Can't create filesystem

roswitina · 24. Juli 2014

Hello!

I use Proxmox 3.2. I will test OMV as KVM-Guest.

KVM Config for OMV:
1 GByte Ram
1 Disk (ide0) with 8 GB for System
3 Disk (virtio{0,1,2}) with 32 GB for Date

1) install the System on the ide-Disk (Version: 0.5.53)
2) log into the admin interface
3) show under Storage -> Physical disks: I saw 1 (one) ide-Disk and 3 (three) virtio-Disks
4) go to Storage -> Raid Management: I create a Raid5 (named Raid5) with the 3 virtio disks; after finished -> I saw one active Device /dev/md0 with 3 disks (/dev/vd{a,b,c})
5) go to Storage -> File systems: I will create a File system, but can't select a device (no drive listed)

what am I doing wrong?

Login as root on the OMV system. What is the output of:

cat /proc/mdstat
fdisk -l

Not sure why you can't but you can create the filesystem with:

mkfs.ext4 /dev/md0

Then you should be able to mount it in the web interface.

Thanks.

I installed Debian 7xx Net-ISO ans 1.07 Kralizec. Now i can create and mount the Raid5 Device.
