I've just installed OMV (0.4.10) successfully with 4x2TB RAID5 and LVM. After creating three logical volumes and adding file systems (ext4) I was able to successfully create shared folders. I then rebooted, everything was fine, mounted successfully, shared folders are available across the network (NFS & CIFS). HOWEVER, I am unable to create any additional shared folders. The dropdown for 'Volume' on the shared folder creation dialogue box is not populated. It briefly says 'loading' but remains empty so obviously I am unable to create new shared folders (and obviously it worked prior to the reboot). I'm new to OMV (not to Linux) but I'm not sure where to look for the problem. I can't see anything in the logs. I have recreated the problem in a Virtualbox install too with a similar setup (using much smaller disks for the RAID5 but otherwise nearly identical).
Any help appreciated
