"perf reset" on the admin socket. I'm not sure what version it went in
to; you can check the release logs if it doesn't work on whatever you
have installed. :)

Zheng, this looks like a kernel client issue to me, or else something
funny is going on with the cap flushing and the timestamps (note how
the reading client's ctime is set to an even second, while the mtime
is ~.63 seconds later and matches what the writing client sees). Any
ideas?

On Mon,
Scenario:
Openstack Juno RDO on Centos7.
Ceph version: Giant.
On Centos7 there isn't more the old fastcgi,
but there's "mod_fcgid"
The apache VH is the following:
ServerName rdo-ctrl01
DocumentRoot /var/www/radosgw
RewriteEngine On
RewriteRule ^/([a-zA-Z0-9-_.]*)([/]?.*)
/s3gw.fcgi?page=$1¶ms
Hi,
I am just wondering if anyone has any thoughts on the questions below...I would
like to order some additional hardware ASAP...and the order that I place may
change depending on the feedback that I receive.
Thanks again,

All,
I wish to experiment with erasure-coded pools in Ceph. I've got some questions:
1. Is FIREFLY a reasonable release to be using to try EC pools? When I
look at various bits of development info, it appears that the work is complete
in FIREFLY, but I thought I'd askJ

Hi experts,
Could you some guys guide me how to get ceph-extras packages for Centos7?
I try to install giant in centos7 manually, however, I get the latest
extras packages only for centos6.4 in repository.
BTW， Is the qemu aware to the giant? Shoud I get the dedicated one to the
giant?
Thanks in ad
Is there a way to 'reset' the osd perf counters?
The numbers for osd 73 though osd 83 look really high compared to the
rest of the numbers I see here.
I was wondering if I could clear the counters out, so that I have a
fresh set of data to work with.

I plan to use SSD Journal to improve performance.
I have one 1.2T SSD disk per server.
what is the best practice for SSD Journal ?
There are there choice to deploy SSD Journal

What versions of all the Ceph pieces are you using? (Kernel

Can you provide more details on exactly what the program is doing on

I have a couple of questions about caching:
I have 5 VM-Hosts serving 20 VMs.
I have 1 Ceph pool where the VM-Disks of those 20 VMs reside as RBD Images.
1) Can i use multiple caching-tiers on the "same" data pool?
I would like to use a local SSD OSD on each VM-Host that can serve

It is risky at best... I would not recommend it! The safe route is
For the first choice:
ceph-deploy osd create ceph-node:sdb:/dev/ssd ceph-node:sdc:/dev/ssd
i find ceph-deploy will create partition automaticaly, and each partition is 5G
default.
So the first choice and second choice is almost the same.
Compare to filesystem, I perfer to block device to get
