Description

The description on how-to configure DNE on page 98 of the Lustre manual needs to be corrected:

• In first box (paragraph) with heading 'Introduced in Lustre 2.4'
  the sentence
  • '... To relax this restriction and enable remote sub-directories off any MDT, an administrator must issue the command lctl set_param mdt.*.enable_remote_dir=1.'
  • have to be replaced with
    '.. To relax this restriction and enable remote sub-directories off any MDT, an administrator must issue the command lctl conf_param <fsname>.mdt.enable_remote_dir=1 on the MGS. For Lustre filesystem 'scratch', the command reads as lctl conf_param scratch.mdt.enable_remote_dir=1.
    To verify the configuration setting execute
    lctl get_param mdt.*.enable_remote_dir on any MDS'
• In second box (paragraph) with heading 'Introduced in Lustre 2.8'
  the sentence
  • ' ... Setting this parameter to -1 on MDT0 to permanently allow any non-root users create and delete remote and striped directories. For example:
    lctl set_param -P mdt.*.enable_remote_dir_gid=-1'
  • have to be replaced with
  • ' ... Setting this parameter to -1 on MDT0 to permanently allow any non-root users create and delete remote and striped directories. On the MGS execute
    lctl conf_param <fsname>.mdt.enable_remote_dir_gid=-1.
    For Lustre filesystem 'scratch' the commands expands to lctl conf_param scratch.mdt.enable_remote_dir_gid=-1.
    The change can be verified by executing lctl get_param mdt.*.enable_remote_dir_gid on every MDS. '
