ReadyNAS 2100 won't boot, disk lights on, power light off
So my lights are the same as in this previous thread: https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/ReadyNAS-2100-won-t-boot-disk-lights-on-power-light-off/m-p/919786#M63715 U...
So the seller mentioned that they may have gotten the disks out of order when putting them back in and recommended a factory reset, which I just initiated. Hopefully this will solve the issue. :)
So it must have worked! The unit is rebuilding one of the drives for some reason, but the empty shares are visible and working and can even transfer 30MB/s during the rebuild. :) I'm happy.
It's also nice that the interface is a twin of the Ultra6 so setting them up to be the same will be a cinch and I expect an rsync between them will be nice and fast as well. :D
It should be re-building the entire volume. Anyway, yes, a factory default was going to be my suggestion if nothing on the drives mattered to you. The drive order likely wasn't the issue. More likely, the OS partition on the drives was damaged in some way.
From what I could tell in the previous thread, it looks like a log file can get too large and cause problems, but the factory reset did clear it up as it is back to 100% again. I do need to probably scrub test the entire volume before I put anything on it. I've also thought about putting in 4x 16TB exos drives I have just to 'see what this thing can do'. I'm sure the volume won't be able to exceed 16TB, but will it allow me to make multiple volumes?
I was almost certain that drive order matters on these if it is more than a single drive. Is this definitively not the case?

Yes.
FWIW, if you were to do a factory default with 4x16TB in place, that might well work. Though expansion after that really wouldn't be possible.
The 16 TiB restriction is because the NAS normally uses 32 bit inode addresses. But if it knows that 64 bit addresses will be needed when the volume is created (because it will be larger than 16 TiB), then it is supposed to use them.
There is also the 8 TiB growth limit though, so you'd need to make sure you have all 4 disks in place.
Though this is not something I've tried. If you do try it, I'd suggest making sure you are using 4.2.31.

It's not supposed to matter, but in practice it does matter sometimes. If you have more than one RAID group it seems to matter more. So I generally do recommend preserving the slot order.
