Hi,
I want install ceph in 3 machines. CEPH, CEPH-OSD-1 CEPH-OSD-2, each machines have 2 disk in RAID 0 with total 930GiB
CEPH is mon and osd too..
CEPH-OSD-1 osd
CEPH-OSD-2 osd
I install and reinstall ceph many times. All installation the CEPH don't get full partion space. Take only 1GB. How I change?
In first machine a have this:
CEPH$ df -Ph
