I have an EX-4 configured with 4 disks 4TB disks and two RAID 1 volumes. After a recent power failure, the NAS has been rebuilding volume one for 5 days now (volume two is not mounted). Volume one was almost full with only 88 GB remaining. When I check on the status, the build time is stuck on 27:39:36. How long should I expect to wait to rebuild this volume? Is there some thing I can check to determine if any real progress is being made. I think I can access my data on the volume while it is rebuilding, but I need to determine if this unit is really protecting my data which is why I invested so much money for it the first place. Unfortunately, the unit was not plugged into a UPS when power was lost, but I’d rather know now if this NAS is just a clunker since my data is important to me. From all the issues and comments on this forum, it is looking like WD EX-4is not a good choice if your data and time is important.
RAID status rebuild is at 16%. When I refresh the page, there is a number at the end of the status that does change (UI does not display the entire number/message). At this rate, it will take a month to complete.
