[ceph-users] Unable to see LTTng tracepoints in Ceph
Hello Cephers, A very happy new year to you all! I wanted to enable LTTng tracepoints for a few tests with infernalis and configured Ceph with the -with-lttng option. Seeing a recent post on conf file options for tracing, I added these lines: osd_tracing = true osd_objectstore_tracing = true rados_tracing = true rbd_tracing = true However, I am unable to see LTTng tracepoints within ceph-osd. I can see tracepoints in ceph-mon though. The main difference with respect to tracing between ceph-mon and ceph-osd seems to be TracepointProvider and I thought the addition in my config file should do the trick but that didn't change anything. I do not know if this is relevant but I also checked with lsof and I see ceph-osd is accessing the lttng library as is ceph-mon. Did anyone come across this issue and if so, could you give me some direction on this? Thanks a lot for your help!

Re: [ceph-users] Cannot create Initial Monitor
Thanks a lot for your help, Varada. Since I was deploying Ceph via ceph-deploy
I could not see the actual errors. Low disk space led to a failure in creating
monfs. Things are now working fine.
Thanks,
Aakanksha

Could you try starting the monitor manually and see what the error is? Like
ceph-mon -i --cluster ceph &. Enable more logging (debug_mon).

Re: [ceph-users] Rados: Undefined symbol error
Hello Brad, When I type "which rados" it returns /usr/bin/rados. I am using Ubuntu 14.04. I follow these steps in installing ceph from source: 1. ./autogen.sh 2. Going to be using rocksdb, so: ./configure --with-librocksdb-static 3. make 4. sudo dpkg-buildpackage Then I use ceph-deploy to complete setup of the cluster and instead of ceph-deploy install, I type sudo dpkg -i -R .

Brad, Yes, you are right. Sorry about that! This is what I get when I try with the back ticks: $ `which rados` -v /usr/bin/rados: symbol lookup error: /usr/bin/rados: undefined symbol: _ZN5MutexC1ERKSsbbbP11CephContext $ strings `which rados`|grep "^ceph version" $ $ strings $(which rados)|grep "^ceph version" -A5 $ The latest command returns no results too.

Re: [ceph-users] Error while trying to create Ceph block device
Hello Somnath, Thanks for the quick response! I checked the versions on the client and the cluster machine. They actually had different versions of ceph installed: 0.94.2 on the cluster and 0.80.9 on the client. I made changes so that both of them have the same version of Ceph now. As for the librbd, librados packages, they seem to be having the same packages: librbd-dev, librbd1, librados2 and a few others. Is there any other way I could cross check?

I used to be able to do that earlier but it gives me a segmentation fault right now: *** Caught signal (Segmentation fault) ** in thread 7f49628f6840 ceph version 0.94.2 (5fb85614ca8f354284c713a2f9c610860720bbf3) 1: rbd() [0x595ffa] 2: (()+0x10340) [0x7f495cffc340] 3: (std::string::compare(char const*) const+0x1e) [0x7f495c21a17e] 4: (()+0x2d11e2) [0x7f495d6f11e2] 5: (()+0xa6c16) [0x7f495d4c6c16] 6: (main()+0x2952) [0x4c1132] 7: (__libc_start_main()+0xf5) [0x7f495b89fec5] 8: rbd() [0x4c6ee7] 2015-08-04 16:53:49.656920 7f49628f6840 -1 *** Caught signal (Segmentation fault) ** in thread 7f49628f6840 --- begin dump of recent events --- -15 2015-08-04 17:00:00.719905 7fce88413840 5 asok(0x327ed80) register_command perfcounters_dump hook 0x3280ef0 -14 2015-08-04 17:00:00.719922 7fce88413840 5 asok(0x327ed80) register_command 1 hook 0x3280ef0 -13 2015-08-04 17:00:00.719925 7fce88413840 5 asok(0x327ed80) register_command perf dump hook 0x3280ef0 -12 2015-08-04 17:00:00.719928 7fce88413840 5 asok(0x327ed80) register_command perfcounters_schema hook 0x3280ef0 -11 2015-08-04 17:00:00.719931 7fce88413840 5 asok(0x327ed80) register_command 2 hook 0x3280ef0 -10 2015-08-04 17:00:00.719932 7fce88413840 5 asok(0x327ed80) register_command perf schema hook 0x3280ef0 -9 2015-08-04 17:00:00.719938 7fce88413840 5 asok(0x327ed80) register_command perf reset hook 0x3280ef0 -8 2015-08-04 17:00:00.719941 7fce88413840 5 asok(0x327ed80) register_command config show hook 0x3280ef0 -7 2015-08-04 17:00:00.719942 7fce88413840 5 asok(0x327ed80) register_command config set hook 0x3280ef0 -6 2015-08-04 17:00:00.719946 7fce88413840 5 asok(0x327ed80) register_command config get hook 0x3280ef0 -5 2015-08-04 17:00:00.719947 7fce88413840 5 asok(0x327ed80) register_command config diff hook 0x3280ef0 -4 2015-08-04 17:00:00.719950 7fce88413840 5 asok(0x327ed80) register_command log flush hook 0x3280ef0 -3 2015-08-04 17:00:00.719951 7fce88413840 5 asok(0x327ed80) register_command log dump hook 0x3280ef0 -2 2015-08-04 17:00:00.719954 7fce88413840 5 asok(0x327ed80) register_command log reopen hook 0x3280ef0 -1 2015-08-04 17:00:00.722884 7fce88413840 10 monclient(hunting): build_initial_monmap 0 2015-08-04 17:00:00.723176 7fce88413840 -1 *** Caught signal (Segmentation fault) ** in thread 7fce88413840 Could anybody help me out here?

Re: [ceph-users] Configuring MemStore in Ceph
Hello Haomai, Thanks for your response. Yes, I cannot write more than 1GB of data to it. I am using the latest version deployed by ceph-deploy so I am assuming the fix must be a part of it. Also, while creating osds using ceph-deploy, I just use a local directory such as /var/local/osd0. Is there any particular step to change while creating the osd with memstore? Thanks a lot for your help!

Re: [ceph-users] Configuring MemStore in Ceph
Hello Haomai, The issue was with me not mentioning the value correctly in ceph.conf. I mistakenly used 5*1024*1024*1024 instead of the value 5368709120.

Maybe you could verify your osd config value via ceph daemon osd.0 config show | grep memstore Aakanksha -Original Message- From: Haomai Wang [mailto:haomaiw...@gmail.com] Sent: Tuesday, July 28, 2015 7:36 PM To: Aakanksha Pudipeddi-SSI Cc: ceph-us...@ceph.com Subject: Re: [ceph-users] Configuring MemStore in Ceph On Wed, Jul 29, 2015 at 10:21 AM, Aakanksha Pudipeddi-SSI aakanksha...@ssi.samsung.com wrote: Hello Haomai, I am using v0.94.2.

[ceph-users] Error while installing ceph built from source
Hello, I am trying to deploy a ceph cluster by compile from sources and I get an error with these messages: dpkg: dependency problems prevent configuration of ceph: ceph depends on ceph-common (= 9.0.0-943); however: Version of ceph-common on system is 9.0.0-1. ceph-common (9.0.0-1) breaks ceph ( 9.0.0-943) and is unpacked but not configured. Version of ceph to be configured is 9.0.0-1. . . . . Errors were encountered while processing: ceph ceph-dbg ceph-mds ceph-mds-dbg ceph-resource-agents I followed the steps from the documentation to build Ceph packages from source: 1. ./autogen.sh 2. ./configure 3. make -j6 4. sudo dpkg-buildpackage Now I am trying to deploy using the same procedure mentioned in ceph-deploy (with the exception of the ceph-deploy install ceph step): 1. ceph-deploy new hostname 2. sudo dpkg -i * (in the folder containing the .deb files) At this step I get the error that is pasted above. I was able to follow the same procedure without any issues on 2 other machines but I am not able to identify the root cause. Any help from the community is appreciated!

[ceph-users] Problem deploying a ceph cluster built from source
Hello all, I am attempting to install a ceph cluster which has been built from source. I first cloned the Ceph master repository and then followed steps given in the Ceph documentation about installing a Ceph build. So I now have the binaries available in /usr/local/bin. The next step is for me to deploy this build and I used ceph-deploy to do that: $ceph-deploy install -dev=master hostname This is where I get this error: [ceph_deploy.conf][DEBUG ] found configuration file at: /home/ssd/.cephdeploy.conf [ceph_deploy.cli][INFO ] Invoked (1.5.23): /usr/bin/ceph-deploy install --dev=master Hostname [ceph_deploy.install][DEBUG ] Installing dev version master on cluster ceph hosts Hostname [ceph_deploy.install][DEBUG ] Detecting platform for host Hostname ...

[Hostname][ERROR ] RuntimeError: command returned non-zero exit status: 2 [ceph_deploy][ERROR ] RuntimeError: Failed to execute command: apt-key add autobuild.asc I have checked with ssl certfificates and ca-certificates and they are the newest version. I have deployed a cluster with ceph-deploy earlier using the Quick installation guide and I got this certificate error then as well. But I used the -no-check-certificate flag then and it worked well. While using the ceph-deploy install command during the quick installation process, I used -no-adjust-repos and the same certificate verify error disappeared. But the same flag does not work here as ceph-deploy install -dev and -no-adjust-repos do not go together. I have two questions: 1. Is this the right way to deploy a ceph cluster built from source? I am asking since it is not mentioned directly as an end-to-end document as to how to deploy a ceph cluster which has been built from source 2. In cases where the ceph certificate is unverified, is it possible to issue something equivalent of the -no-check-certificate flag so that the installation does not stop because of an unverified certificate?
