PROTOR Redhat : Using SMB mounted disk for PROTOR Archive

Redhat 7.2 has better integrated support for Samba (SMB) clients the previous Linux distributions used for PROTOR. It now is fairly simple for PROTOR to use an SMB mounted disk as an archivee disk using the following instructions.

As root create a mount point and change ownership to PROTOR root user.

          # mkdir /mnt/optical
          # chown protor /mnt/optical

Add an entry into /etc/fstab for the disk to mount via SMB in the form

  //server/disk/ /mnt/optical smb noauto,user,username=xxxx,password=xxx 0 0

   Where //server/disk/ is the SMB server and mount point of the disk.

Dependent on the share access provided by the server you may or may not need to include the username and password fields.
Since we require the PROTOR root user to be able to mount and dismount the archive disk then the task /usr/bin/smbmnt needs have the SUID bit set.

          chmod u+s /usr/bin/smbmnt

The PROTOR tasks to mount and dismount the archive disk ( arcmount and arcumount ) also need to be owned by root and have the SUID bit set. That is,

          chown root $PB_EXE/arcmount
          chown root $PB_EXE/arcumount
          chmod u+s $PB_EXE/arcmount
          chmod u+s $PB_EXE/arcumount

It should now be possible to mount and dismount the archive disk using the tasks arcmount and arcumount as the PROTOR user or by using the command:

          mount $ARCHIVE_MOUNT

You can check the SMB shares available on a server by using the command :

          smbclient -L server

You may be asked to provide a password dependent on the access to the share.
