Hi ,
CRUSH map have two parameter are "min_size" and "max_size".
Explanation about min_size is "*If a pool makes fewer replicas than this
number, CRUSH will NOT select this rule*".
The max_size is "*If a pool makes more replicas than this number, CRUSH
will NOT select this rule*"
Default set

Dear cephers：
My cluster( 0.87) got an odd incident.
The incident is when I marked the default crush rule "replicated_ruleset"
and set new rule called "new_rule1".
Content of rule "new_rule1" is just like "replicated_ruleset". Only
difference is ruleset number .
After applied new map into crush th

The weight is reflect spaces or ability of disks.
For example, the weight of 100G OSD disk is 0.100(100G/1T).

Dear Cephers,
When a bucket created, the default quota setting is unlimited. Is
there any setting can change this？ That's admin no need to change bucket
quota one by one.

Hi all,
Try to use two OSDs to create a cluster. After the deply finished, I
found the health status is "88 active+degraded" "104 active+remapped".
Before use 2 osds to create cluster the result is ok. I'm confuse why this
situation happened. Do I need to set crush map to fix this problem？

Dear cephers,
Just upgrade radosgw from apache to civetweb.
It's really simple to installed and used. But I can't find any parameters
or logs to adjust(or observe) civetweb. (Like apache log). I'm really
confuse. Any ideas?
Best wishes,

Hi cephers,
Have anyone ever created osd with btrfs in Hammer 0.94.3 ? I can create
btrfs partition successfully. But once use "ceph-deploy" then always get
error like below. Another question there is no parameter " -f " with mkfs.
Any suggestion is appreciated.

Hi wah peng,
Just a thought.
If you have a large amount of OSDs but less pg number. You will find your
data write unevenly.
Some OSD have no change to write data.
In the other side, pg number too large but OSD number too small that have a
chance to cause data lost.

Hi ,
Looks like your cluster have warning message of "2 near full osd(s)".
Maybe try to extend osds first？

In the other side, if you have 1 OSDs but only set pg = 8.
That mean some disks have no chance to using.
