Is there a method for balancing by total space used in bytes (not percentage)?

I'm using SNAPRaid and it would be nice if I could automate balancing by used space by bytes to keep the parity file size optimized.

I can't find any options to balance by used space, only by percentage used.

Not that I know of. It's kinda problematic as balancing by absolute (rather than percentage/relative) used space risks running into the problem of moving files into disks with insufficient free space.

As a workaround - I'm not familiar with SNAPRaid to know if this suits - could you perhaps resize the volumes on the drives so they're all the same size, or put non-pooled file(s) on the pooled drive(s) of a suitable size so that they all have the same "free" space?

If you really need it though, I'd suggest making a feature request to add the option (perhaps to the Disk Space Equalization balancer?) via the contact form.

Balancing by used space seems such a basic requirement. It is good practice to balance your data evenly across all drives in case of a failure. Balancing by percentage used would result in much more data loss on larger drives when you have space available on smaller drives.

As an update, I have been informed that the latest beta now includes this feature.
