vxresize

hi,

you can see that df -k /symora_tmp ->584288 and vxprint -g genio/-dg|grep genio05->2072576

then vxresize -b -g genio_dg genio05 512m.

vxprint -g genio-dg|grep genio05->1048576 but df -k /symora_tmp->524288.i expected the value to be half of this.

why this?

  • VxVM command such as "vxprint" reports the size of objects such as volume/plex/subdisk in terms of number of blocks and usually block size is 512 bytes. Which means 1Kbytes = 2 blocks.

    In the o/p of second image 1048576 blocks = 1048576 / 2 = 524288 KBytes => 524288 / 1024 => 512 MBytes

    In "dh" you have explicitly mentioned -k and hence it printed o/p in that format.

    Vxprint also has human-readable print option such which can show o/p in similar format.

    vxprint -uh will convert the blocks in near by unit of KB/GB/TB and u can control is you want o/p in specific unit e.g

    -ug => Giga bytes

    -uk => Kilo Bytes

    -ut => terra bytes

     

    vxprint -v -uh
