That may be fine for most people, as that's apparently what the kernel developers expect, as well as the only offering for Fedora users. It's not so good for people with a tried and true multiboot creation, maintenance, backup and restore strategy based upon cloning/copying partitions and a minimal number of physical hard disks per system.
From the backup point of view, is more secure to use 2 HD, rather than only one. Because if You has only one HD, and it got mechanicals or controller (internal) problems, the backup of one partition in other of the same disk, goes useless.
Additional safety of more disks unless using RAID is an illusion, and then with RAID you're right back to the limit of 14. To get 28 and safety means you need 4 disks: 2 for each set of 14 partitions, and matching devices for the RAID1. Now with 4 disks you have 4 times the opportunity for hardware failure, and 4 times the cost.
If You use 2 Hard Disks, then the problem of the 15 partitions is resolved, because You can obtain 30 partitions from the 2 HDs.
30 takes 3 devices, because 15 is only the name of the last device, not the count, which is 14, because on sd[1-4] only 3 can have filesystems.
What makes you think 30 is enough? I have 42+, and don't want to buy 3 times as many disks and the larger power supplies to feed them, and the extra electricity/pollution to run them full time. My backups involve (small) part time usage disks, typically shared among multiple systems.
Sorry, but I do'nt speak anything about RAID1. It's Your illusion. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
