Hi there, I have 4 fiber channel disks, on which I intend to build a logical volume using lvm. Before creating the logical volume, I run an I/O test on the disks, which revealed that the disks each would do 10MBytes/sec I/Os. However, when I create a logical volume, spanning all 4 disks using RAID0, I realize that the transfer rate now drops. Instead (10 * 4)MB/s, I get something close to 30MB/s. Am I doing something wrong?!? My procedure to create logical volume: 1. Do fdisk on drive - do -o (DOS option). PS : setting the type to linux lvm(8e) results in errors on creating the logical volu7me - do pvcreate on the disk(s) - do vgcreate on all physical volumes requested - do lvcreate on created volume - mkfs.ext2 on logical volume - mount log. volume thanks for your time Innocent _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
