Hi everyone. I'm (very) new to PM and ceph. Some of the OSD's are down, and when I try to start them up, it says:
When I check df -h, it's not showing the drives are mounted (but fdisk -l is showing the disks as being available)
Question 1: How do I know which disks are supposed to be which? E.G. I have 5 disks in fdisk -l and I have 5 OSD's. How do I know if osd.1 is supposed to be /dev/sdb1 or /dev/sdf1?
Question 2: If I mount the wrong osd to the wrong drive, am I going to lose the data on that drive? E.G. osd.1 is supposed to be /dev/sdb1 but I mounted osd.1 to /dev/sde1
Code:
# service ceph start osd.1
/etc/init.d/ceph: osd.1 not found (/etc/ceph/ceph.conf defines mon.0 mon.1 mon.2 mds.0, /var/lib/ceph defines )Question 1: How do I know which disks are supposed to be which? E.G. I have 5 disks in fdisk -l and I have 5 OSD's. How do I know if osd.1 is supposed to be /dev/sdb1 or /dev/sdf1?
