Resync progress over 100%

[walkera22e]

Hi everyone

New dude here..

I've a strange problem that I've never seen before and I don't know what to make of it. I reinstalled my RN4220X and created a RAID10 array using 6x3TB disks and everything looked ok as the volume resyncing was below 100%. But now the resync is still in progress and now it's way over 100% and I don't know why it does this. I've tried to reboot the NAS but it just keeps on resyncing no matter what I do. It works just fine with iSCSI and my VMware hosts but I kind of would like it to finish the resync 🙂 Any thoughs?

I'm runnig version 6.7.4 on it

Another customer has just ran into this as well: https://community.spiceworks.com/topic/2006592-netgear-raid-rebuild-over-100?page=1#entry-6985783

I've seen some similar cases reported in the past - I suspect it is a reporting issue, and the resync is still running.  So I suggest letting it run (hopefully to completion).

Thanks..

I looked at /proc/mdstat and sure enough, it says 86% and 200-ish minutes left. I guess I'll just have to wait then 🙂

Aaaand it's done..

It went up to 300% and I bet there is some "logic" to that number.

Thanks for your replies.

Likely its related to the expansion history (e.g., I am thinking that the volume is comprised of three RAID partitions).
