oVirt Unlock Virtual Disks, VM and Snapshot

Beklenmedik durumlarda oVirt üzerinden vm‘ler ya da disk‘ler ya da snap‘ler lock duruma düşebilir. Bu durumu cockpit üzerinden gözlemleyebilirsiniz fakat çözüm için HostedEngine makinesine SSH atıp unlock_entity.sh scriptini kullanabilirsiniz.

Lock durumdaki vm, disk ya da snapshot‘ları aşağıdaki yöntemle consol üzerinden de tespit edebilirsiniz.

/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -q -t vm -c
/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -q -t disk -c
/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -q -t snapshot -c

Akabinde ilgili vm diskini unlock etmek için,

/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t vm UUID_OF_VM

Ya da tüm diskleri unlock etmek için,

/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t all

Genellikle tercih edilmemeli ama db(postgresql) üzerinden de işlem yapılabilir.

su - postgres
scl enable rh-postgresql95 bash
psql
\c engine
select snapshot_id,description,status from snapshots where status = 'LOCKED' and vm_id in (select vm_guid from vm_static where vm_name='');
select image_guid,imagestatus from images where vm_snapshot_id = '' and imagestatus != 1;
update snapshots set status = 'OK' where snapshot_id = '';
updates images set imagestatus = 1 where image_guid = '';
