-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello,
I'm trying to create a 4-node Ceph Storage Cluster using ceph-deploy, following the official guide: http://docs.ceph.com/docs/master/start/quick-ceph-deploy/ I'm using debian wheezy 7 (x86_64) on all nodes and on each node, `uname -a` produces: "Linux nodeX 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux". I'm having trouble getting ceph-deploy to run. The ceph.log reads: [ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph/.cephdeploy.conf [ceph_deploy.cli][INFO ] Invoked (1.5.22): /usr/bin/ceph-deploy install node0 node1 node2 node3 [ceph_deploy.install][DEBUG ] Installing stable version giant on cluster ceph hosts node0 node1 node2 node3 [ceph_deploy.install][DEBUG ] Detecting platform for host node0 ...

[node0][ERROR ] RuntimeError: command returned non-zero exit status: 2 [ceph_deploy][ERROR ] RuntimeError: Failed to execute command: apt-key add release.asc So the problem lies with 'wget'. According to this thread ( http://www.linuxquestions.org/questions/debian-26/wget-certificate-error-4175495817/ ), there is a difference between the ubuntu and the debian versions of 'wget', they seem to be compiled and linked against different libraries. So on Debian the problem occurs, while on Ubuntu it does not. ( I did try to run `wget -O release.asc https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc` on Ubuntu 14.04 and it did finish successfully, while it fails on Debian ). So, my question is, what is the proper way of dealing with this error? As a workaround, I managed to get it to work (again, according to the same thread linked before): 1) visit 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=key /release.asc' using a browser, and export the certificate as ceph.pem 2) on every node run `# apt-get install openssl ca-certificates` 3) copy (scp) ceph.pem to /usr/share/ca-certificates/ceph.pem on every node 4) on every node run `# echo "ceph.pem" >> /etc/ca-certificates.pem` 5) on every node run `# update-ca-certificates` After these, I was able to run `wget -O release.asc https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc` on every node, successfully. Additionally, ceph-deploy seems to work fine now.
