reboot - once restarted OMV6 should now be running - open a web-browser to your lockerstor and you should get the login page - login using the default admin account ( username admin password openmediavault) then refer to the OMV docs for how to proceed for setting up the RAID array on the lockerstor HDDs, creating users and shares etc
install Plex media server
don't do this UNTIL AFTER you have OMV6 installed, raid arrays and shares configured etc

reboot - you should be able to log in to Plex on port 32400 ( https://<hostname>:32400 ) - refer to the Plex docs for how to proceed to configure it
fixing intermittent ICRC errors on /dev/sdb
in the system logs could see intemittent issues on /dev/sdb ( ICRC errors - which are a link crc error ) when running 'sudo dmesg | grep -i sata'.
Seemed specific to the 2nd bay (sdb) ONLY, bay 1 ( sda ) was fine
I went into BIOS setup and under 'chipset SATA' tried changing
'agressive LPM mode' from 'enabled' (default) to 'disabled'
for each drive:
'SATA hot plug' from 'enabled' to 'disabled'
'mechanical presence' from 'enabled' to 'disabled'
Unfortunately on reboot this causes the 2nd drive to DISAPPEAR in the bios - so had to turn back on hot plug and presnce, leaving ONLY agressive LPM disabled
However whilst on that BIOS page I noticed the BIOS itself claims each port is only 3gbps sata - however linux is negotiating 6gbps. The chipset itself is good for 6gbps - but it's quite likely there's a design issue with the drive backplane (noise) that caused them to limit speed to 3gbps to get rid of errors!!!
to force 3gbps need to edit the kernel boot options :
sudo nano /etc/default/grub
find the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet"
change it to: GRUB_CMDLINE_LINUX_DEFAULT="libata.force=3.0"
if you want to disable spectre/meltdown mitigations at the same time ( decreases security, but improves performance )
instead change it to: GRUB_CMDLINE_LINUX_DEFAULT="libata.force=3.0 mitigations=off"
and then update grub via 'sudo update-grub'
after rebooting 'sudo dmesg | grep -i sata' should show link is now 3gbps
[ 1.984659] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 320)
[ 1.988644] ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 320)
there is a tiny impact on raid0 speed at the lower link speed ( r/w speed drops from 400mb/s to about 370mb/s ) - however this is still MUCH faster than the 2.5gbe port can deliver data so it's not really an issue
