Data inlining is automatically enabled by default on all 8KB formatted nodepools for clusters running OneFS 9.3 and later, and does not require any additional software, hardware, or product licenses in order to operate. Its operation is fully transparent and, as such, there are no OneFS CLI or WebUI controls to configure or manage inlining. However, the following OneFS sysctl can be used to disable data inlining in an emergency situation. Use of this sysctl is only recommended under the direction and supervision of Dell technical support:
# isi_for_array sysctl efs.bam.data_inline.enable=0
Similarly, restoring this sysctl value to “1” (the default) will re-enable data inlining.
In order to upgrade to OneFS 9.3 and later and benefit from data inlining, the cluster must be running a minimum OneFS 8.2.1 or later. A full upgrade commit to OneFS 9.3 and later is required before inlining becomes operational.
Note: Existing files will not be inlined during the upgrade process as of OneFS 9.3 and later. This limitation will be addressed in a future release.
