignored.

OK...  So

# cat /proc/mdstat
Personalities : [raid1] [raid0] [raid6] [raid5] [raid4] [raid10]
md0 : active raid1 sdb[0] sdd[1]
       3906886464 blocks super 1.2 [2/2] [UU]
       bitmap: 0/30 pages [0KB], 65536KB chunk

md2 : active raid1 sda[0] sdc[1]
       3906886464 blocks super 1.2 [2/2] [UU]
       bitmap: 0/30 pages [0KB], 65536KB chunk

unused devices: <none>

So how can I clear out whatever I need to clear out?

thanks
