Hello Måns
I now realize how I created this problem, I just don't know how to fix
it.
I mistakingly added /dev/sba as the physical volume to a volume group
that contained /dev/sba1, the one partition on sba. These are
essentially one in the same. So when I executed the lvextend command
device-mapper had an error. I'm honestly surprised it did anything,
especially write over the superblock on the filesystem.
Any direction on how I can recover from within LVM? I never was able
to execute the xfs_grow so I'm hoping the data in the filesystem still
exists.
try
xfs_repair -n -o /dev/Volume00/LogVol00
Then remove the -n
(man xfs_repair)
