Adding size volume existing in veritas

Today i have request from customer for add size mountpoint in veritas environment, Ok lets begin..

Name Disk Group : serverdg
Name Volume : logging

1. Check free size in disk group serverdg

root # vxassist -g serverdg maxsize
Maximum volume size: 472766464 (230843Mb)

2. Add size 5 Gb as requested by user
root # vxresize -g rb34dg log 5g
UX:vxfs fsadm: ERROR: V-3-23544: sectors must be >= 62914561 as they are currently in use.
VxVM vxresize ERROR V-5-1-7514 Problem running fsadm command for volume log, in diskgroup serverdg
root #
Based on the description on the web Symantec, error V-3-23544 (The vxresize command will produce the V-3-23544 error message when the target size is too small for file space currently in use.) resolution : Adjust the resize command plus '+' sign.

root # vxresize -g rb34dg log +5g
UX:vxfs fsadm: ERROR: V-3-20340: attempt to resize /dev/vx/rdsk/serverdg/logging failed with errno 28
UX:vxfs fsadm: ERROR: V-3-23643: Retry the operation after freeing up some space
VxVM vxresize ERROR V-5-1-7514 Problem running fsadm command for volume log, in diskgroup serverdg
root #

ehm..check size filesystem :
root # df -h | grep log
/dev/vx/dsk/serverdg/logging 30G 30G 0K 100% /productions/var/log

ok..for solving this case, first must be clean up filesystem until below 100% from application customer side..after that execute again a command vxresize.
root # vxresize -g rb34dg log +5g
root #
root # df -h | grep log
/dev/vx/dsk/serverdg/logging 35G 30G 5.3G 85% /productions/var/log
