On Thursday afternoon my NAS spat the dummy and my network shares stopped working, became painfully slow and the CPU is running at 100%

 

The two 3TB drives are showing as OK.

 

I put one of the drive into my computer and booted into ubuntu and it could not see the drives.

 

I then found some 1TB drives and put in the NAS and it is working perfectly.

 

I have then put the drive into a USB caddy and the NAS says it does not support that format.

 

I have put one of the 3TB drives back into the NAS and am able to copy stuff off the 3TB drive to a USB drive which is painfully slow.

 

At this rate it will takes weeks, the data itself is not hugely important but Nice to have, I would normally have a backup off all my data but I have been using that server for something else and Murphys law says something is going to go wrong now.

 

Any idea's on how to put the drive into a computer and recover the data at speed?

 

It appear that the synology OS has done a bad update as I was fine in the morning, works fine with a fresh install so all I can summise is an update gone bad.

 

Cheers

 

John

Did you have the two drives in RAID?
When the CPU was running at 100% did you see what processes were causing it and did you see any background tasks running?
Do you run any CPU intensive apps on the NAS like Plex Server?

I have the drives is RAID 1 but I cant see what process is causing it, it says something like user 87% system 13%

 

I have uninstalled all the apps and shut down what I can but still using 100%, I cant see what is actually causing it. From what I can tell you can not shut down a rogue process like you can with Windows.

 

I have also disabled all users other than the admin user and closed any open sessions.

Have you tried this?

I have a QNAP NAS so I can't be sure if it'll work, but have you tried connecting via ssh and entering the "top" command to get the processes with the highest CPU usage?

Thanks,

 

I have not seen that one, the one I saw did not have the additional commands, I can now see why Ubuntu would not have seen it.

 

I will try tomorrow.

So the NAS has stopped its hissy fit on its own and normal service has resumed.

 

I hate it when this happens.

All the vital stuff was multi backed up, this stuff was not, it was not the end of the world if I did not get it back.
