Hello,
I am using a CEPH cluster. After monitoring it, I set:
ceph config set osd osd_memory_target_autotune false
ceph config set osd osd_memory_target 1G
Then restart all OSD services then do test again, I just use fio commands
from multi clients and I see that OSD memory consume is over 1GB.

Hello.
I will read more about it.
Thank you :)

Hello guys.
I see many docs and threads talking about osd failed. I have a question:
how many nodes in a cluster can be failed.
I am using ec 8 + 2(10 osd nodes) and when I shutdown 2 nodes then my
cluster crashes, It cannot write anymore.
Thank you. Regards

Hello.
I have 10 nodes. My goal is to ensure that I won't lose data if 2 nodes
fail.

Hello.
I get it. I will do a test and let you know.
Thank you much.
