Hi all- 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 RAID volume: # 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 might proceed? Thanks in advance for any and all help, Darren David
