Nir Soffer 2017-03-02 14:46:00 UTC Doc Text Cause:
lvmetad daemon was dynamically activating logical volumes on multipath devices including guest logical volumes on top of RHEV logical volumes.

Consequence:
There are many issues caused by this auto activation:
- Increasing the number of devices on a hypervisor, slowing
down any operation that need to enumerate or scan devices.
- Failure to deactivate RHEV logical volumes since guest
logical volumes on top of them were active. This may lead
to data corruption.
- Errors when running lvm commands on the host, since guest
logical volumes may use physical volumes not available on
the hypervisor

Fix:
Vdsm disable now the lvmetad service.

Result:
Logical volumes are not activated dynamically. Vdsm activate and deactivate logical volumes as needed.

Consequence:

- Increasing the number of devices on a hypervisor, slowing

- Failure to deactivate RHEV logical volumes since guest

Fix:
Vdsm disable now the lvmetad service.

Result:
Logical volumes are not activated dynamically. Vdsm activate and deactivate logical volumes as needed.
Previously, the lvmetad daemon dynamically activated logical volumes on multipath devices including logical volumes created inside the virtual machine on top of Red Hat Virtualization Manager’s (RHV) logical volumes. This caused many issues, including the following:
- Increasing the number of devices on the Red Hat Virtualization Host, slowing
down any operation that needed to enumerate or scan devices.
- Failure to deactivate RHV logical volumes because the guest
logical volumes on top of them were active. This could lead
to data corruption.
- Errors when running lvm commands on the host, because guest
logical volumes may use physical volumes not available on
the Red Hat Virtualization Host.

In this release, vdsm disables the lvmetad service and logical volumes are no longer activated dynamically. vdsm activates and deactivates the logical volumes as needed.
