Hello, I am running a FreeBSD 8.2-RELEASE-p6 GENERIC (amd64) home media server I wanted to find a way to add multiple disks to a single volume without using raid because I am not too fussy about the data but I dont want one disk failing to cause me to loose all my data. I found gconcat and it seemed to be the exact application I was looking for. I first created a volume with a single drive (1.5 TB) so that I could migrate all my data across. (I was using zfs but as stated I dont need/want raid). # gconcat label -v data /dev/ad4 # newfs /dev/concat/data # mount /dev/concat/data /mnt Everything seemed fine and I was able to migrate my data across with no problems. I then tried to add two more drives (1 TB each) using the following commands: # umount /dev/concat/data # gconcat label data /dev/ad4 /dev/ad5 /dev/ad6 Once again everything looked fine and when I execute gconcat list I can see the drives are added and the space allocation is correct. # gconcat list Geom name: data State: UP Status: Total=3, Online=3 Type: AUTOMATIC ID: 1745188505 Providers: 1. Name: concat/data Mediasize: 3500711680512 (3.2T) Sectorsize: 512 Mode: r0w0e0 Consumers: 1. Name: ad4 Mediasize: 1500301910016 (1.4T) Sectorsize: 512 Mode: r0w0e0 Start: 0 End: 1500301909504 2.
