Try this lvcreate command instead: lvcreate --stripes 12 -l 864 -n lvdocs02 vgdocs02 I would use 12 stripes since that is the number of volumes you have in the group, therefore thats also the number of IOs you can have in flight at a time. I would also use the -l parameter over the -L and give it the number of Physical Extents (PE) you want the lv to use. It seems to be more consistant that way, and you get exactly what you asked for. Be aware that if you are going to be striping the lv like this, you are basically preventing youself from being able to grow the file system like you can with a non-striped lv. You would have to dump and restore the file system to a larger lv that you had created previously. -- Jay Brenneman ---------------------------------------------------------------------- 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
