It appears that with --apparent-size, du adds the "size" of the
directories to the total as well. On most filesystems this is the
block size, or the amount of metadata space the directory is using. On
CephFS, this size is fabricated to be the size sum of all sub-files.

Hi all,
Does anyone know if RGW supports Keystone's PKIZ tokens, or better yet know
a list of the supported token types?

Take Greg's comments to heart, because he's absolutely correct here.
Distributed storage systems almost as a rule love parallelism and if you
have enough you can often hide other issues. Latency is probably the
more interesting question, and frankly that's where you'll often start

I'm not sure why you have six monitors. Six monitors buys you nothing
over five monitors other than more power being used, and more latency
and more headache. See

for

According to lrbd wiki it still uses KRBD (see those /dev/rbd/...
devices in targetcli config).
I was thinking that Mike Christie developed a librbd module for LIO.
So what is it - KRBD or librbd?

With a single osd there shouldn't be much to worry about. It will have to get
caught up on map epochs before it will report itself as up, but on a new
cluster that should be pretty immediate.
You'll probably have to look for clues in the osd and mon logs. I would expect

Hi Steve
Thanks for your answer. I don't have a private network defined.
Furthermore, in my current testing configuration, there is only one OSD,
so communication between OSDs should be a non-issue.
Do you know how OSD up/down state is determined when there is only one OSD?
Best,
Jeff

Do you have a ceph private network defined in your config file? I've seen this
before in that situation where the private network isn't functional. The osds
can talk to the mon(s) but not to each other, so they report each other as down
when they're all running just fine.

Using a mon_command in librados you can send a 'osd df' if you want to.
