Table C-21. Storage Device Information
Notes
For storage to be visible to the node, it may be necessary to load an appropriate device driver. If the
storage is not visible on the node, confirm that the device driver is loaded and that it loaded without
errors.
The two partitions (
You can display the storage device information at each node in your GFS cluster by running the follow-
ing command:
cat /proc/partitions
the names of the devices may be different on each node. If the output of the
command shows only entire disk devices (for example,
storage devices have not been partitioned. To partition a device, use the
C.6.2. Kernel Modules Loaded
Each node must have the following kernel modules loaded:
•
gfs.o
•
lock_harness.o
•
lock_nolock.o
• pool.o
C.6.3. Setup Process
The setup process for this example consists of the following steps:
1. Create pool configurations for the two file systems.
Create pool configuration files for each file system's pool:
and
pool_gfs02
poolname pool_gfs01
subpools 1
subpool 0 0 1
pooldevice 0 0 /dev/sda1
poolname pool_gfs02
subpools 1
subpool 0 0 1
pooldevice 0 0 /dev/sdb1
2. Use the
