ReadyNAS NV+ Freezing/Locking up. Diagnostic Help Please!
Hey Guys,
My reliable ReadyNAS has been given me issues this last week. It's a ReadyNAS NV+ v1 loaded with 4x2TB WD Green drives. FW is current at 4.1.14.
I'm posting here becasue I found this thread:
Which is the identical symptoms I am getting from my unit.
The unit boots, starts a FS and Quota check since I had to hard unplug it due to the power button being non-responsive since this started happening. After the 2 hours that check takes to complete, I can access shares/web console etc for about 30 min. Then the activity lights stop, the power button becomes unresponsive, and share access stops.
In the thread linked above, it looks like there was 'Current_Pending_Sector' value which indicated a failing/bad disk. I'm hoping having someone's input on the logs will point at the same issue with mine and not some logic board issues or hardware problem. Keeping the data intact and accessible is my priority at this point.
I have been able to extract the logs and loaded them here: https://drive.google.com/file/d/0B7tgX-P1b8UgbTA3blk2VWZ1TkE/view?usp=sharing
Any input would be greatly appreacited.
Thanks

That set of logs is incomplete.
That file is not shared.
So you don't have a backup?
- Unfortunately no. What are your thoughts from the log?
Not sure why it is freezing but there are some tests you can run.
Power down the NAS, remove the disks (label order), connect them up to your PC and test them e.g. test SeaGate disks using SeaTools or WD Disks using WD Data Lifeguard Diagnostics.
Perhaps also run the memory test boot menu option at least twice.Thanks for the steps. I'm going to scan the disks one by one with WD Diagnostics, and as you suggest, self test the memory in the ReadyNas.
Will likly be 2 days before I can get through extended scans on all the drives. I will check back here once completed.
- Thanks again mdgm.i was able to scan each drive individually and identify errors on one disk. I have removed that disk and verified that the nas boots up and files are accessible, obviously this isn't a fix as it is still in a degraded state. The memory tests checked out ok. Two follow up questions:
1. How could one failing disk like this crippled the nas completely and why wouldn't the nas detect any issues with the drive or give any indication of a problem with a specific disk.
2. Moving forward- should I attempted to repair/ format the problematic drive or am I able to replace that drive with a drive of a different size and have the readynas rebuild the array? Can x-raid rebuild in that situation?
Thanks again1) depends on the failure mode. RAID doesn't guarantee that the system will boot with defective drives.
2) I'd replace the disk with another 2 TB drive (I recommend a WD20EFRX). You can't go smaller (the array won't build) and you can't go larger (since 2 TB is the max for your NAS).
