I have a client using a ReadyNAS NV+ v2 on site with 4 x 600GB SAS,
The NAS is regularly rebooting with no reason, logs show backup issues (known) but no reason for the reboots,
Have had the user shut down the NAS, remove the power supply adn let it stand for five mnutes then power back up, no change still rebooted after a while. Reboots seems to be around 15 minutes apart.
Have had the user replace the network cable for a new one but this made no difference.
Have uploaded the logs with this,
If any one can shed any light, I would be grateful.
I have a zipped log but the post prevented it from being uploaded.

You shouldn't post it publicly. You can ask the mods ( @JohnCM_S or @Marc_V ) to analyze them for you. Upload the zip to cloud storage. Send the mods a PM (private message) using the envelope icon in the top right of the forum page. Include a download link in the PM.
Re: ReadyNAS Shares keeps disconnecting from network
Thanks for the reply, Since becoming aware of the issue, the temperature has remained steady at 37 degrees C, Can you advise how to investigate power supply issues? Access to the NAS has not been an issue only drive mapping access to shares on the NAS drops, which does not sound like a PSU problem?
It could also be something going wrong with the disks I guess. So you could test them in a PC with vendor tools (Seatools for seagate, lifeguard for western digital).
It is possible (but I think less likely) that something has gotten corrupted in the software, which is causing the system to crash. A factory default would clear that up. That will destroy all the data though, so make sure the client has a full backup before it is attempted. Note if the issue is hardware, the NAS probably won't run long enough to complete the backup.
Re: ReadyNAS Shares keeps disconnecting from network
Hi, thanks for getting back to me,
Will certainly ask the client if they can get a vacuum cleaner and remove all dust.
As the NAS has been fully accessible via the web GUI at any and all times (thus far) I am not certain of the power supply being an issue so the system board being faulty. A quick seach of the serial number shows the unit warranty having expired on 2016-06-30.
I am in the process of getting a replacement NAS.
One issue which has just appeared is using Windows File Explorer users are getting access denied messages, yet traversing the same folder from the web gui allows access to all folders.
Is there a possibility remove share access then reconfiguring it might resolve this issue?
Is there a documented guide you can point me to do do this?
TIA

That needs to be done carefully - you can damage the fan if you don't know what you are doing. You don't want air to spin the blades. General advice is to hold the fins of the fan before trying to vacuum or run compressed air through the air intake.

If they are using Windows 10, then likely SMB 1 has been disabled on their PCs. You can re-enable it in "turn windows features on and off".
Re: ReadyNAS Shares keeps disconnecting from network
Apologies, when the drives become inaccessible, this occurs every roughly quarter of an hour the only way currently is to soft restart the NAS via the web GUI,
IF the cleaning of the NAS becomes a need will ensure caution is exercised,
Checking with the client if 'SMB 1.0/ CIFS Client' access is enabled, though if the clients could always access was always available and this issue has started to occur with a higher frequency than before does this still sound like a simple SMB 1.0 setting is a solution?
Can you advise if removing the sharing on the NAS and then reinstating this could be a solution?

If PCs that could access the NAS before cannot access it at all now, then you should check if SMB 1.0 is enabled.
It won't solve the issue with PC dropping their connection to the NAS.
Re: ReadyNAS Shares keeps disconnecting from network
Hi,
Can confirm checked a client computer being affected and SMB1.0 is enabled,
SMB 1.0/CIFS Automatic Removal is also checked, could this be unchecked?
ALL clients are affected simultaneously, none exempt when the issue occurs. Once the NAS is soft restarted for a whil ALL clients can access the shares unitl the issue reoccurs.
NOTE: If I did not say then apologies but if I log on the web GUI i can traverse the data on the shares, and this is quick, not instant but quicker that through Windows File Explorer.
Will the logs give any more clues where the issue lise if this is happeing on the NAS?

When this is checked, then if a PC doesn't access the NAS (or another device that uses SMB 1.0) for 15 days, then Windows will disable the client. It would then need to be re-enable via "turn windows features on or off". If the client replaces the NAS with a newer model, then they should just leave the settings alone. But if the NAS ends up remaining in service for a while, then it'd be good to uncheck it.

That does point to an issue on the NAS.
You could try turning SMB off and then on again in the NAS, and see if that is a workaround you can use instead of the reboot. It won't fix the problem, but it would attempt to restart the SMB server in the NAS. It would be faster if it works.
Have you tried re-connecting to a NAS share using the command line on a PC? I suspect it will fail, but probably useful to to confirm.
You'd run CMD, and then enter
net use * /delete /y
net use t: \\nas-ip-address\sharename /user:admin nas-admin-password
using a real public sharename, ip address, and admin password of course. Be careful on the typing- particularly spaces and the slash direction.
The first command terminates any open SMB sessions; the second attempts to mount the share as drive letter T.

- NAS has been in service for years, deselecting this is unlikely to resolve the issue as I am more inclined to this being the NAS than a client issue.
BTW, there is another issue with this NAS that will need to be worked out soon.
- Strong moves towards the NAS being replaced as it is out of warranty, but need to find the resolution to the issue until that happens.

- Will this be per each share or can this (should this) be done globally?
Will try your suggestion regarding command line script and report back.
Question: Is the latency between file explorer and the speed accessing files/ folders on the web GUI a clue?
Can you please advise how to post logs to the mods?

You upload the full zip file into cloud storage (google drive, onedrive, dropbox, etc).
Then send a PM (Private Message) to the mods ( @JohnCM_S and @Marc_V ) asking them to take a look. You send a PM using the envelope icon in the upper right of the forum page.
Include a downloadable link to the logs in the PM.

I agree it's not your current problem. The automatic removal wouldn't disable network share access on all the PCs at the same time - and if the SMB 1.0 client were disabled on a PC, rebooting the NAS wouldn't restore access.

I would do it globally. I'm mot sure exactly how to do that an a v2 NAS (I don't own one, and the documentation doesn't include many screenshots). But in other ReadyNAS there is a way to turn the service off and then back on. You might need to renable it on all the shares after you turn it on.
The idea here is to see to see if the SMB service is hung on the NAS.
Re: ReadyNAS Shares keeps disconnecting from network
Hi,
The client has a high performance desktop computer which had SMB1.0/ CIFS Server enabled (now disabled, no clue as to why this had been enabled), this was turned off for the last few days and while off the NAS showed (and continues to show) none of the issues.
I am monitoring the NAS however as there have been no issues as had been happening it seems most likely there as a conflict from this computer.
Thank you for the support, it is appreciated,
