|
|
> Manage persistent reservations (PR) on block devices or all PVs in a volume group.

|
|

|
|
- Start PR on all PVs in a VG with a local key (exclusive access by default):
|
||
|
|
|
||
|
|
`lvmpersist start --ourkey {{0x1234abcd}} --vg {{vg_name}}`
|
||
|
|
|
||
|
|
- Start PR for a shared VG (allow multiple hosts):
|
||
|
|
|
||
|
|
`lvmpersist start --ourkey {{0x1234abcd}} --access {{sh}} --vg {{vg_name}}`
|
||
|
|
|
||
|
|
- Stop PR on a VG and unregister the local key:
|
||
|
|
|
||
|
|
`lvmpersist stop --ourkey {{0x1234abcd}} --vg {{vg_name}}`
|
||
|
|
|
||
|
|
- Take over a local VG by preempting another host while starting PR:
|
||
|
|
|
||
|
|
`lvmpersist start --ourkey {{0xmy_key}} --removekey {{0xother_key}} --vg {{vg_name}}`
|
||
|
|
|
||
|
|
- Remove another host's key from a shared VG:
|
||
|
|
|
||
|
|
`lvmpersist remove --ourkey {{0xmy_key}} --removekey {{0xother_key}} --vg {{vg_name}}`
|
||
|
|
|
||
|
|
- Show registered keys and reservations for a VG:
|
||
|
|
|
||
|
|
`lvmpersist read --vg {{vg_name}}`
|
||
|
|
|
||
|
|
- Operate on specific devices instead of a VG:
|
||
|
|
|
||
|
|
`lvmpersist start --ourkey {{0x1234abcd}} --device {{/dev/sdX}} --device {{/dev/mapper/mpathY}}`
