Re: [ceph-users] How to do quiesced rbd snapshot in libvirt?

I am very sorry, but I am not able to increase log versbosity because it's a production cluster with very limited space for logs. Sounds crazy, but that's it. I have found out that the RBD snapshot process hangs forever only when QEMU fsfreeze was issued just before the snapshot. If the guest is

Re: [ceph-users] PGP signatures for RHEL hammer RPMs for ceph-deploy

This is odd. We are signing all packages before publishing them on the repository. These ceph-deploy releases are following a new release process so I will have to investigate where is the disconnect. Thanks for letting us know. On Tue, Jan 5, 2016 at 10:31 AM, Derek Yarnell

Re: [ceph-users] How to do quiesced rbd snapshot in libvirt?

Well, I believe the problem is no more valid. My code before was: virsh qemu-agent-command $INSTANCE '{"execute":"guest-fsfreeze-freeze"}' rbd snap create $RBD_ID --snap `date +%F-%T` and then snapshot creation was hanging forever. I inserted a 2 second sleep. My code after virsh

Hi Maruthi, happy to hear that it is working now. Yes, with the latest stable release, infernalis, the "ceph" username is reserved for the Ceph daemons. Best, Martin On Tuesday, 5 January 2016, Maruthi Seshidhar wrote: > Thank you Martin, > > Yes, "nslookup "

[ceph-users] Excessive OSD memory use on adding new OSD's, cluster will not start.

Hello all, medium term user of CEPH, avid reader of this list for the hints and tricks, but first time poster... I have a working cluster, been operating for around 18 months in various versions and decided we knew enough how it worked to depend on it for long term storage. Basic storage

[ceph-users] bad sectors on rbd device?

Hi List, I have an issue with an rbd device. I have an rbd device on which I created a file system. When I copy files to the file system I get issues about failing to write to a sector to sectors on the rbd block device. I see the following in the log file: [88931.224311] rbd: rbd0: write 8

[ceph-users] PGP signatures for RHEL hammer RPMs for ceph-deploy

It looks like the ceph-deploy > 1.5.28 packages in the http://download.ceph.com/rpm-hammer/el6 and http://download.ceph.com/rpm-hammer/el7 repositories are not being PGP signed. What happened? This is causing our yum updates to fail but may be a sign of something much more nefarious? # rpm -qp

[ceph-users] failure of public network kills connectivity

Hi I recently set up a small ceph cluster at home for testing and private purposes. It works really great, but I have a problem that may come from my small-size configuration. All nodes are running Ubuntu 14.04 and ceph infernalis 9.2.0. I have two networks as recommended: cluster network:

Re: [ceph-users] PGP signatures for RHEL hammer RPMs for ceph-deploy

It looks like this was only for ceph-deploy in Hammer. I verified that this wasn't the case in e.g. Infernalis I have ensured that the ceph-deploy packages in hammer are in fact signed and coming from our builds. Thanks again for reporting this! On Tue, Jan 5, 2016 at 12:27 PM, Alfredo Deza

Well, we figured it out :) This mailing list post fixed our problem http://www.spinics.net/lists/ceph-users/msg24220.html We had to mark the osds that were falsely reported as up, as down, and then restart all osd's Thanks! On Tue, Jan 5, 2016 at 6:43 PM, Mike Carlson

Hi Alfredo, I am still having a bit of trouble though with what looks like the 1.5.31 release. With a `yum update ceph-deploy` I get the following even after a full `yum clean all`. http://ceph.com/rpm-hammer/el6/noarch/ceph-deploy-1.5.31-0.noarch.rpm: [Errno -1] Package does not match intended

[ceph-users] Detail of log level

Dear cephers, Is there any documents can explain the detail of log level？ When using librados to access ceph the result is only display true and false. Can I get more specific detail like (source client IP、object name) from log？ If answer is yes then which log in subsystem I should add into
