[Linuxha-users] 0.8.6 clbuildapp bugfix and lv_list issues(?)

[Simon Edwards]

Hello Leroy,
	Thanks for the feedback - I'll ensure the extra 'chomp' is added until
a better solution can be found. BTW - 'clbuildapp' is being replaced
soon by what is currently available in _clbuildapp - which (will)
support online resizing of file systems etc.

	The other problem is a little more interesting. I've done some testing
on RHEL4 and not seen the lv_list problem before. 

	Would it be possible for you to email me the output of running the
following commands on both servers:

# vgdisplay -v
# /sbin/cluster/utils/lvmtool --haslvm
# /sbin/cluster/utils/lvmtool --lvmtype
# /sbin/cluster/utils/lvmtool --vglist
# /sbin/cluster/utils/lvmtool --lvlist --vgname X

	[In the final command replace X with the name of the
	 volume group you wish to use as part of the cluster.]

Once I get this output I'll starting looking into it. It almost sounds
as if the volume group isn't activated, or the implicit use of vgscan is
failing.

Regards,
Simon.
