Hello,
I was running OMV 0.3 since a long time. I finally decided to upgrade to 0.5, because of the new owncloud plugin.
Anyway, I was running the greyhole and MySQL plugins. I removed them with the clean script ( http://forums.openmediavault.org/viewtopic.php?f=12&t=2262 ).
The plugins are removed, but greyhole and MySQL are still active & running on the system (which is good). However, when I now reïnstall the mysql & greyhole plugins. Will they just start working with the active greyhole and mysql instances on the system, or will they try to reïnstall greyhole & MySQL?
