Senior, Junior And The Programmer
The job:
A server with a 1.2 TB SATA RAID-5 is housing 15 paravirtualized Xen guests via local storage. Each one has at least one LV of 100 – 400 GB. Move them to an identical server with a more sensibly configured RAID without pissing off each user for more than 30 – 40 minutes. All [...]
