Re: [ceph-users] ceph-deploy can't generate the client.admin keyring

Alright, so I figured it out. It was essentially because the monitor’s main IP wasn’t on the public network in the ceph.conf file. Hence, ceph was trying to connect on an IP where the monitor wasn’t listening. Jean-Philippe Méthot Openstack system administrator Administrateur système Openstack

[ceph-users] ceph-deploy can't generate the client.admin keyring

keyring and it works flawlessly. ceph monitor logs don’t show any error and I am able to reach the monitor’s port by telnet. What could be causing this timeout? Jean-Philippe Méthot Openstack system administrator Administrateur système Openstack PlanetHoster inc

Re: [ceph-users] Ceph OSD node trying to possibly start OSDs that were purged

I did some digging around and yes, it is exactly as you said: systemd files remained to boot up the previous OSDs. We removed them and now it works properly. Thank you for the help. Jean-Philippe Méthot Openstack system administrator Administrateur système Openstack PlanetHoster inc. >

[ceph-users] Ceph OSD node trying to possibly start OSDs that were purged

could not find osd.213 with fsid 22800a80-2445-41a3-8643-69b4b84d598a Of course this fsid ID isn’t listed anywhere in Ceph. Where does ceph-volume get this fsid from? Even when looking at the code, it’s not particularly obvious. This is ceph mimic running on CentOS 7 and bluestore. J

[ceph-users] Ceph durability during outages

to work properly despite the outage, so what could have prevented it from functioning? Is it because there was only two monitors remaining? Or is it that reduced data availability message? In that case, is my erasure coding configuration fine for that number of nodes? Jean-Philippe Méthot Openstack

[ceph-users] Is it possible to hide slow ops resulting from bugs?

luster. Is there a way to deactivate this alert in particular so that ceph health can report actual issues and as a result, prevent Nagios from throwing alerts every time this bug happen? I would deactivate them only until this bug is fixed. Best regards, Jean-Philippe Méthot Openstack system adminis

[ceph-users] Ceph IO stability issues

will eventually hit a speed block because of either the CPUs or the network, but maximum speed is not my current concern here and can be upgraded when needed. I’ve been wondering, could these hiccups be caused by data caching at the client level? If so, what could I do to fix this? Jean-Philippe Méthot

[ceph-users] Erasure coding and the way objects fill up free space

OSD drive gets full, then CEPH would stop working, thus losing some unused space. Now, if I end up needing to replace some of the OSDs with bigger drives, will it take longer to have one OSD fill up, resulting in losing less space? Or will it end up being about the same? Jean-Philippe Méthot
