I don't need to do anything on the command line to get it to show up?

Once you swap drives, post the output of cat /proc/mdstat. You might be able to just use the recover button in the web interface.

It didn't add it automatically. So, what is the output of fdisk -l

Now I would try:

mdadm --stop /dev/md127
mdadm --assemble /dev/md127 /dev/sd[acdefghij] --force --verbose

jkingaround · 17. April 2016

Code

root@NAS:~# mdadm --stop /dev/md127


mdadm: stopped /dev/md127


root@NAS:~# mdadm --assemble /dev/md127 /dev/sd[acdefghij] --force --verbose


mdadm: looking for devices for /dev/md127


mdadm: no RAID superblock on /dev/sde


mdadm: /dev/sde has no superblock - assembly aborted

sde is the one i replaced.

ryecoaaron · 17. April 2016

Try:

mdadm --assemble /dev/md127 /dev/sd[acdfghij] --force --verbose

If that doesn't work, try:
mdadm --assemble --scan

If that doesn't work, I have other things that may work but more dangerous.

jkingaround · 17. April 2016

that worked! so now i wipe and add the drive i swapped yes?

ryecoaaron · 18. April 2016

Just for my knowledge, which one worked?

Post cat /proc/mdstat just so I can be sure what to have you do.

jkingaround · 18. April 2016

mdadm --assemble /dev/md127 /dev/sd[acdfghij] --force --verbose is the one that worked.

Code

root@NAS:~# cat /proc/mdstat

It is still read only. Try:

mdadm --readwrite /dev/md127

If that works, click Recover in the web interface to add the newdrive to the array.

jkingaround · 18. April 2016

That worked, didn't give me any errors. In the process of recovering the raid now. thanks. here's to hoping it works
