Total system slow down


Recommended Posts

I have been suffering from a slow down which I thought was due to a new crucial cache ssd but had a power cut and parity check running at 

10.5 MB/sec which is about 10th of its normal speed.

 

My system is showing less ram for about a week and I think the issue with 2 dimm slots for CPU 2 but not sure why or even if it has an affect on parity check and general system being really slow.

 

Does anything stand out in the diagnostics?

 

Many thanks

is there a command I can run to restart into safe mode? Not got physical access at moment

Not directly, but if you click on the flash on the `main tab and go down to the syslinux section and switch to the raw mode you can move the ‘menu default’ entry to be the part of the Safe Boot one you want.

Will Unraid OS Safe Mode (no plugins, no GUI) still give me access to webgui?

Still no access, will have to leave it until tomorrow.

I think it might be time for a update to date system. As iv started to see a few issues pop up.

First X5690 upgrade didn't work, 2 memory dimms stopped working now slow performance which is making me think they might a fault with the board.

Ok my bad, my VPN had disconnected I have access!
 
Still super slow.
 
Total size:12 TB
Elapsed time:2 minutes
Current position:1.06 GB (0.0 %)
Estimated speed:10.1 MB/sec
Estimated finish:13 days, 16 hours, 41 minutes
Sync errors corrected:0
So drove down to server, took out 4 sticks of 4GB memory 2 from each cpu so now down to 32GB

Loaded optimial default settings in bios to make sure nothing was changed by accident...

Looks like everything working again. Did quick download check and was getting ~45MB/s in sabnzbd

Could be all that time the issue was bad memory.

I will do a few more checks and post back

Does anyone know how I can manually invoke TRIM or check if TRIM has taken place on the SSD and is XFS fine for a 1TB

I am really sorry but we do not recommend the SSd's to be used in any servers.

Install the Dynamix SSD Trim plugin to run trim at regular scheduled intervals.

If you only have a single drive in the cache then XFS is fine, although if you ever add another drive to the cache it has to be switched to using BTRFS.

I have TRIM to run at 04:00 daily but I don't know if it has actually run on this drive.

You can always look in the syslog as there should be entries there when trim runs.

Jan 15 04:00:02 Server root: /etc/libvirt: 19.9 GiB (21366452224 bytes) trimmed on /dev/loop3
Jan 15 04:00:02 Server root: /var/lib/docker: 16.7 GiB (17922183168 bytes) trimmed on /dev/loop2

Looks like it run this morning but should I be seeing more?

Trim doesn't work currently on LSI SAS2 models, but even if it did it wouldn't work on that SSD, LSI requires SSDs with deterministic read zeros after trim, so you should connect it to an onboard SATA port instead.
650.01GB Trimmed. I think I might have a bent cpu pin on the board which has been causing all my headaches.

Going to try grab a magnifying glass and see if that is causing 2 dimms not to work on cpu and the 2 X5690s I have.
