I installed OMV on hp dc7900 with 8GB ram. The installation finished successfully. OVM also worked for about ten minutes. Then OVM stuck on the HD access led always on. I thought that the HDD on which I installed OMV was faulty.
I changed 3 hd but the behavior was always the same. I tried to install ubuntu on the same machine and it worked without giving any problems. So it looks like the problem is OMV. Any idea?
