Hi, cephers:
What's the purpose of using LogEvent with empty metablob?
For example in link/unlink operation cross two active mds,
when slave receives OP_FINISH it will write an ESlaveUpdate::OP_COMMIT
to the journal, then
send OP_COMMITTED to master. When master receives OP_COMMITTED it will
write an ECommitted to the journal then allow previously logged
journal to be trimmed.
Why are these two logevents necessary?
I guess they are originally used for a scene that crashes happen,
but in my opinion it seems not necessary. For example,
if cash happens, after failed mds are brought up again, in resolve
stage, master will resend OP_FINISH to slave, then things will
continue as expected.
Could anyone give some tips on this doubt?
Sincerely thanks!
Hi,
From a healty nautilus cluster version 14.2.9 on a CentOS7 i try to follow the upgrade procedure to the containerized octopus setup with cephadm.
* https://docs.ceph.com/docs/octopus/cephadm/adoption/
Everything step went fine until i wanted to adopt the osds, then i get a error. Does anybody have a idea, what my problem could be?
````````````````````

We're glad to announce the availability of the ninth and very likely the
last stable release in the Ceph Mimic stable release series. This
release fixes bugs across all components and also contains a RGW
security fix. We recommend all mimic users to upgrade to this version.
We thank everyone for making this release a possibility.
Notable Changes
---------------
* CVE-2020-1760: Fixed XSS due to RGW GetObject header-splitting
* The configuration value `osd_calc_pg_upmaps_max_stddev` used for upmap
balancing has been removed. Instead use the mgr balancer config
`upmap_max_deviation` which now is an integer number of PGs of deviation
from the target PGs per OSD. This can be set with a command like
`ceph config set mgr mgr/balancer/upmap_max_deviation 2`. The default
`upmap_max_deviation` is 1. There are situations where crush rules
would not allow a pool to ever have completely balanced PGs. For example, if
crush requires 1 replica on each of 3 racks, but there are fewer OSDs in 1 of
the racks. In those cases, the configuration value can be increased.
* The `cephfs-data-scan scan_links` command now automatically repair inotables
and snaptable.

Hi
Thanks for the quick response.
To be honest my cluster is getting full because of that trash and I am
at the point where I have to do the removal manually ;/.

Hey folks,
I keep getting ceph health warnings about clients failing to respond to cache pressure. They always refer to sessions from ganesha exports. I've read all threads regarding this issue, but none of my changes resolved it. What I’ve done so far:
Ganesha.conf:
MDCACHE {
Dir_Chunk = 0;
NParts = 1;
Cache_Size = 1;
}
Attr_Expiration_Time = 0 in every export
mds_cache_memory_limit = 17179869184 on MDS Servers
I even set “client_oc = false” on the ganesha server, but this doesn’t seem to be applied
My setup is ceph version 14.2.8 (All Server and clients. One active MDS. Ganesha 2.8.3 runs on a dedicated Server.
ceph daemon mds.<active_mds> dump_mempools (filtered out the empty pools):

Every hint how to resolve the issue are welcome. If more information is needed, I am glad to provide it.

Hi
Is there any new way to find and remove orphans from RGW pools on
Nautilus? I have found info that "orphans find" is now deprecated?
I can see that I have tons of orphans in one of our clusters. Was
wondering how to safely remove them - make sure that they are really
orphans.
Does anyone have a good method for that?
My cluster mostly has orphans from multipart uploads.
Kind regards / Pozdrawiam,

Hello All,
Reading the documentation I created a multisite with luminous version.
I would like to know if it sync in one way only.
Using s3cmd if I put a file in a bucket on the primary zone I can see the
file in the same bucket on the secondary zone.
If I put a file in the bucket on secondary zone I cannot see the file on
the primary.
Is this the correct behaviour ?
Thanks & Regards
Ignazio
