The vos lock command locks the Volume Location Database (VLDB) entry
for the indicated volume, blocking any operation that requires a write to

To unlock a single VLDB entry, use the vos unlock command. To unlock
several entries, or all locked entries in the VLDB, use the vos
Do not use this command in normal circumstances. It is useful for

Constructs a server ticket using a key from the local
/usr/local/etc/openafs/server/KeyFile file. The vos command interpreter presents it

The issuer must be listed in the /usr/local/etc/openafs/server/UserList file on the
