BeeGFS进程调优

对于二进制部署的 BeeGFS，均使用 systemd 管理进程

  • mgmtd
> /etc/systemd/system/beegfs-mgmtd.service.d/override.conf

[Service]
Nice=-20
IOSchedulingClass=realtime
IOSchedulingPriority=0
  • meta
> /etc/systemd/system/beegfs-meta.service.d/override.conf

[Service]
Nice=-20
IOSchedulingClass=realtime
IOSchedulingPriority=0
  • storage
> /etc/systemd/system/beegfs-storage.service.d/override.conf

[Service]
Nice=-20
IOSchedulingClass=realtime
IOSchedulingPriority=0
  • helperd
> /etc/systemd/system/beegfs-helperd.service.d/override.conf

[Service]
Nice=-20
IOSchedulingClass=realtime
IOSchedulingPriority=0

验证 nice 设置的方式（PRI 字段）

验证 ionice 设置的方式

> ionice -p $(pgrep beegfs-mgmtd)
realtime: prio 0

> ionice -p $(pgrep beegfs-meta)
realtime: prio 0

> ionice -p $(pgrep beegfs-storage)
realtime: prio 0

> ionice -p $(pgrep beegfs-helperd)
realtime: prio 0
