Hi,
We're using a 24 server / 48 OSD (3 replicas) Ceph cluster (version 0.67.3) for
RBD storage only and it is working great, but if a failed disk is replaced by a
brand new one and the system starts to backfill it gives a lot of slow requests
messages for 5 to 10 minutes. Then it does become

Hi!
I want to receive email notifications for any ceph errors/warnings and for
osd/mon disk full/near_full states. For example, I want to know it immediately
if free space on any osd/mon becomes less then 10%.
How to properly monitor ceph cluster health?
Pavel.
It’s pretty basic, but we run this hourly:

I'm new to ceph in general but I'm wondering if anyone out there is using

specifically thinking of DCB-X support provided by the open-lldp package.
I'm wondering if there is any benefit to be gained by making use of the

Hi Greg,
How many monitors do you have?
1 . :)

depending on the process you went through to clean them up, but I

Yeah, too bad. I'm following the standard removal procedure in
If you never ran osd rm then the monitors still believe it's an existing

So, setting pgp_num to 2048 to match pg_num had a more serious impact than
