Homework and Emergencies Emergency UNIX and Linux Support AIX : Create LV with poor man stripe Post 302418017 by bakunin on Sunday 2nd of May 2010 12:08:35 PM

You say you are using LUNs out of a SAN: in this case it is irrelevant if you employ some striping algorithm in creating LVs or not. The SAN will distribute your disk accesses physically to several disks anyway.

Quite contrary, you could (very unlikely, but the possibility is non-zero) run into problems trying to stripe yourself when using an already striped medium: because of "Moiré"-like (interference) effects the diverse levels of striping could cancel out one another and change your pattern of disk access to the adverse.

I hope this helps.

NAME
gnome-disks - the GNOME Disks application SYNOPSIS
gnome-disks [OPTIONS] DESCRIPTION
gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks and block devices. The Disks application is single-instance. What this means is that if the application is not already running when the gnome-disks command is invoked, it will get launched and the command invocation will block until the application exits. Otherwise the existing application instance will be used and the gnome-disks command will exit immediately. OPTIONS
The following options are understood: --block-device DEVICE Switches to the Disks application and selects the block device given by DEVICE (for example, /dev/sda). --block-device DEVICE --format-device [--xid WINDOW-ID] Shows the "Format Volume" dialog for the block device given by DEVICE (for example, /dev/sdb1). If WINDOW-ID is given, makes the dialog transient to the given XID. --help Prints a short help text and exits. AUTHOR
