is it possible to specify a size to extend an LVM partition to ? rather
than the amount to increase by?
i.e say I have a 2GB partition and what to extend it to 10GB, I  know I
could use  lvextend --size +8G /dev/vgpool/whatever
but is there a command to increase to a specific amount ?

Cheers

Try:

--size 10G

      -L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
              Extend  or set the logical volume size in units of megabytes.  A
              size suffix of M for megabytes, G  for  gigabytes,  T  for  ter‐
              abytes, P for petabytes or E for exabytes is optional.  With the
              + sign the value is added to the actual size of the logical vol‐
              ume and without it, the value is taken as an absolute one.

Thanks for the responses

As I thought it was an easy one.

(its a shame mailing lists don't have the option to label a thread as
[solved] ....
