[Libguestfs] [PATCH 0/3] sparsify: Ignore read-only LVs (RHBZ#1185561).
virt-sparsify shouldn't die if sparsifying a filesystem that contains
read-only LVs.

I thought about trying to make the LV writable temporarily, but I
suspect that if the sysadmin has made the LV read-only, then they
probably did it for a reason, so we shouldn't touch it.
Rich.
