ReadyNAS Ultra 6 Plus.... 18TB -> 24TB
Hi, Currently using 6x3TB Seagate 3TB ST3000DM001 drives on a ReadyNAS Ultra 6 Plus. Not a very good drive though imo, had already 2 bad ones, curiously both were in slot No.2 of the NAS... wondered...
I am not very experienced in these NAS / RAID configurations at all, but I think I had chosen dual redundancy.
When I set it up first, out of 6x3tb = 18TB space, I had about 12TB space left for my files.
2 disks's space was kind of reserved for keeping the NAS running in case of failure.
That 12TB "usable" space is what I intended to upgrade, and therefore I got 6x4TB's for that reason.
One side note... a conflicting log message with above...
Doesn't this conflict with dual redundancy?
Maybe the X-Raid2 option I chose was single redundancy?? (then how come I had 12tb usable space out of 18TB's?)
I agree making backups is always a good idea (especially now!), I am in process of making backups even as I wrote these.
After all these backups are finished, yes I can and will do what is right.
Let me summarize basically what I need, maybe it's easier to find a conclusion
- I need more space than 12TB... whole reason of getting 6x4TB disks. After devoting 2 disks to safety I expect to have 16TB usable space (at least).
- Since I'm using "desktop" level drives, I will need the NAS to be up and running even 2 drives fail at the same time. I can live with 1 drive failing too but I think it's too much of a risk.
- Which RAID level should be optimum based on above with 6x4TB disks?
these are my basic needs.
Optionally it would be nice to have answers to these below as well:
- In the future, ability to upgrade to 6x6TB maybe?
- In a nutshell pros/cons of OS6
- How to do off-line expansion process? Never heard that one before. Or shall I simply restore to factory defaults? (after all I only have 3 dirs to assign and 1 add-on anyway...no biggie, can redo all settings in matter of minutes)
- "If you decide to go with the factory default, you might as well go with flexraid RAID6 - not much point to xraid2 if you are at the 16 TB ceiling. "
This 16TB ceiling is for x-RAID2? Basically which Raid configuration you think would best serve above criteria.
Guys, again, tyvm for all replies really.

A disk was removed from the ReadyNAS. One or more RAID volumes are currently unprotected, and an additional disk failure or removal may result in data loss. Please add a replacement disk as soon as possible.
