One thing to keep in mind is that the LVM support as supplied with SuSE does have a limit on the number of physical volumes than can be incorporated into a single VG. You can easily fix that by rebuilding LVM from source, but several folks have run up against that limit trying to provide really big chunks of space. If you use mod 9 or mod 27 devices, it may not matter, but you will see performance degradation on those big disks if everything is in the same directory and the heads have to move around to service different files. One comment from running TSM on AIX: you may see better behavior by having several smaller storage pools holding different directories, none bigger than the smallest physical volume available. >From the limited testing I've done, the Linux TSM server appears to like that as well. -- db ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
