I am a newbie to OMV and Linux ( Debian ). After having installed OMV for more than 30 times, now my OMV works fine. I would like to share my experiences and issues here, they are possibly incorrect or only happened to me.
1. When install OMV 5.x, if your DHCP doesn't support IPv6, installation will hang, you must click cancel before it detects IPv6. Why detect IPv6? Why don't make it easy ? such as give both manual and auto setup option in advance?
2. If your destination disk has a partition, installation will fail to create a partition for OMV OS and be in a YES/NO cycle. You have to restart your install from beginning. It's very ridiculous. If want to do automatically, why don't remove existing partition ? If can't, why don't launch a partition tool?
4. You must disable all the disks except OS disk for OMV installation, otherwise the installation will have 80% chance of failure.
5. If install OMV without network connection, will failed to download and install packages from Debian archive mirror. Extra plugin can't be installed properly without package . I didn't find any option to reinstall package in OMV GUI afterwards.
6. For ZFS plugin, needs extra commands to get ACL worked for a new disk pool.
