I agree. For the existing stable series the distribution support should be
continued.
But for new releases (infernalis, jewel...) I see no problem dropping the older
versions of the distributions.

Hello,
what is the „size“ parameter of your pool?
Some math do show the impact:
size=3 means each write is written 6 times (3 copies, first journal, later
disk). Calculating with 1.300MB/s „Client“ Bandwidth that means:
3 (size) * 1300 MB/s / 6 (SSD) = 650MB/s per SSD
3 (size) * 1300 MB/s / 30
,
But my question is why speed is divided between clients?
And how much OSDnodes, OSDdaemos, PGs, I have to add/remove to ceph,
that each cephfs-client could write with his max network speed (10Gbit/s ~
1.2GB/s)???

I am naive for this, no idea how to make a configurations or where I can
starts? based on the 4 options mentioned.
Hope you can expound it further if possible.
Best regards,

Hi,
I just noticed a strange behavior on one OSD (and only one, other OSDs on the
same server didn’t show that behavior) in a ceph-cluster (all 0.94.2 on Debian

The OSD started to accumulate slow requests, a restart didn’t help.

Hi,
Can someone give an insights, if it possible to mixed SSD with HDD? on the
OSD.
you’ll have more or less four options:
- SSDs for the journals of the OSD-process (SSD must be able to perform good on
synchronous writes)
- an SSD only pool for „high performance“ data
- Using SSDs for the
Hi,
When rebooting one of the nodes (e. g. for a kernel upgrade) the OSDs
do not seem to shut down correctly. Clients hang and ceph osd tree show
the OSDs of that node still up. Repeated runs of ceph osd tree show
them going down after a while. For instance, here OSD.7 is still up,
