Hello,
What exactly does the parameter 'bool exclusive' mean in the int
librados::IoCtxImpl::create(const object_t oid, bool exclusive)?
I can't find any doc to describe this :-(

From documentation in librados.h: it should be set to either either

Nice book, I don't have read yet all the book, but it seem to cover all ceph
features.
Good job !

yes, sure

I think the root-CA (COMODO RSA Certification Authority) is not available on
your Linux host? Using Google chrome connecting to https://ceph.com/ works
fine.
No, its a wget bug. I now switched to LWP::UserAgent and it works perfectly.

Thanks for the info. I'll try that for now and see if it helps.

Hi,
An engineer who worked for me a couple of years ago setup a Ceph cloud
running an old version. We are now seeing serious performance problems
that are affecting other systems. So I have tried to research what to do.
I have updated to 0.80.7 version and added more hardware and things are no
What version is this?
It's hard to tell from the logs below, but it looks like there might be a
connectivity problem? Is it able to exchange messages with the other
monitors?
Perhaps more improtantly, though, if you simply stop the new mon.f, can
mon.e join? What is in its log?

Dear cepher,
Currently I am working on crushmap to try to make sure the at least one copy
are going to different chassis.
Say chassis1 has host1,host2,host3, and chassis2 has host4,host5,host6.
With replication =2, it's not a problem, I can use the following step in rule
step take chasses1

It sounds a bit like the extra load on mon.e from the synchronization is
preventing it from joining the quorum? If you stop and restart mon.f it
should pick a different mon to pull from, though. Perhaps see if that
makes a different mon drop out? Then at least we'd understand what is
going
ceph version is 0.80.4
when add mon.f to {b,c,d,e}, mon.e is out quorum,
mon.b, mon.c, mon.d are electing in cycle(restart a new election after leader
win) .
so, i think current 4 monitors can exchange messages to each other
successfully.
In addtion, mon.f is stuck at state synchronizing,
With sufficiently new CRUSH versions (all the latest point releases on
LTS?) I think you can simply have the rule return extra IDs which are
dropped if they exceed the number required. So you can choose two chassis,
then have those both choose to lead OSDs, and return those 4 from the rule.

It's not entirely clear, but it looks like all the ops are just your
caching pool OSDs trying to promote objects, and your backing pool OSD's
aren't fast enough to satisfy all the IO demanded of them. You may be
overloading the system.

I ran into something similiar when messing with my test cluster -
basically, it doesn't like existing GPT tables on devices.
I got in the habit of running 'gdisk /dev/sdX' and using the 'x'
(expert) and 'z' (zap) commands to get rid of the GPT table
prior to doing ceph setup.
