Hi all,

 

I am currently using unassigned disks and mount each disk as a share. However, only a single disk do not have enough space for me as a share. Therefore, I would like to create a pool of disks such that I can create a share that can span across multiple disks (like what the array does).

 

Is it possible to have different size of disks to achieve the above? If yes can I add any new disk to this pool in the future?

 

Or it can only be achieved with same size of disks, and use ZFS RAID0? I like the fact the a single file will not span across multiple disks in the array, but I am not sure if this is also achieveble in the pool as I can use only RAID0 is the option for me to have all usable space (if all disks with same size)

 

Thank you!

A zfs stripe will use all the capacity from different sized disks:

Thanks for the reply. By doing so, can I add/replace/remove disk in the future? looks like from here it says cannot for RAID0, but not sure if this ZFS stripe count as the same. thanks

Btrfs with the ‘single’ profile will support using all available space and adding disks in the future.

 

note that both the btrfs and ZFS solutions mean you lose ALL the data on the pool if ANY of the drives in the pool fail.

Thanks for the reply. I am aware of such possibility. That being said, is there no soulution like the array but without parity, which means a file will only stays on a single disk?

Nope, but multiple arrays will be supported in the future.
