[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
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 metadata pool id data pool id --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
... 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
[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.
