I’m worried that I know the answer to this but here goes…
I have a Drobo V1 with 4 x 1.5TB drives atached.
When I initially setup the drobo it was connected to my iMac directly with USB. During the build I was not allowed to create on big Volume and had to create 2TB max volumes as that was a USB limit (apparently). This I did and I started off with 2 2TB volumes and have ended up with 3 since I upgraded to the 1.5Tb drives.
One volume is used for TV stuff, one for movies and the other for odds and sods. I’ve been getting a lot of finder 51 errors lately which may or may not be related but it has highlighted that the volume with the TV shows on has only 30Gb free from the 2.2Tb volume.
Now I know that the drobo manages the storage itself and that the volume info should be ignored but I would guess that this is not the case once you get to the top end of that space as the OS will see that the filesystem is full and act accordingly.
So I guess my question is
What happens to a filesystem that hits the 2Tb volume size limit ?
Is there any way to expand it ?
I think this will be a nightmare no matter what the answer is but if I can ask that you giggle in quiet at least
