Initial GFS2 setup consists of the following tasks:
-
Setting up logical volumes.
-
Making a GFS2 files system.
-
Mounting file systems.
Follow these steps to set up GFS2 initially.
-
Using LVM, create a logical volume for each Red Hat GFS2 file system.
You can use init.d scripts included with Red Hat Cluster Suite to automate activating and deactivating logical volumes. For more information about init.d scripts, refer to Configuring and Managing a Red Hat Cluster.
-
Create GFS2 file systems on logical volumes created in Step 1. Choose a unique name for each file system. For more information about creating a GFS2 file system, refer to Section 3.1, “Making a File System”. You can use either of the following formats to create a clustered GFS2 file system:
mkfs.gfs2 -p lock_dlm -t ClusterName:FSName -j NumberJournals BlockDevice
mkfs -t gfs2 -p lock_dlm -t LockTableName -j NumberJournals BlockDevice
-
Command usage:
mount BlockDevice MountPoint
mount -o acl BlockDevice MountPoint
The -o acl-o aclgetfacl), but are not allowed to set them (with setfacl).
You can use init.d scripts included with Red Hat Cluster Suite to automate mounting and unmounting GFS2 file systems. For more information about init.d scripts, refer to Configuring and Managing a Red Hat Cluster.
