I have attempted 5 or 6 times to update to OMV7 / bookworm. The upgrade path has not been successful for me and i switched to clean installation. Use a clean download of Rasbperry PI OS Lite and set up SD Card with it. It boots, I get OS set up including fan and expanding FS, I run OMV Script, everything installs and comes up great.
If I make a change -
add a plugin
authorize myself for SSH
set up shared folders
And reboot - it bricks. I have sat 15 minutes hoping it will start up - but it never does. I can power off, watch the drive boot for 45 seconds or less, then no drive activity - sometimes a flash here or there every 5 seconds or so. I can't SSH in. and website is not up.
I have tried eliminating plugins, i have tried only configuring SMB/CIFS to try and eliminate if it is a specific plugin - but regardless of my attempts. every time I get OMV set up and credentials created - if I reboot it, it bricks.
