lvmpersist
Manage persistent reservations (PR) on block devices or all PVs in a volume group. More information: https://manned.org/lvmpersist.
- 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}}
