NV+ - No fileshares - no frontview
I have a NV+ with 4 2TB disk. I haven't used it for 6 months and I suddenly became aware of that none of my network shares were available. After some investigation I found that this was not the only...
I think the next step is to power down, and test the disks in a windows PC. Use vendor tools (lifeguard for western digital, seatools for seagate), and label the disks by slot so you can return them to the proper position later on.
You can get in via telnet (in tech support mode), but you won't be able to get in with SSH unless it was enabled before.
Thank you for your fast reply.
When you say "test" the disk, excatly what results would you expect to explain what I'm experiencing? I'll try it, but as all 4 disks are reported "ok" by RAIDar I dindn't think this could be a problem.
(I have 3 samsungs and 1 WD, all 2TB configured in xraid.)
I'll do that and return, unsure if I'll be able to do it this week.
One more thing I noticed now when looking at the disks in RADIar. RAIDar displays a blue dot at the beginning of the line for my NAS (it's blinking in the help-file, but solid in my RAIDar). From the RAIDar help file this is:
RAIDar Help
*blue dot* Background task active A lengthy background task such as a system update is in progress.

It is very possible for disks to fail without the NAS "noticing", so it is good to rule out disk issues early.
Another possible cause for your issue is a filling OS partition. Paid netgear support (my.netgear.com) could fix that (ask about per-incident support). Or if you are comfortable with linux commands, you could try to mount the OS partition in tech support mode, and see if it is full.
Sorry about the late answer.
My desktop has been out of bussiness, so I had to "awaken" it this weekend before i could proceed with the disk-testing.I first tried your 2nd suggestion (the log files) since this didn't require any preparations.
I'm not exactly what I would describe as "comfortable" with linux commands, but I know the basics and google is my friend so based on other similar threads I gave it a go.To trace back what I did
1. Started techsupport, holding the power button for 15 sec when turning on
2. Logging in using root/fr8ntview (i think)
3. Found an instruction, telling me that
# /bin/start_raid.sh
# mount /dev/hdc1 /sysrootwould be the way to go
4. Did these:
# /sysroot/bin/df -h
# /sysroot/bin/df -i
# /sysroot/usr/bin/du -csh /sysroot/var/*
# /sysroot/usr/bin/du -csh /sysroot/var/log/*
5. Found that sysroot/var/log/upnp-av.log is 1.2 ?B and full of:
[2017/08/11 17:39:22] minidlna.c:1294: error: accept(http): Too many open files
It had been filling up since 2013 until 2017 (11 aug, which might very well be when the NAS failed)
(**Right now I'm kicking myself, cause I'm actually not sure wether the file was 1,2GB or 1,2TB. In my head at the time it was 1.2TB which could explain the disk beeing full, but in my notes I've written 1,2GB which is "nothing". I did though recall that it reported the disk as 99% full before I emptied this file, but I'm not entierly sure. I do however don't think that this affects the current state, as I now know that "right now" the drive isn't full****)
6. Did a
#echo > upnp-av.log
to empty the file
7. Rebooted the server, did an OS-reinstall, but no luck.
This weekend tested my disks. Two of the samsungs and the WD completed the test in 5,5 hours (each) with no errors. The last samsung (which is the disk in slot 1) failed, giving a log of LBA errors (failed sectors). I think the whole test took about 10 hours (although it's identical to the other samsung disks).
So - I'm just speculating - Is the OS located on the disk in slot 1?
Could the situation I'm seeing with the LEDs be that the NAS is neither capable to load or update the OS due to disk-failure?
If I did a low level format of this disk and reinserted it in slot one, should the NAS reinstall the OS and rebuild the disk from the XRAID?I the above is the way to go, I could of course buy a new 2TB disk to be safe, but as the NAS is old and I'm considering a new one, this would be wasting money on a disk it's unlikely to ever use for anything else. Even worse, it's a complete waste of money if this doesn't fix my problem (that's why I would try formatting the disk before buying a new one)
Sorry about the long post, just trying to provide as much information as possible, any input is appreciated.
