RN204 resync after successful resync, any idea what's going on?

Yes, i'd noticed that in one of your other posts to someone else. After my near total data loss scare, the unit is currently backing up to a cloud provider (the only other task running) I think the X-RAID notion is neat but i've since ordered 3 more WD Red drives to swap out my 3 old drives, that'll bring all 4 drives up to new WD Reds. I don't see myself doing another storage space upgrade in any time in the future, it'll be faster to flatten the config and start again as I already have a local backup anyway. I realise that the reshape time shouldn't really matter but I kinda like completed processes and to swap out 3 more drives at the present rate would look like around 3 weeks. On the basis that firmware 6.5.0 is just around the corner and that i'd rather wait for my cloud backup to complete (that'll be a few days), i'll just schedule a flatten NAS day and clear it all, fresh firmware and start again. So basically, my original idea to buy a diskless unit and just throw some old spare drives at it as a cheap storage thing has totally turned on its head and become a chunky investment!
