vxresize - instead of ufs, I have given vxfs

Hi

Not seen that done before, but it appears to have actually used the UFS grow operation, even though you used the vxfs switch. I ran a trivial similar test and it also appears to have grown the FS. I also ran a truss to look for the the mkfs commands(notice its using ufs paths):

boo# vxassist -g testdg make tony1 100m
boo# newfs /dev/vx/rdsk/testdg/tony1
boo# mount -Fufs /dev/vx/dsk/testdg/tony1 /tony1
boo# df -k /tony1
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/vx/dsk/testdg/tony1
                       95551    1041   84955     2%    /tony1

boo# truss -failed -o /tmp/truss vxresize -g testdg -Fvxfs -x tony1 +100m
boo# df -k /tony1

boo# grep mkfs /tmp/truss

26312/1:         0.8881 stat64("/usr/lib/fs/ufs/mkfs", 0xFFBFF8F0)      = 0

As a precaution you may want to take a backup of the file system
