Before I start let me say that I am by no means an expert with this stuff, if you see something that you would have done differently let me know.
Ok, so I have a Ubuntu 18.04 server with a boot drive and 4 8T drives. My plan was to make 2 RAID 0 arrays, that would sync with rsync every night. I don't want to accidentally delete something forever so I decided to do the rsync route. I made my first array a couple of days ago, tested it, rebooted the server to make sure the settings stayed and then copied almost 3T of data to it.
I then went to make the second array, and that went great. However, whenever I reboot I have to rebuild the array by typing sudo mdadm --create --verbose /dev/md1 --level=0 --raid-devices=2 /dev/sda /dev/sde. Once I do that it mounts just like normal, but that deletes all the data on it. I tried sudo mdadm -A /dev/md1 and sudo mdadm --assemble --scan, neither one will bring the array up or say anything for that matter. mdstat also doesn't say that I have a drive /dev/md1
$ cat /proc/mdstat
Personalities : [raid0] [linear] [multipath] [raid1] [raid6] [raid5] [raid4] [raid10]
md0 : active raid0 sdb[0] sdd[1]
15627788288 blocks super 1.2 512k chunks
unused devices: <none>
Here is my mdadm.conf and fstab just in case
mdadm.conf
ARRAY /dev/md0 metadata=1.2 name=server-1:0 UUID=bc5145a0:d633e28a:940ddf09:7cfc2477
ARRAY /dev/md1 metadata=1.2 name=server-1:1 UUID=8a575273:38284856:a0a90411:41ef2a24
Fstab
/dev/md0 /mnt/Media ext4 defaults,nofail,discard 0 0
/dev/md1 /mnt/Backup ext4 defaults,nofail,discard 0 0
Any help will be greatly appreciated.
