изменить макет логического тома (Change logical volume layout)
Примечание (Note)
This previous command syntax would perform two different
operations:
lvconvert --thinpool
LV1 --poolmetadata
LV2
If LV1 was not a thin pool, the command would convert LV1 to a
thin pool, optionally using a specified LV for metadata. But, if
LV1 was already a thin pool, the command would swap the current
metadata LV with LV2 (for repair purposes.)
In the same way, this previous command syntax would perform two
different operations:
lvconvert --cachepool
LV1 --poolmetadata
LV2
If LV1 was not a cache pool, the command would convert LV1 to a
cache pool, optionally using a specified LV for metadata. But,
if LV1 was already a cache pool, the command would swap the
current metadata LV with LV2 (for repair purposes.)
