I need some help figuring out how to expand the existing partition on my
RAID volume to take advantage of a new disk I just added -- without
newfs'ing the volume and starting from scratch.
I added a 4th 750GB disk to my existing 1.5TB 3ware RAID5 volume, in an
attempt to bring my total capacity up to ~2.25TB (4x750GB RAID5). I
successfully used the 3ware 'tw-cli' utility to perform "Online Capacity
Expansion." The controller migrated the existing data across all 4
disks, and it now reports a total volume capacity of 2095.44GB.
Now, I'm not quite sure how to get FreeBSD to recognize the extra space.
I know that in order to use growfs, I first have to use disklabel to
increase the partition size. However, disklabel doesn't like this big
# disklabel /dev/da0
disklabel: disks with more than 2^32-1 sectors are not supported
and the existing partition doesn't seem to have a label:
# disklabel /dev/da0s1
disklabel: /dev/da0s1: no valid label found
I'm unsure how to proceed here. CAn anyone shed some light as to how I
Thanks in advance for any and all help,
