Our current recommended file system of choice is XFS. BTRFS is not supported and will result in a significant loss of performance. Moreover, SUSE does not recommend keeping variable on BTRFS and will create XFS volumes for /home and data. In this way there is no data loss on a rollback. (These recommendations also apply to Red Hat.)
| File System | Description | eDirectory Recommendation |
| ReiserFS | Was the default file system for SLES until 2006. Replaced by EXT3. | Not recommended for new installations |
| EXT3 | Journaled file system used as the default for many years. | Recommended: the conservative choice. |
| EXT4 | Block/inode allocator improvements. Not fully 64-bit. | Recommended: OES' default file system |
| BTRFS | Copy on write file system. | Not supported: for SLES 12 and later it is the default. |
| XFS | Scalable enterprise file system. | Highly recommended for all new installations. |
