will leave the namespace below it inaccessible. For this reason, by
default it is only possible to create remote sub-directories off MDT0. To
relax this restriction and enable remote sub-directories off any MDT, an
- administrator must issue the command
- <literal>lctl set_param mdt.*.enable_remote_dir=1</literal>.</para>
+ administrator must issue the following command on the MGS:
+ <screen>mgs# lctl conf_param <replaceable>fsname</replaceable>.mdt.enable_remote_dir=1</screen>
+ For Lustre filesystem 'scratch', the command executed is:
+ <screen>mgs# lctl conf_param scratch.mdt.enable_remote_dir=1</screen>
+ To verify the configuration setting execute the following command on any
+ MDS:
+ <screen>mds# lctl get_param mdt.*.enable_remote_dir</screen></para>

<para condition='l28'>With Lustre software version 2.8, a new
tunable is available to allow users with a specific group ID to create
parameter to the 'wheel' or 'admin' group ID allows users with that GID
to create and delete remote and striped directories. Setting this
parameter to <literal>-1</literal> on MDT0 to permanently allow any
- non-root users create and delete remote and striped directories. For
- example:
- <screen>lctl set_param -P mdt.*.enable_remote_dir_gid=-1</screen>
+ non-root users create and delete remote and striped directories.
+ On the MGS execute the following command:
+ <screen>mgs# lctl conf_param <replaceable>fsname</replaceable>.mdt.enable_remote_dir_gid=-1</screen>
+ For the Lustre filesystem 'scratch', the commands expands to:
+ <screen>mgs# lctl conf_param scratch.mdt.enable_remote_dir_gid=-1</screen>.
+ The change can be verified by executing the following command on every MDS:
+ <screen>mds# lctl get_param mdt.<replaceable>*</replaceable>.enable_remote_dir_gid</screen>
