1. 확인하려는 VM의 디스크 정보를 이용해 vdisk_id 확인
$ acli vm.list
VM name VM UUID
01.OpenShift_DNS_8.11 cce1e476-495c-4aa4-befc-e52e6629d5e7
$ acli vm.disk_get 01.OpenShift_DNS_8.11 disk_addr=scsi.0 | grep vmdisk_uuid
vmdisk_uuid: "25465109-a2f4-468c-9446-b3e3bffc130a"
$ vdisk_config_printer | grep 25465109-a2f4-468c-9446-b3e3bffc130a -C5

2. vdisk의 사용 정보 확인
$ vdisk_usage_printer -vdisk_id=27929328
Egid # eids UT Size T Size Ratio Garbage Orphans T Type Replicas(disk/svm/block/rack) AES Egroup
!-1 0 0.00 KB 0.00 KB 100% 0.00 KB 0 none
> 복제된 디스크로 실제 유니크하게 점유한 chunk 정보가 없는 것으로 보임
3. snapshot tree 확인
$ snapshot_tree_printer | grep 27929328
[3][27929328(1,3,1,PD,ct=06/14-15:14:22)][27928575(2,2,1,rm,is,dt=6m)][27302480(3,1,1,rm,im,dt=125h49m)]
> 해당 디스크의 snapshot chain은 depth가 3으로 27302480 - 27928575 - 27929328로 연결되어짐
4. parent snapshot 정보 확인
$ vdisk_usage_printer -vdisk_id=27928575
Egid # eids UT Size T Size Ratio Garbage Orphans T Type Replicas(disk/svm/block/rack) AES Egroup
