I'd have to think more about "proudest" but here is a recent one: Reshaped RAID by * LVM moving entire storage off to external iscsi SAN * wiping the controller config and recreating it from scratch in desired layout * migrating it back from SAN (before the whiners, it had backups and it was a node in cluster so even if it died no availability loss). Similar weird admin trick was * removing all of the nonessential LVs in LVM * creating a big fat file in /dev/shm (essentially ramdisk) * migrating storage to that file * shredding content of hard drives * voila, shredding drives of system without restarting and with still having ability to clean shutdown it.
