Hello All,
In the ceph quincy Not able to find rbd_mirror_journal_max_fetch_bytes config
in rbd mirror
i configured the ceph cluster almost 400 tb and enable the rbd-mirror in the
starting stage i'm able to achive the almost 9 GB speed , but after the rebalane
completed of the all the images . rbd-mirror speed got automaticily reduce to between 4 to
5 mbps.
in my primary cluster we are continuelsy writing the 50 to 400 mbps data but replication
speed only we get the 4 to 5 mbps. also we have the 10 Gbps replication network
bandwidth.
Note::- I also try to find the option rbd_mirror_journal_max_fetch_bytes but i'm not
able to find the this option in the configuration. also when i try to set from the command
line it's showing error like
command:
ceph config set client.rbd rbd_mirror_journal_max_fetch_bytes 33554432
error:
Error EINVAL: unrecognized config option 'rbd_mirror_journal_max_fetch_bytes'
cluster version
ceph version 17.2.5 (98318ae89f1a893a6ded3a640405cdbb33e08757) quincy (stable)
Please suggest any alternative way to configurre this option or how i can improve the
replication n/w speed.
