ReadyNAS 104 Replacing the disk with a larger one
Hello, I have a ReadyNAS 104 with four drives (2TB, 2TB, 12TB, 6TB) set up as spare JBOD. I am running out of space on the drives. How do I change the disk to a larger one? Regards Robert

Spare JBOD????
Assuming you meant 4 JBOD volumes, then you need to
- back up the disk you want to replace
- delete the volume on it
- hot-insert the replacement drive
- create a new volume
- configure the shares, any backup jobs, etc again
- restore the files from the backup.
If the disk holds the primary volume, then be careful to back up the home folders if you use them. Perhaps also uninstall any apps, and reinstall them when done.

Yes, a backup JBOD, because I have a lot of irrelevant data.
I understand that make a copy by plugging in the drive through, for example, a USB controller and running a copy job?
This is terribly slow but can be done.
Thank you for your reply.

"a backup JBOD"???
- Can you give us more details on how many volumes you have, and what RAID modes they use?
- Also, are you upgrading a disk that holds a JBOD volume?

That is one way. Another is to connect a USB drive to a PC, and copy over the network.
In general, that's one of the downsides of using JBOD or RAID-0.

my system looks like this:
and for a start I would like to replace Disk 2 and Video
I am wondering if JBOD is the best option for you. Expansion is painful, and you have two rather small volumes. The bulk of your storage is media, and the two 2TB volumes are underutilized. The Video volume is too full (generally you want at least 10% free space on BTRFS volumes). The Plex volume is still ok, but on the edge of too full.
If you want to switch to XRAID, I'd suggest getting two 12 TB drives. Then you'd have an 3x12TB + 6 TB volume (~27 TiB capacity), which is 8 TB more than you have now. You'd need to back everything to switch.
Either way, RAID redundancy is a convenience, and isn't enough to keep your data safe. So anything you need to preserve needs to be backed up somewhere else.
