[gentoo-user] Raid1 fstab
Hello, background I mostly followed these guides to build a raid1 workstation using (2) 2T seagate drives: http://www.gentoo.org/doc/en/gentoo-x86+raid+lvm2-quickinstall.xml http://en.gentoo-wiki.com/wiki/Software_RAID_Install http://en.gentoo-wiki.com/wiki/RAID/Software Since I'm just using a very simple partion scheme raid 1(boot, swap, /) I decided to forgo LVM, for now. Maybe on the next install, I'll get Dale to coach me on LVM2 ? ;-) Both drives are identical (edited to fit gmane): Disk identifier: 0xab83344a Device Boot Start End Blocks Id System /dev/sda1 * 2048 526335 262144 fd Lraid auto /dev/sda2 52633610573823 5023744 fd Lraid auto /dev/sda3 573824 3907029167 1948227672 fd Lraid auto OK so my question is does this fstab look ok, workable? improvements? none/proc procdefaults 0 0 /dev/cdrom /mnt/cdrom autonoauto,rw,user 0 0 shm /dev/shm tmpfsnodev,nosuid,noexec 0 0 /dev/sdb1 /usr/local/video2 ext4defaults0 1 /dev/md1 /boot ext4noauto,noatime 1 2 /dev/md3 / ext4noatime 0 1 /dev/md2 swap swapdefaults0 0 I did not setup initramfs, as those steps where not part of the guides, but googling I did see many places where initramfs was suggested. thoughts and comments? http://en.gentoo-wiki.com/wiki/Initramfs It's my first gentoo software raid. My email is down; so only post to this list! hopeful this AM, James

My email is down; so only post to this list! hopeful this AM, James I don't use an initrd and my OS is on a RAID1-partition. Eg. that isn't necessary. About your /etc/fstab, I have some concerns. One of your RAID-devices is /dev/sda What is the other one? I hope it isn't /dev/sdb. If it is, you will have issues with the /usr/local/video2 mountpoint. I would suggest using a LABEL for that mountpoint to avoid any possible issues. Apart from that, it looks fine. Please ignore the error-message when rebooting/shutting down the system that /dev/md3 can't be stopped. (It is in use for the root-partition ( / ) -- Joost

I think you don't need to put swap on RAID0. Just make the swap (in fstab) with the same priority (pri=) like: /dev/sda2noneswapsw,pri=30 0 /dev/sdb2noneswapsw,pri=30 0 (of course, first stop md2, change the partition ids to 82, and then mkswap ...)
