LCTL-NODEMAP_DEL_OFFSET(8)

NAME
lctl-nodemap_del_offset - remove ID mapping offset from a nodemap

SYNOPSIS
lctl nodemap_del_offset or
lctl nodemap del_offset --name NAME

DESCRIPTION
nodemap_del_offset removes an identity mapping offset from a nodemap for the UID, GID and PROJID types.

OPTIONS

--name NAME
    The name of the nodemap to remove the offset from.

NOTES
Removing an offset from a nodemap does 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 chown(1), chgrp(1), and 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.

EXAMPLES
Remove the already existing offset from nodemap remotesite:
        # lctl nodemap_del_offset --name remotesite

AVAILABILITY
lctl nodemap_del_offset is part of the lustre(7) filesystem package since release 2.16.0
