Hi,
I am having an unusual slowdown using VMware with ISCSI gws. I have two
ISCSI gateways with two RBD images. I have checked the following in the
logs:
Dec 24 09:00:26 ceph-iscsi2 tcmu-runner: 2019-12-24 09:00:26.040 969 [INFO]
alua_implicit_transition:562 rbd/pool1.vmware_iscsi1: Starting lock
In addition: I turned off one of the GWs, and with just one it works fine.
When the two go up, one of the images is changing the "active / optimized"
all time (where generates the logs above) and everything is extremely slow.
I'm using:
tcmu-runner-1.4
ceph-iscsi-3.3
ceph 13.2.7
Regards,
Gesiel
The root cause of this issue is the overhead added by the network ping
time monitoring feature for the mgr to process.
We have a fix that disables sending the network ping times related
stats to the mgr and Eric has helped verify the fix(Thanks Eric!) -

I have about 1TB of data in the pool default.rgw.logs.
What logs are stored in this pool and can they be safely deleted?
It's can be trimmed via `radosgw-admin usage trim`.
