Maximum number of threads on Ceph-OSD nodes
Registered by
Mykola Golub
If you have a node with a lot of OSDs, you may be hitting the default maximum number of threads (e.g., usually 32k), especially during recovery.
It is recommended to Increase maximum number of threads to the maximum possible number of threads allowed (i.e. 4194303). This is controlled by sysctl parameter kernel.pid_max.
kernel.pid_max = 4194303
