RE: [SLE] raid5 disk expansion....

My hardware raid DOES allow me to do online expansion (incorporate new disk into an existing array). It's an MTI S200 SAN disk array and it allows online disk expansion. When we've done this with win2000, a reboot will then show the larger disk space. One does need "dynamic disk" in the orginal format though to do much with it. The problem with doing another disk array is that I'm basically losing another disk to the raid5, which I'm hoping to prevent. Any thoughts?

If the hardware has expanded the "virtual" disk it presents to the OS, you should be able to expand the partition, using something like fdisk or cfdisk. Then you can use the filesystem tools to expand the file system (for example resize_reiserfs, resize2fs, xfs_growfs or whatever you use)
