Description IBM Bug Proxy 2003-11-03 18:37:21 EST
The following has be reported by IBM LTC:  
LVM support needed for 
Hardware Environment: any

Software Environment: standard RHEL 3 GA install

Steps to Reproduce:
1. install lvm source RPM
2. read source

Actual Results: Source includes a fixed list of block devices which
lvm will
allow for its underlying devices.  There is a patch
which adds and IBM's iSeries driver "viod".  In order to support LVM
on top of
IBM's SDD multipathing driver, we need a similar patch to allow
devices named
"vpath".  A sample patch against LVM 1.0.3 will be attached.

Expected Results: Preferrably LVM would allow any block device instead
of having
a hard coded list of strings that are assumed to be block devices. 
Lacking that
we would like "vpath" to be an allowed string.

Additional Information: We created this patch originally two years ago
and it
works.  Presumably Sistina and the kernel.org kernel would not accept this
patch to support a closed source out-of-kernel driver, so we never
asking for it.  Now that RedHat is supporting LVM, and is including
patches to
support special IBM block devices, we'd like SDD to be included as
well.Created an attachment (id=1975)
Patch LVM to support "vpath" devices.

Simple LVM patch to allow the string "vpath" to represent a valid
block device.Glen/Greg - please submit this to Red Hat immediately.

Tim - this bug and patch should be in LTC Bugzilla.  You did the correct 
thing.  What Bob Johnson at Red Hat requested is that we should enter
this into Red Hat Issue Tracker - which I am sure Mark/Glen would gladly
do so.  Thanks.

Glen/Mark - please submit this to RH Issue Tracker.  Thanks.
