- Red Hat Enterprise Linux (RHEL) with the Resilient Storage Add-On
Useful References and Guides
This guide describes Red Hat's policies applicable to storage devices that are used to host a
gfs2 filesystem. Users of
gfs2 should adhere to these policies in order to be eligible for support from Red Hat with the appropriate product support subscriptions.
clustered LVM volume required for
gfs2 filesystem must be deployed on an clustered or shared LVM logical volume in order to receive support from Red Hat. Clustered or shared LVM volumes used for
gfs2 must be managed by:
- RHEL 6 and 7:
clvmdand have the clustered (
c) bit enabled on the LVM volume group.
- RHEL 8:
lvmlockdand have the shared (
s) bit enabled on the LVM volume group.
gfs2 integrates with
lvm2 to perform certain critical functions in failure scenarios, and expected behavior is undefined when the filesystem is not hosted on an LVM logical volume.

lvm.conffile when the system is a part of RHEL High Availability Cluster setup?

Red Hat support for storage solutions with
gfs2: Red Hat does not exhaustively define or list which storage solutions, products, or configurations can be used with
gfs2. Red Hat does not certify individual storage solutions or products for use with
gfs2. Red Hat's general policies in relation to RHEL High Availability storage compatibility apply to RHEL Resilient Storage as well.
