After second sysinstall attempt I created another 2TB slice and now at least I can use whole space. Not so good but it works. Second attempt: Now I reserved 20GB for "boot volume" from 3Ware 9650SE controller and looks like it ...oops...did it again....deem. # df -H Filesystem Size Used Avail Capacity Mounted on /dev/da0s1a 2.1G 146M 1.8G 8% / devfs 1.0k 1.0k 0B 100% /dev /dev/da1s1d 1.2T 4.1k 1.1T 0% /data /dev/da0s1d 3.1G 12k 2.9G 0% /tmp /dev/da0s1f 8.3G 450M 7.2G 6% /usr /dev/da0s1e 4.2G 281k 3.8G 0% /var NOTE: during sysinstall partition creatin it showd me 3.2TB of /data... # dmesg da0 at twa0 bus 0 target 0 lun 0 da0: <AMCC 9650SE-8LP DISK 4.06> Fixed Direct Access SCSI-5 device da0: 100.000MB/s transfers da0: 20479MB (41943039 512 byte sectors: 255H 63S/T 2610C) cd0 at umass-sim0 bus 0 target 0 lun 0 cd0: <ATAPI DVD A DH20A3P XP5Z> Removable CD-ROM SCSI-0 device cd0: 40.000MB/s transfers cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed da1 at twa0 bus 0 target 0 lun 1 da1: <AMCC 9650SE-8LP DISK 4.06> Fixed Direct Access SCSI-5 device da1: 100.000MB/s transfers da1: 3317309MB (6793848833 512 byte sectors: 255H 63S/T 422897C)
