Installing Centos6.3-minimal on RAID 1
hello all,
i want to install centos6.3 on a software raid1 on a Virtual machine for testing. i have two hdd disks and i want to accomplish the following: make raid1 with this 2 disks: /dev/sda /dev/sdb i have already partitioned theme as: /dev/sda1 200MB for boot /dev/sda2 17.8G for o\s /dev/sda3 2G for swap. and created my raid1 array fully synced. when the installation of centos6.3-minimal reaches the part of "Partitiong Type" it dosent give me the option to create\pick raid devices. it only lists: /dev/sda /dev/sdb 1. is this a limitation of Centos6.3 minimal? in short, what are the steps to install centos6.3 minimal on raid1? should i create the raid1 before or after? why does the installation wizard wont show anything about raid devices? i found: http://wiki.centos.org/HowTos/SoftwareRAIDonCentOS5 can i do the same steps without the GUI,i.e using Centos-minimal installation? see this one also: http://lists.centos.org/pipermail/ce...ly/114224.html guess i just download the full dvd .... |
You've got it wrong.
FIRST put the empty disks into a raid1 THEN create the partitions on the new software RAID device. ex. /dev/md0 Installing GRUB can get a little tricky because GRUB goes on the actual disk /dev/sda and perhaps /dev/sdb, not the /dev/md0 device. The Redhat/CentOS installer is different than Debian's. It's been too long since I've done a software RAID install with the CentOS one, so you may have to work at it a little more including using a live CD to set up the software RAID. |
Thanks for your reply , im experimenting with different raid\lvm setups:
what you have suggested is later addition of the kernel which support partitiong of raid devices (i.e parition md0 ..). ill get to that soon... i managed to prepare my partition layout and raided it as i described above using the centos6.3 regular dvd1 (not minimal). |
