Subject: [PATCH 13/25] lvconvert: use excl activation for conversion
|
||
|
|
|
||
|
|
Use properly exclusive activation when reactivating origin after
|
||
|
|
snapshot merge (since origin must have been previously also exlusively
|
||
|
|
activated).
|
||
|
|
|
||
|
|
Same applies when converting volumes to thin-pool or cache.
|
||
|
|
|
||
|
|
Previously used 'only' local activation incorrectly allowed local
|
||
|
|
activation of some targets (i.e. raid) - thus 'leaking' chance to
|
||
|
|
activate same device on another node - which can be a problem
|
||
|
|
for device types like raid.
|
||
|
|
|
||
|
|
