I currently use OMV, but have lately been looking at alternatives such as freenas and such. Problem is, I don't really want to invest in a HUGE amount of RAM or CPU power at the moment to really take advantage of those options. Reason I was looking at switching is because of the 16 TB limit. I am still a bit confused by this. From my research I see it has to do with Squeeze and s2fsprogs 1.41.
I currently run OMV 4.35 and I see there are newer versions, but I don't think they will fix my issue as they are still running squeeze. I do see in the roadmap that version .6 should be moving away to Wheezy. Will this remove the 16 TB limitation? I currently have a 7x3 TB RAID Z2 array, but I want to grow it to about 10 or 12 discs, which would put me much over the 16 TB limit. I can hold off on this for a little while, but space will become an issue within a few months :(.
I do not know much about all the different types of filesystems out there, and currently I have enough harddrive space on other computers to relocate my NAS data and do a clean format of my nas and set up a different file system that will support larger than 16 TB volumes, or would this even matter? Is there another option that OMV has that will support higher size limits such as XFS, or will this have the same issue? This nas is for storing multimedia, mostly movies, tv shows, videos, pictures and such. I don't need lightning speed from it, I would just like to saturate a gigabit ethernet port, which I currently do with EXT4.
