Hello,
this is my first posting to ceph-users mailgroup
and because I am also new to this technology please
be patient with me.
A description of problem I get stuck follows:
3 Monitors are up and running, one of them
is leader, the two are peons.
There is no authentication between the nodes yet.
Due to my try and error setup I'm afraid I build already
some zombies into my ODS map and
I am not able to get rid of them now.
First:
"ceph osd tree" reveals:
# id weight type name up/down reweight
-1 3 root default
-2 1 host arm01
1 1 osd.1 DNE
0 0 osd.0 DNE
-3 1 host arm02
2 1 osd.2 DNE
-4 1 host arm03
3 1 osd.3 DNE
Second:
a removal of any of those OSDs seems not be possible anymore:
"ceph osd rm osd.0" produces error "osd.0 does not exist".
Similar error messages occur when I try to remove remaining OSD's
osd.1, osd.2 and osd.3
Third:
The OSD processes on all three servers are NOT running.
Fourth:
OSD' configuration section defines:
[osd]
filestore xattr use omap= true
osd mkfs type = xfs
osd mkfs options xfs = -f
osd mount options xfs = rw,noatime
osd data = /var/lib/ceph/osd/$cluster-$id
osd journal = /var/lib/ceph/osd/journal
osd journal size = 100
[osd.1]
host = arm01
[osd.2]
host = arm02
[osd.3]
host = arm03
Fifth:
arch = armhf,
OS = debian 8,
ceph = 0.80.7
setup = due to absence of convenient setup scripts for armhf
architecture I set up ceph manually.
Question 1: how can I clean up my OSD map ?
Question 2: What does a column "reweight" wiht value "DNE" mean ?
"Does Not Exist" perhaps ?
Many thanks in advance,
Regards,
Martin.
