Currently, users do not know when some pg do scrubbing for a long time.
I think whether we could give some warming if it happend (defined as
osd_scrub_max_time).
It would tell the user something may be wrong in cluster.

Hi,

Cache Tier readonly:

Hi,
I have a Ceph cluster with both ARM and x86 based servers in the same cluster.
Is there a way for me to define Pools or some logical separation that would
allow me to use only 1 set of machines for a particular test.
That way it makes easy for me to run tests either on x86 or ARM and do

You can define them via different crush rules, and then assign a pool to a
given crush rule. This is the same in practice as having a node type with
all SSDs and another with all spinners. You can read more about how to set

Hi,
Is there a celing on the number for number of placement groups in a
OSD beyond which steady state and/or recovery performance will start
to suffer?
Example: I need to create a pool with 750 osds (25 OSD per server, 50 servers).
The PG calculator gives me 65536 placement groups with 300 PGs

Oh I believe HP swapped cciss for hpsa (Smart Array) driver long ago… so maybe
only download cciss
The problem with using the hpsa driver is that I need to install RHEL 7.1 on a
Proliant system using the SmartArray 400 controller. Therefore, I need a
driver that supports it to even install RHEL 7.1. RHEL 7.1 doesn’t generically
recognize that controller out of the box.
