One of the Linux (RHEL4) systems at work has about 3.5 TB of disk in a RAID configuration. Unfortunately, the guy who setup the system (not me) had apparently never heard of GPT before. So, he partitioned the RAID into two portions -- one of 2 TB, and the other 1.5 TB. Each of those partitions is managed by LVM.
Despite hours of searching, I am unable to figure out a way to convert these to one big 3.5 TB partition. The operating system is mostly installed on LVM-managed parts of the disk, so I can't destroy the partitions and redo them without reinstalling the OS.
The best part is that the system is 2,000 miles away. Fortunately, we recently installed a digital KVM switch to the system. We also have someone there that can manage to insert the installation CD. With the KVM I can reconfigure the RAID and reinstall the OS remotely.
By the way, if you are thinking of getting an Avocent KVM switch, and you want to use LDAP authentication -- well, you better have Active Directory, because Avocent's crappy software does not allow you to configure the LDAP authentication query. In addition, their tech support seems to be both clueless and illiterate.
