.SH NAME
lctl-nodemap_del_offset \- remove ID mapping offset from a nodemap
.SH SYNOPSIS
.SY "lctl nodemap_del_offset"
or
.SY "lctl nodemap del_offset"
.BI --name " NAME"
.YS
.SH DESCRIPTION
.B nodemap_del_offset
removes an identity mapping offset from a nodemap for the UID, GID and PROJID types.
.SH OPTIONS
.TP
.BI --name " NAME"
The name of the nodemap to remove the offset from.
.SH NOTES
Removing an offset from a nodemap does
.B not
affect the UID, GID, or PROJID of any files that were previously created under
this nodemap. If these files are mapped into a different nodemap, then their
UID, GID, and PROJID must be changed on a trusted client with access to the
unmapped, canonical file system IDs using
.BR chown (1),
.BR chgrp (1),
and
.BR "lfs project" (1)
from the old offset range to the new offset. As such, removing an offset from a
nodemap should be avoided whenever possible.
.SH EXAMPLES
Remove the already existing offset from nodemap remotesite:
.RS
.EX
.B # lctl nodemap_del_offset --name remotesite
.EE
