I have a raid array that for some reason, has stopped being assembled. It was called /dev/md0, but now /dev/md0 no longer exists and /proc/mdstat only contains another array I have, not both of them.
However, if I run
sudo mdadm --examine --scan, both appear
ARRAY /dev/md/1 metadata=1.2 UUID=aee0e79d:1d897c57:b87e879b:7fb3e1d9 name=desktop:1
ARRAY /dev/md/0 metadata=1.2 UUID=e5c5b859:bdcb97ea:f561d1dc:fabdacef name=desktop:0
The missing array is /dev/md0, so it apparently exists to a degree but it is not being assembled. How can I reassemble this array without losing the data on the disks in the array?
