[PVE-User] Mount ceph storage to replace vm image

[Mailing Lists]

Hi Eneko,

Thanks for your reply. I'm a little unsure how to replace my new vm with
the empty one I created. Using a regular file system like ext4 this is easy
as I can just cd to the mounted file system and move my image over the
empty one, but with the ceph object store I can't seem to find the mount
point or the image I need to replace?

I have 3 servers, each have 2 disks, here's an example from one of the
servers (ceph and proxmox are running on the same boxes):

/dev/sdb1                                  2.8T   82G  2.7T   3%
/var/lib/ceph/osd/ceph-1
/dev/sdc1                                  2.8T  102G  2.7T   4%
/var/lib/ceph/osd/ceph-4

If I look inside /var/lib/ceph/osd/ceph-1/current where I believe some my
data is, I see many _head directories with even more files inside:

/var/lib/ceph/osd/ceph-1/current# ls -l 9.da_head/ |head
total 813816
-rw-r--r-- 1 root root 4194304 Jan 24 06:50
rbd\udata.1598342ae8944a.00000000000000a3__head_C767A8DA__9
-rw-r--r-- 1 root root 4194304 Jan 31 06:36
rbd\udata.1598342ae8944a.000000000000123a__head_1FA2DDDA__9
-rw-r--r-- 1 root root 4194304 Jan 27 06:48
rbd\udata.16a7622ae8944a.00000000000000dd__head_ACDFF8DA__9
...

A little lost :)

Thanks
Marc
