** resend gmane gateway either didn't work or was very slow. Apologies
for the duplication if it ever shows up
system: Ubuntu 5.10
first mistake was trying to use Ubuntus installer to set up LVM and raid.
second mistake was trying to use EVMS to set up LVM and raid.
resorting to what works (mdadm and LVM2 commands)I found myself getting
this error message with every LVM command
Incorrect metadata area header checksum
I deleted the first five or 10 MB of each disk in the raid set but it
persists. Everything seems to operate, storage has been allocated,
filesystems have been built, everything is detected on reboo and I have
even resized one of the logical volumes and expanded the disk.
however, what I have read says that this warning message about incorrect
metadata is something to be concerned about. My question is, how do I fix?
second, this is probably a "RTFWP" question but how do you determine the
free space on a physical volume. For example, if I have two logical
volumes created and I want to know how much space is left on the
physical? (apologies if I got the vocabulary wrong)
