stripping

[Jeff Hagstrom]

How do I find out if stripping is turn on in the HP box? How do I find out what disks my volume groups are on?

Hello,

Use the lvdisplay command to see if your logical volumes are striped, and 'vgdisplay -v' to see which disks are in a volume group. The man pages on both these commands should help.

lvdisplay -v /dev/vg*/l*|grep -e "LV Name" -e "Stripes" | more

If any of the LV's have a number other than 0, then they are striped (and the number represents the number of stripes).

Hi Jeff,

How do I find out if stripping is turn on in the HP box? How do I find out what disks my volume groups are on?

1. To find out if striping, issue the following command :

#lvdisplay -v /dev/vg??/lv* ? more

and see the line starting with "Stripes" :
Value 0 = No
Value 1 = YES

2. To find out what disks in your volume group, issue the following command :

#vgdisplay -v vg?? ? more

go to the end till :

----- Physical volumes -----

after you will find all your disks in that volume group.

Hi Jeff

The simple command is

lvdisplay < /dev/vgXX/lvolXX> | grep Stripes

if the value is zero it is not striped otherwise the no say the volumes the filesystem is striped across.
