+++ This bug was initially created as a clone of Bug #349911 +++ 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. <context follows> volume, but you can override those parameters. The following example extends the existing 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 more required # lvextend -iL -l+100%FREE vg/stripe1 -- Additional comment from nstraz on 2007-12-13 12:45 EST -- Moving all RHCS ver 5 bugs to RHEL 5 so we can remove RHCS v5 which never existed. -- Additional comment from slevine on 2008-07-31 12:36 EST -- 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.
With the release of RHEL 4.8, the LVM document is now correct.
