Permissions change to read only\ missing share

Hello,

It sounds like you may have a drive compatibility issue. Is your drive listed here.

If not, I would imagine that is your issue, and should be replaced with a compatible drive. If not there may be an issue with the chassis and you should probably contact support.

It sounds like I am having a very similar problem.
I have had an NV+ [4.1.6] for several years without problem. Home use machine, Media server.
Recently I started to accumulate SMART errors on a Seagate 1TB drive.
I ultimately RMA'd the drive. The replacement: BARRACUDA ES 7200 SATA 1000 GB should be completely compatible.
I swapped out the bad drive and the NV+ sync'd itself and everything was fine. I was able to access files (not sure abt writes at that point).
A few days later I lost connection to the NAS. Raidar could not find it, it was running but unresponsive to pings or from the power button. Ultimately I had to pull the plug. Again, it came up, np, resync'd and sent me an email that the device was shut down incorrectly... The unit came back and every thing seemed fine, I could see all my mounts from PC's (XP 2002 sp3).

I started getting emails, from the NAS that the backups were failing, could not write, file protection errors...
Job: 003
Protocol: cifs
Source: //192.168.0.115/solderfolder
Destination: [dad-pc]/backup
cp: preserving times for `/dad-pc/backup/Anniversary': Read-only file system

I looked at my mounted dirs from the NAS and found that I can read from them but not write to them. I can't create a folder... Permission denied.

I can access the mounted USB volume and that is writeable.
The owner of the non writeable folders are listed as: NAS-SOLDER\admin. I have a user account that I usually connect with "Dad" . I see some folders with the owner NAS-SOLDER\Dad, but most are admin. I never connect to the NAS from the PC as admin. That is only my frontview login.

I have not changed any of the share settings.
My primary share "Media" has Default access disabled and Dad as a "Write enabled" user.
The advanced options: admin/nogroup rw rw. None of these settings have changed in over a year.

Before I start changing things I wanted to see if this is a known problem and if there was a thread that addressed this issue. I have not found one yet.

I have a Public share that is default access r/w with r/w for everything. Again, I cannot create a folder here or drag a file into a folder either.

Lastly, when i started seeing the problem, I tried to disconnect mounted dirs and I started getting errors "There are open files, are you sure you want to disconnect..." I have never seen those messages before.

I'm stumped and could use some direction.

TIA

ok, i managed to sort this out. I was going crazy trying to figure this problem out and i decided to ssh into the box and poke around. That required me to add the add-on EnablerootSSH. Part of the add-on install process had me re-boot the NAS. After I went through the reboot process the box came back up and "boom" permission issues resolved, by themselves (?). Box is resyncing now from the shutdown, another 5 hours needed. But it looks much better now.

One thing I do see, via ssh, is that practically everything is owned by "admin nogroup". This should not be the case. I created most of this content from my XP. When I drag a file into a folder it goes in as "Dad dad-grp" which is what I would expect to see. So something went rogue and reset all the ownership on everything. Not good.

This suggests that you have reset share permissions at some point via the Advanced Options for the share, which will reset the ownership of all files/folders to the same as the share ownership specified in the Advanced Options

ok, another development.
The resync completed last night. Now that the resync is complete, i have lost the ability to write to my folders again.

I can see the file i added last night It's owned by NAS-SOLDER\Dad, which tells me that file ownerships were not changed by the re-sync, at least for this file. I see a specific folder owned by NAS-SOLDER\Dad.
If I'm connected as "Dad" I still cannot add a file to that folder that is owned by Dad.

I just tried disconnecting the shared drive and re-connecting it. It disconnected and I remounted it. When i tried dragging a file into the same folder i was able to last night, the NAS hung.

The front panel is dead, Raidar can't see it. Now I have to pull the plug and re-boot the device again, which entails another 6 hour resync. Ugh.

I HAVE NOT changed the advanced permissions on any shares in over a year. The device has gone up and down within that time frame and I have not seen this problem before.

Interestingly, I have a backup job that runs at midnight. It backs up my PC to a Share on the NAS. When the NAS permissions go bad, the job fails, cannot write to the share...
Last night when I was working on this problem, before the re-sync was complete, the backup job fired off and was successful. Which leads me to believe that by the time the rsync completed the file ownership/permissions are getting changed and is breaking things.

This is pretty frustrating.

ok, same thing, NAS is resyncing, while it's doing that I can write files to a specific dir owned by NAS-Solder\admin, as Dad and they appear as owner NAS-Solder\Dad. This is what IO would expect to see.

The files I have been testing with, from my PC, are being dropped into the "Martial Arts" folder. The dates are being preserved for some reason and should be Sept 10 not Aug 24. That was the original file creation time. Apparently that is being saved.

Either way. I dropped the movies.txt2 earlier this week and last night i added the movie.txt3 file.
Both are going in as owner: Dad and group dad-grp. Which is correct.

The errant behavior is that when the rsync completes, i cannot write top that folder.

Does anyone see anything odd?

it looks to me like all the dirs are 777, so write permission should not be an issue.

Another oddity:
I was able to create a test folder from my XP mount before something changed after the rsync.
Now if I try try to delete the file from XP; movie.txt4, it asks if i want to delete the file, i say yes, it deletes it but is shows back up. I'm doing this as Dad.
If I try to delete it from the NAS

Why is the file considered write protected? it's 666.

I tried shutting down the NAS from frontview.
The NAS will not shut down gracefully. Raidar loses the connection.
I can ping the box

The box will not shut down. The power button is unresponsive. It looks like i will need to pull the plug on the box again.

Any great suggestions?
