pvfs2-chmod – modify permissions on files in OrangeFS volumes

Synopsis

pvfs2-chmod [-v] mode filename(s)

Description

The pvfs2-chmod utility modifies the permission bits on the OrangeFS files specified. The mode is specified as a three or four digit octal number in the conventional manner.

The options are as follows:

-v

Print version number and exit.

Environment

PVFS2_DEBUGFILE

If set to the path of a local file, redirect debug output to it.

PVFS2_DEBUGMASK

Set the OrangeFS debug mask.  Possible masks are documented in pvfs2-set-debugmask(1).

PVFS2TAB_FILE

If set, the full pathname for an alternate pvfs2tab file

Files

/etc/pvfs2tab

Examples

Prevent other users from accessing a file.

pvfs2-chmod 600 /mnt/foo

Allow the owner and users in the file's group to read and modify the file and other users to only read the file.

pvfs2-chmod 664 /mnt/foo

Caveats

This utility does not support symbolic permissions like the chmod(1) utility.

Note that because OrangeFS is a network file system, any user with access to the network may be able to circumvent file permissions.
