RN31600 and RAID1 with 5 disks
Hello all. I just bought a RN31600 and need to use it with 5 disks in RAID1 mode. However, as long as i put more than 2 disks in, the option only allows to create raid5 or raid6 with my 5 drives. I...
Creating a RAID1 on 5 HDDs is possible from SSH though.
Don't know if I should advise that, it depends on your experience in Linux systems.
I tried it on my unit and it worked:

** edited due to my error, forgot to reboot the nas **
everything works as planned. I assume hotplug and autorebuild are still enabled after doing this ?
Cheers again !
Sure, but if you run into issues support can't be expected to help with a volume that couldn't be created using any of our UI options.
Your latest post indicates just why what you've done is something that support would deny help for.
You may need to enter an entry for the data volume to /etc/fstab doing e.g.
echo 'LABEL='`hostid`':data /data btrfs defaults 0 0' >> /etc/fstab
You may then need to do e.g.
# systemctl restart readynasd
and hope that the necessary entries in the database are created.
Thanks but actually everything regarding creating shares works perfectly from the GUI now i've rebooted the unit.
