That kernel works with RHCS 2.5 and below. You need the rpms from that
or the matching upstream releases. Besides trying to dig out the
versions and matchin

'MAX AVAIL' in the 'ceph df' output represents the amount of data that can be
used before the first OSD becomes full, and not the sum of all free space
across a set of OSDs.

I too experienced this with that kernel as well as the elrepo kernel.

Hallo,
apologies for reviving an old thread, but I just wasted again one
full day as I had forgotten about this issue...
To recap, udev rules nowadays do not (at least in my case, I am
using disks served via FiberChannel) create the links
/dev/disk/by-partuuid that ceph-disk expects.

Hi *,
facing the problem to reduce the number of PGs for a pool, I've found
various information and suggestions, but no "definite guide" to handle
pool migration with Ceph 12.2.x. This seems to be a fairly common
problem when having to deal wit
I don't think it's hardware issue. All the hosts are VMs. By the way, using
the same set of VMWare hypervisors, I switched back to Ubuntu 16.04 last
night, so far so good, no freeze.

we're using debian with our own backported kernels and ceph, works rock

what you're describing sounds more like hardware issues to me. if you

The freeze is likely a kernel panic. Try testing different versions of the
kernel.

One month ago when I first started evaluating ceph, I chose Debian 9.3 as
the operating system. I saw random OS hang so I gave up and switched to
Ubuntu 16.04. Every thing works well using Ubuntu 16.04.
Yesterday I tried Ubuntu 17.10, again I saw random OS hang, no matter it's

That big fat warning was related to the note under your second quote:
"Note: Prior to QEMU v2.4.0, if you explicitly set RBD Cache settings
in the Ceph configuration file, your Ceph settings override the QEMU
cache settings."
Short story long, starting with QEMU v2.4.0, your QEMU cache settings

hi,
I'm a bit confused after reading the official ceph docu regarding QEMU
and rbd caching.
http://docs.ceph.com/docs/master/rbd/qemu-rbd/?highlight=qemu
there's a big fat warning:
"Important: If you set rbd_cache=true, you must set cache=writeback or
risk data loss. Without cache=writeback, Q
