RHEL 5.0 manual typo in lvextend of a striped volume
Last modified: 2009-04-16 19:01:56 EDT
In the RHEL5 cluster LVM manual, on page 45 of the PDF version, when explaining
how to extend a striped LV when not enough space exists to extend using the same
stripe setup, it mentions to use -iL. From what I can find, this is invalid -
you would instead use -i1.
volume, but you can override those parameters. The following example extends the
striped logical volume to use the remaining free space after the initial
lvextend command fails.
# lvextend vg/stripe1 -L 406G
Using stripesize of last segment 64.00 KB
Extending logical volume stripe1 to 406.00 GB
Insufficient suitable allocatable extents for logical volume stripe1: 34480
# lvextend -iL -l+100%FREE vg/stripe1
Moving all RHCS ver 5 bugs to RHEL 5 so we can remove RHCS v5 which never existed.
I have fixed the lvextend example so that it specifies the actual number 1
(indicating that the volume should be extended on to one stripe, which is
pragmatically not really a stripe...) instead of the typo-ed letter L. Good catch.
I have requested that the updated version of the document be pushed out to the
docs web page, with RT 26340.
The RHEL 5 version of the LVM manual on the docs web page has been updated with a version of the document that corrects this typo.
