Have 4 drives installed, 99% free, but has been resyncing for more than 24 hours and is only 25% done. Is there a reason a resync shoudl take so long on empty drives, or does this indicate something is wrong with one of the disks?
The NAS had been locking up/ freezing and resyncing since installing latest firmware. No USB drives were connected, neither disk spin-down nor power timer were enabled. Read here some people where solving issue by performing factory reset and wiping drives after installing latest firmware. Did that, but has been resyncing ever since.

This is probably normal - how big are the drives?
Empty drives take the same amount of time to sync as full drives. RAID creates a virtual disk that the btrfs file system uses.
The sync requires either reading or writing every sector in the data volume (whether used by btrfs or not). This is needed to compute the partity blocks.
Re: ReadyNas 104 Constant Resync with wiped drives
Thank you for the info. They are all 4TB drives, so I will just let them go. They are almost up to 29% synced, which is much farther along then they ever got before factory reset, so it looks good. Thanks.
Re: ReadyNas 104 Constant Resync with wiped drives
A factory reset certainly would resolve a lot of problems, but for users that don't have a backup they should explore other options first. Furthermore depending on the cause of the problem if you factory reset but set things up exactly how they were before it's possible you may run into the same issue down the track. So it's certainly nice to get an understanding of what happened in order to try to avoid running into the same problem again.
