(Re)creating a volume

[oRBIT]

In my DS918+ I've got 2x6TB (=volume 1, almost full), 1x1TB SSD (volume 2) and 1x3TB (=volume 3). What I'd like to do is append my 3TB disk to volume 1 (So I get 9TB of space instead of 6TB). Of course, this is not possible, unless I recreate the entire thing and starts building the SHR with the 3TB disk.
Anyone knows any good ways to do this with minimum effort? I guess in theory I could backup entire volume 1 and recreate it, but.. Well, perhaps that' s the only way of doing it, but still.. Ideas wanted..

You pretty much nailed it. Not many options if the 2x6TB is almost full.

Rather than go through those drive gymnastics, replace the 3TB with a new 6TB drive. Yea, it costs a bit more, but it doubles your volume1 capacity and offers better "future-proofing" before you end up swapping the 3TB drive for a 6TB down the road.

I think @Telos covered it there. It's the old saying 'time is money' and what's your time worth? Either backup everything and recreate the RAID or buy a new 6TB and switch out the 3TB. Even the new disk approach needs you to backup the 3TB, then a long-ish wait while parity checks complete to add the new disk*, and finally restore the 3TB's data.

So even the easy way will take quite a long time, but you probably will get an even longer rebuild starting from scratch.

*I added a third 8TB disk to my 2x8TB SHR and it took 41 hours to complete, even with Storage Pool -> Configurations set to faster resync.
