Reset NAS without losing data

English Storage
1

Hi All

1st time posting

I have a TS 464 running QTS 5.2.9.3451 about 3 years old in Raid 5

2 x SSD 2TB for cache

4 x 16 TB storage

The NAS works and is accessible, stream media , Data etc.

But the GUI is running incredibly s..l..o..w and occasionally times out, trying to change any settings this is extremely frustrating.:angry:

I have reset it and there was a slight improvement, but nowhere near its normal performance

Would a restore factory defaults and format be beneficial,do I lose any data or is it retained and I just create new shares.

If I reinitialise with the hard drives removed be an option, and then install them in the correct order. Would the system see the config when it boots up.. I also have a back up .bin file if needed

Any suggestions would be appreciated

Thanks in advance

The os and everything is on the drives, so removing them for a reset would not do anything.

Cache is known to slow the system down, remove the cache and try again.

I hope you have good backups

Surely the cache would not affect the GUI interface :thinking:

Tranfers between folders and shares on the network are not affected, it only the GUI has the problem

Sluggish transfers, rebuilds and GUIs have been reported over the years..yes

Hello,

with my TS-264/TS-364 i have no problem.

But my system (with the apps) is on my SSD volume and my NAS has more RAM.

Unfortunately my NAS has no option to upgrade the RAM :disappointed_face:

This issue has only arisen in the last few weeks after I have creating a few VM, which I have since deleted.

So I am wondering if its a config problem in the system registry

If you look at the Resource Monitor, you should see an app using a lot of resources there.

And try disabling the SSD cache just to see what happens.

Hi dolbyman,

Is the “sluggishness” simply due to the utilization of cache SSDs or QNAP’s implementation?

I just integrated a Spare drive to my RAID 5 (from 5 HDD 14TB WD RED Plus to 6 HDD) and the migration / reclaiming took about 34 hours!

The transfer speeds were 50-60 Mb/s in average, whichI found were quite slow, compared to my NAS to NAS back-up transfer speed… does the SSD cache slow this process down?

Thanks in advance for your input.

VMs are extremely taxing on the system. Disable them as see how it affects your performance.

It is most likely the cache. Cache seems to be broken in QTS. It slowed a muchcmore powerful TVS-h1688X down.

Hi Dosborne, I have removed the VM app, and the system now only runs Plex

12

disabled the 2 ssd cache drives, made no difference

You mention the OS is on the drives, if that’s the case what happens if you start a device without any drives.

Surely the boot and on some config is in the bios ?

13

disabled but did not remove the SSD NVE cache .. no difference :thinking:

14

no difference with the cache disabled :roll_eyes:

Thought it maybe malware or virus, currently doing a scan.

6 hours in and only 16% completed

15

If only I could add more RAM :weary_face:

Please open a support ticket so our Support Team can assist you with further analysis. Also, could you let us know which applications you currently have installed? Thanks!

The NAS will start into setup, just as if you just bought it

I would highly recommend that you open an SSH shell and run the command “top”. This will show you your CPU load and processes.

The important thing to look at is not CPU usage percentage but CPU load. The load average value:

Load average is basically the number of threads in queue for the system. You have a quad core CPU with 4 threads. That means you can be running 4 threads at the same time. So if your load value shows anything much higher than 4, your system will be running VERY slow - especially if it is up at 20 or 30.

Things that can slow you down:

Qsirch when indexing
Multimedia Add-on when indexing
QuMagie when indexing
Raid rebuilds
Pool scrubbing

Anything that is indexing or messing with the file system will drive the load number higher. You should be able to identify the processes.

QNAP will have you star to shut down different processes to see which one is affecting you. What I would do is shut down everything from the App Center. Turn off everything you can. Then restart your NAS. Then when the NAS comes back up, turn your apps back on.

Just restarting doesn’t always work. Sometimes apps get some zombie threads that don’t get killed properly and they hang around and take up resources. Shutting the apps down kills all those threads. Rebooting with out shutting down brings your apps backup in the state they were before you rebooted - zombie threads and all.

Hi there.

personally I wouldn’t use the M2 SSD’s as cache. It would have been better to set these two as the system drive (ie OS and apps) then just use your HDD as storage. if the OS/Apps are on a fast m2 drives then your gui is faster.

I would definitely turn of cache and see what its like. Also are you using http or https for your console. what settings are you using in your System Administration?

Hi

Thx for the detailed reply, i have removed SSD cache and restarted, the GUI is still slow for the

File station Takes few minutes to populate

App Centre also take 3 o more minutes to populate or times out
