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.
I used kickstart, pxe, tftp and dhcp to manage a cluster of mail servers. Two disk 1U boxes too. /, swap, /var (logging was to a central log host).
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.
A scsi raid controller with write cache? Hardware raid definitely. Especially if the driver supports the write cache.
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.
swap should go on a raid1 device whether partition or swap file. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
