Sorry for my 2nd post in a day but I'm after some advice again. I have a server with 8 disks. Disk 0 is not RAIDed the others are. Disk is the system disk with /, swap, boot on. The OS is FC4. The RAID partition uses LVM and is about 1.8Tb, 1TB in use. I want to upgrade, or re-install with CentOS and I don't want to have to re-store all data on the RAID 5 volume but I am not sure that I can because the LVM will use files from the system disk. Am I going to be able to maintain my existing LVM volumes during the re-install? Is there a procedure to maintain LVM or store in after an install or upgrade? The system is backed but if I have to re-create the partitions and restore it will be off-line for several days and I would need to schedule it for a public holiday. Any advice.
