Full Discussion: Nobody user group in Linux
Operating Systems Linux Nobody user group in Linux Post 302813839 by alister on Tuesday 28th of May 2013 08:13:49 AM

As root, can you cd into that directory and ls its contents? If so, root has access (as expected).

Adding username1 to the nobody group won't make any difference since the group has no permissions for that directory.

"taking backup" is vague and unhelpful. You should specify the exact commands used.

VGCFGRESTORE(8) 					      System Manager's Manual						   VGCFGRESTORE(8)

NAME
vgcfgrestore - restore volume group descriptor area SYNOPSIS
vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName DESCRIPTION
vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and archive files of VolumeGroupName. OPTIONS
-l | --list -- List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore Vol- umeGroupName. -f | --file filename -- Name of LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfg- backup. See lvm for common options. REPLACING PHYSICAL VOLUMES
vgdisplay --partial --verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to restore the volume group's metadata. SEE ALSO
