Latest firmware is p20.00.07, and it appears you're running an HP firmware, still, strange issue, but try with LSI firmware

This looks like a connection problem, replace cables for disk6, also for cache device.

This is a disk problem, aka bad sector.

sde isn't mounting because the UD plugin, together with some others, didn't install properly, try re-downloading them: Mar 23 11:07:31 Draco root: plugin: installing: /boot/config/plugins/unassigned.devices.plg Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): /boot/config/plugins/unassigned.devices.plg:1: parser error : Document is empty in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): ^ in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): /boot/config/plugins/unassigned.devices.plg:1: parser error : Document is empty in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): ^ in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): /boot/config/plugins/unassigned.devices.plg:1: parser error : Document is empty in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): ^ in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): /boot/config/plugins/unassigned.devices.plg:1: parser error : Document is empty in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: Mar 23 11:07:31 Draco root: Warning: simplexml_load_file(): ^ in /usr/local/emhttp/plugins/dynamix.plugin.manager/scripts/plugin on line 216 Mar 23 11:07:31 Draco root: plugin: file doesn't exist or xml parse error

That doesn't mean you shouldn't, if nothing else at least update to latest RAID firmware, since it's using an ancient one, it might even detect the SSDs after that, though since trim won't work not the best place to use them anyway.

AFAIK you'll need a plugin like the dynamix system temp or IPMI plugin if the board has IPMI, but either one can't show you past temps.

Very unlikely, the temp sensor is inside the CPU. It only throttles during the overheat period, once the temperature decreases it will return to normal operation.

With Unraid each disk is an independent filesystem, so if the share spans multiple disks it will need to be snapshoted for each disk, you can do that easily with a script.

Controller is being detected correctly, though it is in raid mode, but no disks are detected, like no disks are connected, check if they are detected by the controller bios, if they aren't' it also won't be detected by Unraid, you should also flash it to IT mode with latest firmware.

With these LSI "lite" raid controllers it usually works the same, LSI MegaRAID controllers like for example 9260-8i can be different, since they use a different driver because they are more advanced raid controllers.

Disks should be detected even in raid mode, please post diagnostics: Tools -> Diagnostics, might be some clues there.

SFP+ optics aren't always compatible with all devices, I can tell you for example that the Avago AFBR-700SDZ-QL transceiver works well with both the ConnectX-2 and X-3, but no idea if they work with the Mikrotik switch.

Changing number of slots wouldn't make any difference for this, so most likely unrelated. You should recreate it, it's easy.

Yep. P.S. if the other disk is already failing, with read errors/pending sectors, don't enable turbo write, it will take longer but only parity and the disk being removed will be accessed.

I believe the script isn't working very well with current Unraid, if you want to do that and are semi-comfortable with the console you can do it manually: https://forums.lime-technology.com/topic/61614-shrink-array-question/?tab=comments#comment-606335

Yes

You need to re-created by

You have to specify the file, e.g. /system/libvirt/libvirt.img

Please don't crosspost, see your other thread.

Settings -> VM Manager Make sure advanced view is enable (top right)

It's used by a USB controller, should be fine to ignore.

Try in safe mode and/or unisnstall all plugins you don't really need, even if just temporarily, also stop all dockers you can, maybe you can find the culprit, I believe there are or were one or two dockers with memory leaks.

It does. That's expected since the errors are being correct so Memtest doesn't detect anything, DIMM still needs to be replaced, though it's unrelated to your current problems, if there is an uncorrectable error the server will halt.

Use it on the drive that was formatted.
