Virtual TapeServer 6.03.42 Operations and Administration Guide

Administrative Tasks | 143
Several scripts are available that clean up after files that were created and abandoned due to
system or application errors. These include the following:
• rmoldpipes
• rmoldbylist
•rmoldsync
• rmoldfilelist.pl
In addition, errors in processes such as cron can cause mail messages to accumulate in the
mail directories. If a mail transfer agent is configured and running on the VTS server but
forwarding for the root and bill accounts is not configured, mail can accumulate in the mail
folders.
Finally, if SecureVTS is enabled, the /var/log/te-server directory can accumulate files.
Maintaining GFS for VTS
The Global File System (GFS) is an advanced feature that allows Linux servers to
simultaneously read and write files on a single shared file system on a SAN. VTS is based on
Linux, and GFS enables multiple VTS servers to access a shared set of pools and virtual
tapes. The Event Management Service (EMS) can then automatically mount virtual tapes
from the GFS pools as if they were separately mounted. Here is an example GFS
configuration:
With GFS, all VTS servers connect to each other over Fibre Channel to the same storage
array, and GFS allows each VTS to access all vaults at the same time. If a server becomes
unavailable, other servers can still access the vaults.
