Re: [ceph-users] iSCSI on Ubuntu and HA / Multipathing

Hi Edward, What "Red Hat Enterprise Linux/CentOS 7.5 (or newer); Linux kernel v4.16 (or newer)" means is that you either need to use RHEL/CentOS 7.5 distribution with a 3.10.0-852+ kernel or any other distribution with a 4.16+ upstream kernel. Regards, Frédéric. - Le 10 Juil 19, à

If you use the dashboard module and it's working now -- don't change because it's broken totally in Disco and later (ceph v13 as well). On 7/10/19 2:51 PM, Reed Dier wrote: It would appear by looking at the Ceph repo: https://download.ceph.com/ That Nautilus and Mimic are being built for

[ceph-users] Any news on dashboard regression / cython fix?

Anyone know when the dashboard module will be working on any of the current and newer distros? The dashboard module won't load / is totally broken on all distros shipping binaries with cython>0.29.   That dashboard module provides a big 'at a glance' help. The 'workaround' that I saw posted

It does not appear that that page has been updated in a while. The official Ceph deb repos only include Mimic and Nautilus packages for 18.04, While the Ubuntu-bionic repos include a Luminous build. Hope that helps. Reed > On Jul 10, 2019, at 1:20 PM, Edward Kalk wrote: > > When reviewing:

Once backfilling finished, the cluster was super slow, most osd's were filled with heartbeat_map errors. When an OSD restarts it causes a cascade of other osd's to follow suit and restart.. logs like.. -3> 2019-07-10 18:34:50.046 7f34abf5b700 -1 osd.69 1348581 get_health_metrics reporting 21

Hello, Has anyone else seen this? Basically I reboot a node and 2-3 OSDs on other hosts crash. Then they fail to start back up and have seem to hit a startup bug. http://tracker.ceph.com/issues/38724 What’s weird is that it seemed to be the same OSDs that

Re: [ceph-users] How does monitor know OSD is dead?

I don't know if it's relevant here, but I saw similar behavior while implementing a Luminous->Nautilus automated upgrade test. When I used a single-node cluster with 4 OSDs, the Nautilus cluster would not function properly after the reboot. IIRC some OSDs were reported by "ceph -s" as up, even
