Question & Answer

Question

Which file systems are recommended for DB2?

Answer

Platform	Operating System	File systems recommended
Linux	Red Hat Enterprise Linux (RHEL)	IBM General Parallel File System¹ (GPFS™) ext3 ext4 xfs⁵ VERITAS File System (VxFS) Network File System (NFS³) with IBM N-series Network File System (NFS³) with Network Appliance filers
Linux	SUSE Linux Enterprise Server (SLES)	GPFS ext3 ext4 xfs² VERITAS File System (VxFS) NFS³ with IBM N-series NFS³ with Network Appliance filers btrfs⁴
UNIX	AIX®	GPFS Enhanced Journaled File System (JFS2) NFS³ with IBM N-series NFS³ with Network Appliance filers VxFS
Windows	All Windows products	NTFS
Notes: ¹ See https://www.ibm.com/support/knowledgecenter/SSFKCN/gpfs_welcome.html for additional information about GPFS. ² Using xfs on SLES 12 requires kernel-default-3.12.32-33.1.x86_64.rpm or newer. ³ See http://www.ibm.com/support/docview.wss?uid=swg21169938 for details on which NFS versions are validated for use on various operating systems. ⁴ Only installation to default btrfs root partition is supported. Db2 containers on btrfs are not supported. ⁵In some cases, creating files on XFS in VM might fail with insufficient space error due to file system fragmentation. This problem is fixed in RHEL 8.3 ( https://access.redhat.com/errata/RHBA-2020:5137 ).
