[Sudhaadm]

Hi all,
Thanks in advance.
While excecuting tar as a root user the below error has been occured.
a fkl1_am3/BAAa2693030/c677.vml 3 blocks
tar: couldn't get uname for uid 401
tar: couldn't get gname for gid 16
tar: couldn't get uname for uid 401

-----------------------
The file permissions(Instead of user and group name numeric no) also not in proper:
few files in that folder:
-rw-rw-r-- 1 3584 16 1100 Sep 18 2003 unmatched_neu_nets
-rw-rw-r-- 1 3584 16 1854835 Jul 15 12:24 wirelist

-rw-rw-r-- 1 3584 16 2222584 Aug 8 2002 wirelist_am2.o

Dear Sudhaadm,

Was there any removal of user / group is the system.

try

pwck --> password check

grpck---> group check

this will check for any inconistencies.

tar tries to get UID infromation from your system, its of no harm.

Hi,

This message simply means that UID 401 and GID 16 does not exists on this system. Allthough the ownner and group of these files from where these were backed up was with these IDs.

This is possible if you took backup on some other system and are restoring somewhere else or if you took backup on same system and restoring backup to onto same then some users and groups were deleted after backup.
This is why in case of user and group name in permissions it shows there numeric values as these users do not exist on this system.

HTH,
Devender
