Free space after expansion
I have an RN428. 5 8TB drives, 3 14TB drives. I put in a 4th 14TB drive and expected that the RAID6 would expand after it.
But it has 48 hours left to sync with the log below and at 10:59PM I see the expanded free space. Am I OK to start moving data to it or should I wait?

Those entries are a little concerning, looks like disk 4 is acting up.
We should check that out first.
I can take a look at the full logs if you like.
On the web admin page, go to "System" > "Logs" > click "Download logs".
This should download a zip file containing all the logs. You can then upload that zip file to Google Drive, Dropbox or similar and make a link which I can use to download it. PM me this link - don't post it publicly here.
Cheers

I'm not sure what you are seeing - it looks normal to me (since there are two RAID groups). But it is prudent to check before loading more data.
joe_schmo : on the original question... While you can add data while the volume is resyncing, the total time will be slower. Usually it is fastest overall to wait until the resync completes.

It would certainly be useful if the log would show which RAID group is re-syncing. Others have also asked questions regarding the second (or more) sync for a multi-group volume because the log does not explain why there is more than one sync.
Alternately, don't report completion of any sync until all groups are complete.
