On my 3.x OMV machine (which I have had fr a long time) - I decided to do the upgrade to 4.x.
I uninstalled all plugins (not running that many)
SSH's in as root
Ran command "omv-release-upgrade" and let run to completion (from 3.x to 4.1.12)
No major errors other than the python warning
Let system reboot
Wait until system is fully up
login in as admin
all looks good - until I go to;
Storage
File Systems
I see the OS partition - and all looks good
But - my storage volume shows all n/a's and a status of "missing" (Raid 5 array appears to be just fine under Raid Management)
Any thoughts as to what to look for. I vaguely remember reading something a while ago about a problem with certain Linux kernals and Western Digital WD30EFRX-68E drives - - of which I have 4 in my array)
Any advice greatly appreciated
TIA
