I've been struggling with my OMV install, with unionfs, snapraid. Honestly I'm not even sure how to phrase some of my questions. Since I believe my issues are revolving around unionfs and snapraid, I decided I'd try to post this in the plugins forum...
OMV 4, latest release.
4x4TB disks, that I pooled in Unionfs as a single volume "media".
Presently it has 7.99 Tb free out of almost 11.
I also have snapraid with 3 drives being content, and 1 being parity.
I have a few sharedfolders I set up on device "media", which is the name of my drive pool in UnionFS.
Under the Union Filesystem tab, it only lists 3 drives instead of 4 for some reason. First, since the 4th drive is parity for snapraid, should that been in the pool to begin with?
If I try to re-add the 4th drive to the pool, will it erase my information already on the pool?
That leads me to my second problem, which I discovered last night while trying to move a lot of files around. it appears that although I selected "existing path, most free space" policy, it is only storing information on 1 of the 3 drives. As I got a disk full error during an rsync. When I looked at the filesystem tab, it showed only 1 of the pool drives full, and the other two with barely anything on them.
I'm afraid to just go playing around with things, as I have already transferred a fair amount of data to the system. if I play with the pool system, like trying to change the policy on the pool, will that loose data, or if I break the pool itself and try to setup a new one, what will happen to the data stored on the volumes.
Lastly, is there anything I need to do to stop using snapraid, besides disabling the plugin in OMV? Something is faulty with my configuration as I cant scrub the disks, so i want to set it up again from scratch. Does anyone know of any guides or threads that describe the process of stopping it? I know there are content, and .lock files on the drives when I got to the /srv/drives... should I erase those manually from the command line, or will disabling the plugin remove them automatically.... etc...
Thanks for any help from anyone...
