Hello, I intend to run LVM on top on a software RAID5 on top of 8 IDE-disks (with 2MB cache) on 4 IDE-controllers (yes, I know it's not a reliable...) Kernel 2.4.25 is used. I'm going to use ReiserFS as filesystem, which uses a block size of 4k. If I've understand this correctly I'll need to use a PE-size of at least 32MB to be able to support LVs up to 2TB. How do I calculate the most optimal chunk-size on this system? Thanks in advance, /LM _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
