G'day folks,
A client has indicated they want the 4x250GB SATA drives in their to-be-installed 7.1 (then 7.1.3) SME Server setup so that / is on a RAID6 partition. For them, the data redundancy is well worth the space and performance hits.
But, there doesn't seem to be any way to coerce SME 7.1 into such a setup. So, can anybody suggest a better approach than the following:
[list=1]
- Install a new (temporary) drive
- Boot CD with options "noraid nolvm"
- Perform a standard install to the temporary drive
- Reboot into RESCUE MODE
- Manually create RAID1 for /boot
- Manually create RAID0 for swap (may as well take advantage of the slight performance gain)
- Manually create RAID6 for /
- Create "new" / and /boot filesystems
- Transfer "old" filesystems to their new volumes
- Adjust /etc/fstab
- Adjust /boot/grub/menu.lst (if needed)
- Power down and remove temporary drive
- Reboot
[/list:o]
An alternative for step 6 would be to just use multiple swap partitions (one per drive). That way, the partition tables stay "in sync" and it's much easier to setup.
I had also considered implementing RAID10 but that would also require a temporary drive and is an even more complex process (although we would get almost as much redundancy and slightly better performance than RAID6).
Thanks for any suggestions.
