audience present here).
I've scrounged up 5 old Atom Supermicro nodes and would like to run them 365/7
for limited production as RBD with Bluestore (ideally latest 13.2.4 Mimic),
triple copy redundancy. Underlying OS

You need a partition on the SSD for the block.db (it's not a journal
anymore with blustore). You should loo

Hi Jan,
I think you're running into an issue reported a couple of times.
For the use of LVM you have to specify the name of the Volume Group
and the respective Logical Volume instead of the path, e.g.
ceph-volume lvm prepare --bluestore --block.db ssd_vg/ssd00 --data /dev/sda

Dear colleagues,
we build L3 topology for use with CEPH, which is based on OSPF routing
between Loopbacks, in order to get reliable and ECMPed topology, like this:
10.10.200.6 proto bird metric 64
nexthop via 10.10.15.3 dev enp97s0f1 weight 1
nexthop via 10.10.25.3 dev enp19s0f0 weight

Indeed. Deprecate it at the Nautilus release and drop it after N.

Hi.
We have the intention of using CephFS for some of our shares, which we'd
like to spool to tape as a part normal backup schedule. CephFS works nice
for large files but for "small" .. < 0.1MB .. there seem to be a
"overhead" on 20-40ms per file. I tested like this:

We'll be discussing SEO for the Ceph documentation site today at the
DocuBetter meeting. Currently when Googling or DuckDuckGoing for
Ceph-related things you may see results from master, mimic, or what's
a dumpling? The goal is figure out what sort of approach we can take
to make these results more

Hi Everyone.
Thanks for the testing everyone - I think my system works as intented.
When reading from another client - hitting the cache of the OSD-hosts
I also get down to 7-8ms.
As mentioned, this is probably as expected.
I need to figure out to increase parallism somewhat - or convince users
At the risk of hijacking this thread, like I said I've ran into this
