problem. I was just curious as to how long an actual raid5->raid6 reshape would normally be or this setup. I expect it normally can take a while as it has to rewrite a lot of data (11TiB worth).
In my experience it takes 5-15 times longer than a normal resync takes, to reshape from raid5->raid6. So for your 3TB disk size case, I'd say expect 4-8 days or so.
