ReadyNas NV+ Checking FS stops at 48%
I hope someone can help me, warning I'm not technical !!
ReadyNas NV+ v1 - 4 x 2tb drives
After running flawlessly for 5 years it decided to do a Check FS when I turned it on, don't think there was a powercut last time I used it.
Says" Booting.... Check FS: 0% and all 4 green lights are on and the Act light flashes away. Get to 48% then act light just flashes every now and then but doesn't go past 48% and the RAIDar software loses connection to it. Tried a few times and it always only gets to 48% then stops. I have tried leaving it for 24 hours but still on 48%
If I "skip CS check" it boots up fine, I seem to be ablwe to access all the data and can log into the NAS. Looking at the volume settings it says "Resync 6% complete time to finish 1 hr 2 min" but after a few minutes it locks up and can't access data or log into the NAS, web page just has "ReadyNAS Null".
I saw on another post that large log files can cause a problem so deleted those (under status menu) when I has access but that hasn't helped things.
I do have a full backup so losing the data is not a problem just an inconvenience I’m pleased to say.
Any idea what is wrong and how to fix it ? thanks
Disk 3 seems to be failing. You could try shutting down the NAS and booting the NAS w/o it.

It sounds like a failing disk or a volume that has somehow gotten corrupted.
Are you able to see the SMART stats for the drives while it is running (status->health in the web admin page)
Thanks for your help.
By Skiping Vol Check can access SMART stats. Didn't have long before lose connection but took a screen grab of each disk.
Don't know what I'm looking for but the big difference comparing the four disks is the Raw Read Error Rate figure which is 0 for Disks 1,2,4 but 60766 for Disk 3. The other difference is Current Pending Sector, Offline Uncorrectable, Multizone Error Rate figures are 0 for Disks 1,2,4 but 5,2,22 respectively for Disk 3.
The Health screen listing the disks shows status OK for all disks.
When I booted it not checking volumes it first says Booting... Disc 4 Sync. Also if I look at Volume setting Status was Resync 6% complete time to finish 49.1 min.
Yes I have a backup of the data I'm pleased to say !!
Again thanks for your help.
Just worked out how to upload images :-
Just for completeness if anybody else finds this thread and has a similar problem.
Brought new disk, fittted whilst NAS running, received these messages:-
11:58 - Hotplug disk event detected (NAS1) - Disk add event occurred on SATA channel 3.
11:58 - RAID event detected (NAS1) - Disk initialization successfully finished.
11:58 - RAID event detected (NAS1) - RAID sync started on volume C.
00:52 - RAID event detected (NAS1) - RAID sync finished on volume C. The volume is now fully redundant.
As you can see it took about 13 hours to sync the new disk.
All looks well now, I'll keep an eye on the other disks as getting on a bit now.
