Re: Fresh install - all OSDs remain down and out

Hi desmond,
this seems to be much to do for 90 OSDs. And possible a few mistakes in typing.
Every change of disk needs extra editing too.
This weighting was automatically done in former versions.
Do you know why and where this changed or was i faulty at some point?

Hi Markus

You should define the "osd device" and "host" then make ceph cluster work.
Take the types in your map (osd, host, chasis.....root) to design the crushmap according to your needed.
Example:
​​
host node1 {
        id -1
        alg straw
        hash 0
        item osd.0 weight 1.00
        item osd.1 weight 1.00
}
host node2 {
        id -2
        alg straw
        hash 0
        item osd.2 weight 1.00
        item osd.3 weight 1.00
}
root default {
        id 0
        alg straw
        hash 0
        item node1 weight 2.00 (sum of its item)
        item node2 weight 2.00
}
​​Then you can use default ruleset. It is set to take the root "default".

Hi desmond,
this is my decompile_map:
root@bd-a:/etc/ceph# cat decompile_map
# begin crush map
tunable choose_local_tries 0
tunable choose_local_fallback_tries 0
tunable choose_total_tries 50
tunable chooseleaf_descend_once 1
tunable straw_calc_version 1

# devices

# types
type 0 osd
type 1 host
type 2 chassis
type 3 rack
type 4 row
type 5 pdu
type 6 pod
type 7 room
type 8 datacenter
type 9 region
type 10 root

# buckets
root default {
        id -1           # do not change unnecessarily
        # weight 0.000
        alg straw
        hash 0  # rjenkins1
}

# rules
rule replicated_ruleset {
        ruleset 0
        type replicated
        min_size 1
        max_size 10
        step take default
        step chooseleaf firstn 0 type host
        step emit
}

# end crush map
root@bd-a:/etc/ceph#

How should i change It?
I never had to edit anything in this area in former versions of ceph. Has something changed?
Is any new parameter nessessary in ceph.conf while installing?

Thank you,
  Markus

It seems that there no setting weight to all of your osd. So the pg stuck in creating.
you can use some command to edit crushmap for setting weight:

# ceph osd getcrushmap -o map
# crushtool -d map -o decompile_map
# vim decompile_map (then you can change the weight to all of your osd and its host weight)
# crushtool -c decompile_map -o changed_map
# ceph osd setcrushmap -i changed_map

Then, it should work in your situation.

Hi,

What's your crushmap show? Or command 'ceph osd tree' show.

Hi,
i have upgraded my hardware and installed ceph totally new as described in http://docs.ceph.com/docs/master/rados/deployment/
The last job was creating the OSDs http://docs.ceph.com/docs/master/rados/deployment/ceph-deploy-osd/
I have used the create command and after that, the OSDs should be in and up but they are all down and out.
An additionally osd activate command does not help.

Ubuntu 14.04.4 kernel 4.2.1
ceph 10.0.2

What should i do, where is my mistake?

This is ceph.conf:

[global]
fsid = 122e929a-111b-4067-80e4-3fef39e66ecf
mon_initial_members = bd-0, bd-1, bd-2
mon_host = xxx.xxx.xxx.20,xxx.xxx.xxx.21,xxx.xxx.xxx.22
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
public network = xxx.xxx.xxx.0/24
cluster network = 192.168.1.0/24
osd_journal_size = 10240
osd pool default size = 2
osd pool default min size = 1
osd pool default pg num = 333
osd pool default pgp num = 333
osd crush chooseleaf type = 1
osd_mkfs_type = btrfs
osd_mkfs_options_btrfs = -f -n 32k -l 32k
osd_mount_options_btrfs = rw,noatime,nodiratime,autodefrag
mds_max_file_size = 50000000000000


This is the log of the last osd:
