Hi folks,
Some very basic questions.
(a) Can I be running more than 1 ceph cluster on the same node (assume that
I have no more than 1 monitor/node, but storage is contributed by one node
into more than 1 cluster)
(b) Are there any issues with running Ceph clients on the same node as the
other Ce
I'm seeing quite a few errors with ceph-deploy that makes me wonder if the
tool is stable.
For instance,
ceph-deploy disk list ; returns a partial set of disks, misses a
few partitions and returns incorrect partitions (for XFS type that aren't
listed by parted)
ceph-deploy osd prepare :/dev/sd{a}
Following up, I kept the default "ceph" name of the cluster, and didn't
muck with any defaults in the ceph.conf file (for auth settings).
Using ceph-deploy to prepare an OSD resulted in the following error. It
created a 1G journal file on the mount I had specified, and I do see a new
partition bein
Hi,
I'm trying to setup a 3-node ceph cluster using ceph deploy from an admin
machine (VM box). Firstly,
I did the following from the admin node:
1. ceph-deploy --cluster test new ceph-1 ceph-2 ceph-3 {3 monitors}
2. Edited the resultant test.conf file to put auth supported = none
3. Then did

Hi folks,
Just a bit confused about how I'd go about taking down a ceph-cluster. I
assume that unmounting all the clients (rbd, fuse, fs) and running
ceph-deploy purgedata for each of the nodes that make up the ceph storage
cluster should do the trick, correct?
However, executing ceph -s immediate

While trying to execute these steps in the ceph users guide, I get libceph
errors
no secret set (for auth_x protocol)
error -22 on auth protocol 2 init
Also, when providing the authentication keys (Step #3 below), I get the
following error:

Any ideas where
Hi folks,
I'm trying to get a ceph cluster going on machines running the SLES11 SP2
Xen. Ideally, I'd like it to work without a kernel upgrade (my current
kernel is (3.0.13-0.27-xen), because we'd like to deploy this on some funky
hardware (telco provider) that currently has this kenel version run
