The recent thread on Anaconda and RAID10 made me start to think about
how to partition a server I'm about to set up. I have two 146GB SCSI
drives on an IBM x3550. It will be used as a build system. As such,
there is no critical data on these systems, as the source code will be
checked out of our source control system, and the build results are
copied to another system. I usually build my systems with Kickstart,
so if a disk dies, I can rebuild it quickly.
Given all that, how would you partition these disks? I keep going
back and forth between various options (HW RAID, SW RAID, LVM, etc.).
I guess speed is more important to me than redundancy. I'm tempted to
install the OS on one drive and use the entire second drive for data.
This way I can rebuild or upgrade the OS without touching the data.
But that will waste a lot of disk space, as the OS does not need 146GB.
The only thing I'm pretty sure of is to put 2GB of swap on each drive,
but after that everything is still in the air. I am looking for any
and all suggestions from the collective wisdom and experience of this
list.
Three raid1 sets:
raid1 #1 = /
raid1 #2 = swap
raid1 #3 = rest of disk on /home
for the simple fact that a dead disk won't bring down your system and
halt your builds until your rebuild the machine. But if you really only
care about max speed and are not worried about crashes & their
consequences, then replace the raid1 with raid0.
I have no reason for using LVM on boot/OS/system partitions. If I have
something that fills the disk that much, I move it to an other storage
device. In your case, striped LVM could be used instead of raid0.
