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.3.2. Kernel Modules Loaded
Each node must have the following kernel modules loaded:
•
gfs.o
• lock_harness.o
• lock_gulm.o
• pool.o
C.3.3. 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/sda2
poolname pool_gfs02
subpools 1
subpool 0 0 1
pooldevice 0 0 /dev/sdb1
2. Create a pool configuration for the CCS data.
Create a pool configuration file for the pool that will be used for CCS data. The pool does not
need to be very large. The name of the pool will be
, followed by
alpha
poolname alpha_cca
subpools 1
subpool 0 0 1
pooldevice 0 0 /dev/sda1
3. Use the
pool_tool
n01# pool_tool -c pool_gfs01.cf pool_gfs02.cf alpha_cca.cf
Pool label written successfully from pool_gfs01.cf

4. Activate the pools on all nodes.
