-# Summary

+Summary +=======

-`os_mount` defines the mount method of testbox's root partition. +`os_mount` defines the rootfs type.

-It has the following optional values:

• • nfs
• • cifs
• • initramfs
• • container
• • local

+The below types are supported:

• • nfs
• • cifs
• • initramfs
• • container
• • local

Usage example:

• • submit iperf.yaml testbox=vm-2p8g os_mount=nfs
• • submit iperf.yaml testbox=vm-2p8g os_mount=cifs
• • submit iperf.yaml testbox=vm-2p8g os_mount=initramfs
• • submit iperf.yaml testbox=dc-8g os_mount=container
• • submit iperf.yaml testbox=vm-2p8g os_mount=local

-# Optional Values

-## Work flow when os_mount=local

-1. user submit job with os_mount: local

• • optional {kernel_append_root}:
• • save_root_partition: give an iconic string, then the root partition data used by this job will be retained.

•                       and you can use the root partition data of this job in the futher job by {use_root_partition}.
  

• • use_root_partition : give an iconic string, then the root partition data generated by the

•                       pervious job which has the {save_root_partition} field will be used.
  

• • root_partition_size: specify the size of root partition, *default is 10G*.
• • tips:

•  - value of {save_root_partition} and {use_root_partition} need to be iconic enough, uuid is recommended.
  

•  - value of {save_root_partition} and {use_root_partition} will be the suffix of logical volume.
  

• submit -m -c borrow-1h.yaml testbox=vm-2p8g os_mount=nfs
• submit -m -c borrow-1h.yaml testbox=vm-2p8g os_mount=cifs
• submit -m -c borrow-1h.yaml testbox=vm-2p16g os_mount=initramfs
• submit -m -c borrow-1h.yaml testbox=dc-8g os_mount=container
• submit -m -c borrow-1h.yaml testbox=taishan200-2280-2s48p-256g os_mount=local

+os_mount=local +==============

+`nfs`, `cifs`, `initramfs`, `container`, rootfs of them all are in memory. +So if you want to run your job in disk file system, you need to specify +`os_mount=local` in your job.yaml.

+BTW, the job's rootfs will be placed on a logical volume.

That level can be removed.

defaultly => by default
