+
+When running pvmove, we need to decide whether pvmove has to be doing

+
+Whenever LV that requires exlusive activation is present, it makes
+pvmove exlusive. But when there is already activate i.e. linear LV
+in exclusive mode it also needs to switch pvmove into 'exlusively
+activating' pvmove.

+Subject: [PATCH 6/6] thin: activate layer pool aas read-only LV
+
+When lvm2 is activating layered pool LV (to basically keep pool opened,
+the other function used to be 'locking' be in sync with DM table)
+use this LV in read-only mode - this prevents 'write' access into
+data volume content of thin-pool.
+
+Note: since EMPTY/unused thin-pool is created as 'public LV' for generic
+use by any user who i.e. wish to maintain thin-pool and thins himself.
+At this moment, thin-pool appears as writable LV. As soon as the 1st.
+thinLV is created, layer volume will appear is 'read-only' LV from this moment.

+Subject: [PATCH 2/6] vgcreate/vgextend: restrict PVs with mixed block sizes
+
+Avoid having PVs with different logical block sizes in the same VG.
+This prevents LVs from having mixed block sizes, which can produce
+file system errors.
+
+The new config setting devices/allow_mixed_block_sizes (default 0)
+can be changed to 1 to return to the unrestricted mode.

+%description
+LVM2 includes all of the support for handling read/write operations on
+physical volumes (hard disks, RAID-Systems, magneto optical, etc.,
+multiple devices (MD), see mdadm(8) or even loop devices, see
+losetup(8)), creating volume groups (kind of virtual disks) from one
+or more physical volumes and creating one or more logical volumes
+(kind of logical partitions) in volume groups.
