Hello,
I'm freaking out.
No problem with 3 2.5" (Seagate 500GB) hdds on my Asrock H87M PRO 4 and building a raid-5. Now I wanted to upgrade and deleted the 2.5" raid. Installed 3 3.5" hdds (Seagate 3TB) and I can build the raid but can't build the filesystem afterwards. After buildung the raid automatically a new filesystem (EXT4) is created which can't be mounted. This does not happen when building the raid-5 with the 2.5" hdds. I have to manually build a filesystem and mount it. Abolutely perfect but no chance with my 3.5" hdds.
Right now I'm building a new RAID-5 with 3x3TB 3.5" hdds but there already is a "ghost filesystem" (see attached file).
What could be the problem? And maybe you have an idea for a solution ;-))
Thanks a lot in advance for your help.
