What’s your pool configuration wrt min_size and crush rules?


Zitat von Amudhan P <amudhan83@xxxxxxxxx>:

Hi,

I am using ceph Nautilus cluster with below configuration.

3 node's (Ubuntu 18.04) each has 12 OSD's, and mds, mon and mgr are running
in shared mode.

The client mounted through ceph kernel client.

I was trying to emulate a node failure when a write and read were going on
(replica2) pool.

I was expecting read and write continue after a small pause due to a Node
failure but it halts and never resumes until the failed node is up.

I remember I tested the same scenario before in ceph mimic where it
continued IO after a small pause.

regards
Amudhan P
