Sharing a mounted tape library among multiple users

Requirements for sharing a mounted tape library among multiple users of the IBM Storage Archive on a Linux® system.

For a Linux user other than the user who mounted the tape library to access the mounted file system, add the following line to the /etc/fuse.conf file before issuing the ltfs command:

user_allow_other

To mount the library as a user other than a superuser, in addition to the above setting, add the -o allow_other option to the ltfs command as shown in the following example:

$ ltfs -o changer_devname=/dev/sg10 -o allow_other /mnt/ltfs

To mount the library as a superuser, the -o allow_other option is not required as is shown in the following example:

# ltfs /mnt/ltfs -o changer_devname=/dev/sg10

Note: The on-disk metadata storage feature is disabled by default. When this feature is enabled, the ability to mount tape libraries is restricted to the root user. For more information, see Metadata storage to understand the on-disk metadata storage mechanism and to learn how to share a library mounted by the root user among multiple users.
