Re: [ceph-users] mon service failed to start

Could the problem be related with some faulty hardware (RAID-controller, port, cable) but not disk? Does "faulty" disk works OK on other server? Behnam Loghmani wrote on 21/02/18 16:09: Hi there, I changed the SSD on the problematic node with the new one and reconfigure OSDs and MON service

Ben, first of all thanks a lot for such quick reply! I appreciate a provided explanation and info on things to check! I am new to all that that including InfluxDB that's why I used wrong influx cli to check if there are actual data is coming. But

Marc Roos wrote on 13/02/18 00:50: why not use collectd? centos7 rpms should do fine. Marc, sorry I somehow missed your question. One of the reason could be that collectd is a additional daemon whereas influx plugin for ceph is just an additional part of the already running system (ceph).

Re: [ceph-users] "Cannot get stat of OSD" in ceph.mgr.log upon enabling influx plugin

Forgot to mentioned that influx self-test produces a reasonable output too (long json list with some metrics and timestamps) as well as there are the following lines in mgr log: 2018-02-19 17:35:04.208858 7f33a50ec700 1 mgr.server reply handle_command (0) Success 2018-02-19 17:35:04.245285

Dear Ceph users, I am trying to enable influx plugin for ceph following http://docs.ceph.com/docs/master/mgr/influx/ but no data comes to influxdb DB. As soon as 'ceph mgr module enable influx' command is executed on one of ceph mgr node (running on CentOS 7.4.1708) there are the following

[ceph-users] mgr[influx] Cannot transmit statistics: influxdb python module not found.

Dear all, I'd like to store ceph luminous metrics into influxdb. It seems like influx plugin has been already backported for lumious: rpm -ql ceph-mgr-12.2.2-0.el7.x86_64|grep -i influx /usr/lib64/ceph/mgr/influx /usr/lib64/ceph/mgr/influx/__init__.py /usr/lib64/ceph/mgr/influx/__init__.pyc

[ceph-users] restrict user access to certain rbd image

Hello! I wonder if it's possible in ceph Luminous to manage user access to rbd images on per image (but not the whole rbd pool) basis? I need to provide rbd images for my users but would like to disable their ability to list all images in a pool as well as to somehow access/use ones if a ceph

[ceph-users] problem with automounting cephfs on KVM VM boot

Hello! I need to mount automatically cephfs on KVM VM boot . I tried to follow recommendations mentioned at http://docs.ceph.com/docs/master/cephfs/fstab/ but in both cases (kernel mode or fuse) as well as by specifying mounting command in /etc/rc.local it always fails to get mounted cephfs
