The adress you have found is the address of a mailing list. sistina has
created the lvm system. Now this have moved to redhat et the mailing
list adress is linux-lvm at redhat.com
About your problem, when you want to extend a filsystem which is on a
logical volume, you need to:
- expand the logical volume first
- then expand the filesystem itself
lxextend command only extend the logical volume, not the filesystem.
For instance, in case of an xfs filesystem, the command to use is
xfs_growfs.
There are command for most of the filesystems. Some have resctrictions
: xfs cannot be schrink and must be mounted before expanded.
