I use x-raid (OS 6.9). I have 3 disks (raid 5). Can I change raid 5 to raid 1?
For now:
disk 1: 3T
disk 2: 3T
disk 3: 8T
Raid 5. total space is 6T. the disk 3 has 5T not-in-use space.
I plan to buy a new 8T disk. and want it be:
disk 1: 8T
disk 2: 8T
Raid 1, total space is 8T.
Is that possible to do without copying all data out?
Thanks.

the slot 1 and 2 will be empty.
slot 3 will have the old 8T disk.
slot 4 will have the new 8T disk.
Is that OK?
Yes.

Yes, if you power down the NAS before you move them.

No, X-RAID is automatic.
FWIW, if you were very skilled with the linux command line, there would be another path to get you to RAID-1. But it is pretty complicated, and I think the process I outlined above would be better for you.
Netgear does recommend making a backup before manipulating disks, and I recommend having an up-to-date backup all the time - as RAID isn't enough to keep your data safe.

Not easily.
A much easier path is to
- hot insert a new 8 TB drive into the empty slot
- wait for XRAID to expand
The 2x8TB+2x3TB XRAID volume would be 14 TB - using all the space on the disks, and giving you a significantly larger data volume than the 8 TB you'd get with 2x8TB RAID-1.
But if you wanted, you could
- switch to flexraid
- create a jbod volume on a new 8 TB disk
- copy the shares to temporary shares on the jbod volume using NAS backup jobs (matching settings)
- remove any installed apps
- destroy the main data volume and remove the 3 TB disks
- format the older 8 TB disk in the NAS
- add it to the jbod disk for redundancy (RAID-1).
- rename the temporary shares on the jbod volume to match the original share names.
- reinstall any apps
Thanks for replying me.
