[ceph-users] Encryption
Hi! Maybe an FAQ, but is encryption of data available (or will be available) in ceph at a storage level? Thanks, Giuseppe ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
Re: [ceph-users] Wheezy machine died with problems on osdmap
Hi Sage, > What kernel version of this? It looks like an old kernel bug. > Generally speaking you should be using 3.4 at the very least if you > are using the kernel client. sage This is the standard Wheezy kernel, i.e. 3.2.0-4-amd64 While I can recompile the kernel, I don't think would be manageable having a custom kernel in production. Is there a way I can open a bug in debian asking for a backport of the patch? Thanks.

[ceph-users] Wheezy machine died with problems on osdmap
Hi all, my Debian 7 wheezy machine died with the following in the logs: http://pastebin.ubuntu.com/5981058/ It's using kvm and ceph as an rdb device. ceph version 0.61.7 (8f010aff684e820ecc837c25ac77c7a05d7191ff) Can you give me please some advices?

Re: [ceph-users] Python APIs
Hi John, apologies for the late reply. The librados seems quite interesting ... > Actually no. I'll write up an API doc for you soon. > > sudo apt-get install python-ceph > > import rados I wonder if I can ake python calls to interact with the object store (say: cephfs.open() mkdir() ) directly without involving radosgw. I guess the C libs are there if you can mount it using fuse ... Thanks. Cheers, Giuseppe ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
Re: [ceph-users] MDS dying on cuttlefish
... and BTW, I know it's my fault that I haven't done the mds newfs, but I think it would be better to print an error rather that going in core dump with a trace. Just my eur 0.02 :) Cheers, Giuseppe ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
Re: [ceph-users] MDS dying on cuttlefish
Hi Greg, just for your own information, ceph mds newfs has disappeared from the help screen of the "ceph" command and it was a nightmare to understand the syntax (that has changed)... luckily sources were there :) For the "flight log": ceph mds newfs --yes-i-really-mean-it Cheers, Gippa ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

Re: [ceph-users] MDS dying on cuttlefish
Hi Greg, > Do I correctly assume that you don't have any CephFS data in the cluster yet? The funny thing this was a fresh installation. Just for your information, ceph-deploy didn't worked for me and I had to do all the operations manually. I recreated one of the two ceph clusters with bobtail, same config, and worked like a charm immediately. > If so, I'd just delete your current filesystem and metadata pool, then > recreate them. > It should all be in the docs. :) Although empty, I did the ceph-osd --mkfs again, but with no luck. Also did the deletion of all the pools and recreated again (with a simple ceph osd create ) Regards, Giuseppe ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
[ceph-users] MDS dying on cuttlefish
Hi! I've got a cluster of two nodes on Ubuntu 12.04 with cuttlefish from the ceph.com repo. ceph version 0.61.2 (fea782543a844bb277ae94d3391788b76c5bee60) The MDS process is dying after a while with a stack trace, but I can't understand why. I reproduced the same problem on debian 7 with the same repository. -3> 2013-05-23 23:00:42.957679 7fa39e28e700 1 -- 10.123.200.189:6800/28919 <== osd.0 10.123.200.188:6802/27665 1 osd_op_reply(5 200.
