Create Logical Volumes for the SAP HANA Instance According to Your Sizing
lvcreate creates a new logical volume in an existing volume group. Depending on your storage setup you may
use different parameter to create the logical volumes. Think about stripping for example to increase the
performance. More detailed information can be found in the Storage Administration Guide for SLES 15.
The values used here, are examples. Check the SAP HANA documentation to choose the right values.
As the directory /usr/sap in our example is not shared with the operating system disk and we have enough
disk space here, we create a separate logical volume within the volume group system which was created
through YaST2 during the installation:
# lvcreate -L 50G -n lv_usr_sap system
Because we have three drives in our example, we can distribute the volumes SAP HANA data and SAP HANA
log into different volume groups and logical volumes. The SAP HANA shared volume is added to the system
volume group:
# lvcreate -L 96G -n lv_hana_shared system
# lvcreate -L 288G -n lv_hana_data vg00
# lvcreate -L 96G -n lv_hana_log vg01

3.8 Create filesystems
SUSE Linux Enterprise Server offers a variety of file systems from which to choose for different workloads. SAP
HANA needs certain criteria (files bigger than 2 GiB, fast file system with large files) which must be fulfilled. A
list of all supported filesystems can be found in the SAP Note 405827 - Linux: Recommended file systems .
In our example, we chose XFS for the file system.
The idea behind XFS was to create a high-performance 64-bit journaling file system to meet extreme
computing challenges. XFS is very good at manipulating large files and performs well on high-end hardware.
SUSE supports and includes XFS since SLES 8 as the default filesystem for partitions other than root.
More details are discussed in the SUSE Linux Enterprise Server Documentation section Storage administration
.
