Add a volume (Normal UFS mounted filesystem)

Remove a volume
# dmesg Check for recent errors # df -k Check the volume is not mounted # vxprint <vol> # vxassist -g datadg maxsize Check current space in datadg # vxvol -g datadg stop <vol> Stop the volume # vxprint <vol> Check volume is stopped # vxedit -g datadg -rf rm <vol> Remove volume # vxassist -g datadg maxsize Check for new space # dmesg Check for any errors
Increase a volume
# dmesg Check for recent errors # df -k /oracle_backups Check current size of filesystem, 5Gb # vxassist -g datadg maxsize Check available space in datadg # vxprint orabck_filvp Check current size LENGTH=10240000 # vxassist -g datadg -U fsgen growby orabck_filvp 10g Increase vol by 10gb # vxprint orabck_filvp Check new size LENGTH=31211520 # /usr/lib/fs/ufs/mkfs -F ufs -M /oracle_backups /dev/vx/rdsk/datadg/orabck_filvp 31211520 # df -k /oracle_backups Check new size of filesystem, should by 15Gb # vxprint orabck_filvp Check volume is ENABLED # dmesg Check for recent errors
