I understand, but i delete the OSDs from CRUSH map, so ceph don't wait
for these OSDs, i'm right?

Hi,
just to clarify so I don't miss anything: you have two DCs and one of
them is down. And two of the MONs were in that failed DC? Now you
removed all OSDs and two MONs from the failed DC hoping that your
cluster will recover? If you have reasonable crush rules in place
(e.g. to recover from a failed DC) your cluster will never recover in
the current state unless you bring OSDs back up on the second DC.
That's why you don't see progress in the recovery process, the PGs are
waiting for their peers in the other DC so they can follow the crush
rules.
Regards,
Eugen

I was 3 mons, but i have 2 physical datacenters, one of them breaks
with not short term fix, so i remove all osds and ceph mon (2 of
them) and now i have only the osds of 1 datacenter with the monitor.
I was stopped the ceph manager, but i was see that when i restart a
ceph manager then ceph -s show recovering info for a short term of 20
min more or less, then dissapear all info.
The thing is that sems the cluster is not self recovering and the
ceph monitor is "eating" all of the HDD.

The recovery process (ceph -s) is independent of the MGR service but
only depends on the MON service. It seems you only have the one MON,
if the MGR is overloading it (not clear why) it could help to leave
MGR off and see if the MON service then has enough RAM to proceed
with
the recovery. Do you have any chance to add two more MONs? A single
MON is of course a single point of failure.

You could stop the MGRs and wait for the recovery to finish, MGRs
are
not a critical component. You won’t have a dashboard or metrics
during/of that time but it would prevent the high RAM usage.

mgr: fond-beagle(active, since 39s)
Your manager seems crash looping, it only started since 39s.
Looking
at mgr logs may help you identify why your cluster is not
recovering.
You may hit some bug in mgr.
Noup, I'm restarting the ceph manager because they eat all server
RAM and then i have an script that when i have 1GB of Free Ram
(the server has 94 Gb of RAM) then restart the manager, i dont
known why and the logs of manager are:

Ok i will do that... but the thing is that the cluster not show
recovering, not show that are doing nothing, like to show the
recovering info on ceph -s command, and then i dont know if is
recovering or doing what?
