firstly, we need two logical volume: + ${src_lv} -- src logical volume: + - if have ${use_root_partition}, src_lv=/dev/mapper/os-${os}_${os_arch}_${os_version}_${use_root_partition} + - if no ${use_root_partition}, src_lv=/dev/mapper/os-${os}_${os_arch}_${os_version}_${timestamp} + ${boot_lv} -- boot logical volume: + - if have ${save_root_partition}, boot_lv=/dev/mapper/os-${os}_${os_arch}_${os_version}_${save_root_partition} + - if no ${save_root_partition}, boot_lv=/dev/mapper/os-${os}_${os_arch}_${os_version} + - if ${src_lv} not exists: + - if have ${use_root_partition}, exit 1. + - if no ${use_root_partition}, create ${src_lv}, and rsync the rootfs from cluster nfs server. + - if ${boot_lv} != ${src_lv}: + - if ${boot_lv} exists: delete it + - create ${boot_lv} as the snapshot of ${src_lv}. + - switch root to ${boot_lv}. + 3. boot the rootfs and execute the job. + ``` + +Demo usage: + ``` + - in 20210218, you submit a job-20210218.yaml, and you want to persist the rootfs data of + job-20210218.yaml so that it can be used by the subsequent jobs. + Then you need add the follow field in your job-20210218.yaml: + kernel_append_root: save_root_partition=zhangsan_local_for_iperf_20210218 + + - in 20210219, you submit a job-20210219.yaml, and you want to use the rootfs data of + job-20210218.yaml. + Then you need add the follow field in your job-20210219.yaml: + kernel_append_root: use_root_partition=zhangsan_local_for_iperf_20210218 + ``` + +Notes: + - obviously, ${save_root_partition} and ${use_root_partition} must be the same, and unique. + - you must 'save_root_partition' firstly, then you can 'use_root_partition'. otherwise, your job will fail. + +## work flow + +1. user submit job + job fields: + ``` + os: openeuler + os_arch: aarch64 + os_version: 20.03 + os_mount: local + kernel_append_root: use_root_partition=zhangsan_local_for_iperf_20210218 save_root_partition=zhangsan_local_for_iperf_20210219 + ``` 2. scheduler return the ipxe_str to testbox -
