Scrubbing an empty array returns exit code 1

[gilgwath]

Hello

First off, thank you for this wonderful tool!

Today I initialized my first snapraid array and I use snapraid-btrfs-runner to automate some of the maintenance. I ran the tool on my as yet empty array and it kept reporting that snapraid-btrfs scrub failed. I ran the command manually and got the following message:

Using 0 MiB of memory for the file-system.
Initializing...
The array appears to be empty.

To me this is not an error condition, just what should happen if the array is empty. So, I checked the exit code echo $?and it returned 1. That's why snapraid-btrfs-runner assumes there has been an error. Of course, this should go away once the used filled the array with some data, but since there is logic to check for this condition, shouldn't return exit code 0in this situation?

Best regards
