The problem is that sector count variable in partition table and bsdlabel on i386 are 32bit - so maximum size of one partition/label are 2 TB. But You can create (with command line fdisk from FreeBSD 5.x) more partitions on big disk and this works (I have two 2 TB partitions on 4 TB array): # df Filesystem Size Used Avail Capacity Mounted on /dev/da1s1d 1.9T 1.7T 64G 96% /matrix1 /dev/da1s2d 1.9T 1.8T -59G 103% /matrix2 /dev/da0s1d 1.9T 1.7T 57G 97% /matrix3 /dev/da0s2d 1.9T 1.7T 95G 95% /matrix4 The second solution is using WHOLE disk (without partitioning and disklabeling) for one file system: newfs -U /dev/da0 mount /dev/da0 /mnt But in this situation the system must start from other small disk... -- best regards steve at home.pl
