Description

Hello Developers

It would be really nice if you can setup an alert when the system has less open file descriptors or max_threads,pid_max value in the underlying osd operating system.

under /etc/sysctl.conf

vm.max_map_count = 12407310
kernel.pid_max = 4194303
fs.file-max = 19709928

under /etc/security/limits.conf

  • soft nproc 65535
  • hard nproc 65535
  • soft nofile 65535
  • hard nofile 65535

This is a very general problem and comes when you scale up your Ceph cluster or if your OSD node has more OSD's ( osd > 20 )

For more details , read this email thread.
