What does the command produces?

dmesg

Open in new window


or
Plus did you try
 resize2fs -f /dev/myVG/myLV 307200

Open in new window



This comes from this link, " Size in superblock is different from the physical size of the partition"

Can you check the volume status:

lvs

Open in new window


Plus make sure......
There is no other indication that the LV or VG is open or in use. The 'df ' command reports no mounted filesystems. Neither 'fuser ' nor 'lsof ' report any open files related to this LV.

Check this link, "Why can’t I remove a Linux logical volume? and Cannot Deactivate LVM Logical volume

To remove an inactive logical volume, use the lvremove command. You must close a logical volume with the umount command before it can be removed. In addition, in a clustered environment you must deactivate a logical volume before it can be removed.

If you are trying to remove a disk from the logical volume.....
either to replace the disk or to use the disk as part of a different volume. In order to remove a disk, you must first move the extents on the LVM physical volume to a different disk or set of disks.
