vxresize may fail when you shrink a file system with the \"blocks are currently in use\" error (3762935)
The vxresize shrink operation may fail when active I/Os are in progress on the file system which is being shrunk to a size closer to its current usage. You see a message similar to the following example:
UX:vxfs fsadm: ERROR: V-3-20343: cannot shrink /dev/vx/rdsk/dg1/vol1 -
blocks are currently in use. VxVM vxresize ERROR V-5-1-7514 Problem
running fsadm command for volume vol1, in diskgroup dg1
Workaround: Re-run the shrink operation after stopping the I/Os.
