I'm doing a little testing and I hit a strange point. Here is a zvol (clone)

pool1/volclone      type             volume                 -
pool1/volclone      origin           pool1/v...@diff1       -
pool1/volclone      reservation      none                   default
pool1/volclone      volsize          191G                   -
pool1/volclone      volblocksize     8K                     -

The zvol has UFS on it. It has always been 191G and we've never attempted to resize it. However, if I just try to grow it, it gives me an error:

-bash-3.00# growfs /dev/zvol/rdsk/pool1/volclone 400555998 sectors < current size of 400556032 sectors

Is the zvol is somehow smaller than it was originally? How/why?

It fsck ok, so UFS doesn't seem to notice.

This is solaris 10 u6 currently, the machine (and zpool) have gone through a few update releases since creation.

Thanks for any input,
-Brian
