bally12345 Posted January 14, 2020 Share Posted January 14, 2020 (edited) 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 server-diagnostics-20200114-1815.zip Edited January 15, 2020 by bally12345 Quote Link to comment
JorgeB Posted January 14, 2020 Share Posted January 14, 2020 Don't see nothing special on the syslog, but server load is quite high, does it speed up if you stop all VMs/dockers? Quote Link to comment

Dockers were stopped and had just vm running. Disabled VM and DOCKER still the same. Can see CPU running around 15-20% Quote Link to comment
JorgeB Posted January 14, 2020 Share Posted January 14, 2020 Try rebooting in safe mode, re-start parity check and post new diags. Quote Link to comment
bally12345 Posted January 14, 2020 Author Share Posted January 14, 2020 is there a command I can run to restart into safe mode? Not got physical access at moment Quote Link to comment

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? Quote Link to comment

That means no GUI on a locally attached monitor. GUI access over the network via browser is available in all modes. Quote Link to comment
bally12345 Posted January 14, 2020 Author Share Posted January 14, 2020 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.

Did quick download check and was getting ~45MB/s in sabnzbdCould be all that time the issue was bad memory.I will do a few more checks and post back Sent from my SM-G973F using Tapatalk Quote Link to comment
bally12345 Posted January 14, 2020 Author Share Posted January 14, 2020 (edited) Nope slowed down again! Might have to do testing locally and try restarting network etc too just to rule out everything. Edited January 14, 2020 by bally12345 Quote Link to comment

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. Quote Link to comment

itimpi Posted January 15, 2020 Share Posted January 15, 2020 I would have expected to also see an entry for /mnt/cache. You might want to run it manually against that path to see what is reported. Quote Link to comment

JorgeB Posted January 15, 2020 Share Posted January 15, 2020 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. Quote Link to comment

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.

Going to try grab a magnifying glass Some good close up low angle photos from multiple directions can help. Cellphones can take remarkable macro shots through a good magnifying glass. 1 Quote Link to comment
