Installation Manual

HP StorageWorks File System Extender Software installation guide for Linux 31
If you will assign additional file systems to the FSE disk buffer, run the following command for each of them:
Each command reports the properties of the newly created file system.
NOTE: To improve the performance of the FSE disk buffer, you can use Ext2 file systems for its storage
space. Ext2 file system are non-journaled and therefore faster than Ext3. In this case, in the above
command sequence, use the command mkfs.ext2 instead of mkfs.ext3.
Step 2: Creating HSM file systems
To create HSM file systems, proceed as follows:
1. Use the following command to create an HSM file system on top of the LVM logical volume fsefs_01:
In this example, the newly created HSM file system can store a maximum of 10 000 000 files, as the
same number of inodes are reserved on it. Consider the limitation on the number of inodes that can be
created on a file system with specific total size and specific block size.
You should use the number of inodes according to your HSM file system requirements, and the LVM
logical volume name according to your actual LVM volume configuration.
2. Create HSM file systems on all other LVM logical volumes that will be used for FSE partitions. Use
values according to your requirements and the particular purpose of HSM file systems in the FSE
implementation.
NOTE: The number of inodes on the file system cannot be changed once the file system has been put into
use.
The next section provides instructions on how to mount file systems for FSE databases and system files.
Mounting file systems for FSE databases and system files
The last step of the preparation procedure is to mount the file systems for FSE databases and system files.
Note that the file systems for the FSE partitions, that is HSM file systems, can only be mounted after the FSE
daemons have been successfully started.
To mount the necessary file systems, do the following:
1. Create the first of the three important FSE directories (and its parent directories):
2. Invoke the following command to retrieve the name of the device file. Use the symbolic link from the
step 1 of section ”Creating file systems on top of LVM logical volumes”:
The command generates an output similar to the following:
# mkfs.ext3 -b 4096 /dev/vg_fse/fsefri
# mkfs.ext3 -b 4096 /dev/vg_fse/fselog
# mkfs.ext3 -b 4096 /dev/vg_fse/fsediskbuf
# mkfs.ext3 -b 4096 /dev/vg_fse/fsediskbufNumber
# mkfs.ext3 -b 4096 -N 10000000 /dev/vg_fsefs/fsefs_01
# mkdir -p /var/opt/fse
# ls -la /dev/vg_fse/fsevar
