Hi List, yesterday i tried to install CentOS6 on Server bei Hetzner.de I noticed that Anaconda Installer is not possible to handle the 3TB Disks in Server when u try to Partition them. U can do only 3 normal partitions or u can do only 3 raid partitions, the SOLUTION is: Before U install Centos6 on the new naked server: a) Start Server in Rescue mode b) parted /dev/sda c) mklabel gpt ( Answer YES, you will do new disk label ) d) print ( look that all is fine? ) e) parted /dev/sdb f) mklabel gpt ( Answer YES, you will do new disk label ) g) print ( Answer YES, you will do new disk label ) h) q ( for quit ) Now go back to Hetzner Customer Menu, and activate VNC INSTALL Centos6 English 64 Bit Voila! now at the Part of Partitioning u say "CUSTOM LAYOUT" and you can do your own Layout as you like. Maybe this helps other ppl too. Marko ( from cloudy stormy rainy Hamburg Harbour )
