ReadyNAS 104: Upgrade RAID5 Space - NO X-RAID
Dear all, I am using an RN104 with OS6.9.6 for quite some years now, with 3x3TB and 1x4TB installed. Now i am thinking of expanding the space and exchanging the 3x3TB with 3x4TB. I have a RAID5...
Hey Stephen,
thanks for the comprehensive reply!
Can i simply turn on X-RAID without losing data or having to reformat/resync my volumes?
Is there a formula on how to calculate the available volume space with X-RAID?
Would i be able to gain space in my current config just by turnin on X-RAID?
Not from the US btw 🙂

If you've not previously vertically expanded your volume, you just turn XRAID on and you'll lose no data. If you have expanded, then it will simply refuse, and you'll still lose no data. Turning on XRAID doesn't change the volume itself in any way, it simply enables the OS managing the RAIDs instead of you having to. If you have a situation that once XRAID is turned on, there is room for expansion, then that would happen immediately. But you don't.
The basic rule for XRAID size is "sum of the drives minus the largest". When expanding, there can be some exceptions and it's smaller. Netgear has taken down their XRAID size calculator.
