May 4, 20242 yr Solution Effectively unlimited compared to the size of drives you can buy. While there may be some limitations somewhere over what the theory is on file system maximums (eg: XFS supports a maximum 8 exobyte drive size), not currently available hard drive even remotely comes close to this size.
May 4, 20242 yr Author Thank you for that. And of course the price drives plays into it as well. I just needed comfort that stepping up to 16 TB or higher it ok. It wasn't when I built my server years ago! Thanks
May 4, 20242 yr Community Expert At one point Unraid’s main file system was reiserfs, and that has a built-in upper limit of 16TB on a drive. As long as you avoid using that on larger drives there should be no problem due to the drive size. That limitation is one reason reiserfs is now deprecated and support scheduled to be removed from Unraid when the Linux kernel developers drop support.
May 4, 20242 yr Author Right. So what is the current supported/recommended filesystem? Might as well double check to make sure I don't run into trouble. If I read min correctly, it is xfs
May 4, 20242 yr Community Expert Unraid currently supports xfs, btrfs, and ZFS with xfs being the default for array drives and btrfs for pools, but you can go with the mix you like. Reiserfs is also still supported for legacy reasons but is deprecated and Limetech have warned it is slated for removal at some point in the relatively bear future.
