Then, I tried to grow filesystem size using 'growfs' command. However, growfs does not work. It looks like growfs can not get correct number of sectors. The result of simple test is as follows. 1. making test volume I made single disk volume, device name is /dev/da2, size is 465 GB. oxygen# tw_cli /c0/u2 show Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ------------------------------------------------------------------------ u2 SINGLE OK - - p5 - 465.651 oxygen# dmesg | grep da2 da2 at twa0 bus 0 target 2 lun 0 da2: <AMCC 9550SXU-8L DISK 3.08> Fixed Direct Access SCSI-5 device da2: 100.000MB/s transfers da2: 476827MB (976541696 512 byte sectors: 255H 63S/T 60786C) 2. I confirmed that this volume is usable with no problem. oxygen# newfs -b 65536 /dev/da2 increasing fragment size from 2048 to block size / 8 (8192) /dev/da2: 476827.0MB (976541696 sectors) block size 65536, fragment size 8192 using 249 cylinder groups of 1922.00MB, 30752 blks, 246016 inodes. super-block backups (for fsck -b #) at: 256, 3936512, 7872768, 11809024, 15745280, 19681536, 23617792, 27554048, 31490304, . . . oxygen# mount /dev/da2 /mnt/test oxygen# df -h /mnt/test Filesystem Size Used Avail Capacity Mounted on /dev/da2 451G 16K 415G 0% /mnt/test 3. labeling to the disk. oxygen# fdisk -BI /dev/da2 ******* Working on device /dev/da2 ******* fdisk: Geom not found: "da2" oxygen# fdisk /dev/da2 ******* Working on device /dev/da2 ******* parameters extracted from in-core disklabel are: cylinders=60786 heads=255 sectors/track=63 (16065 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=60786 heads=255 sectors/track=63 (16065 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 976527027 (476819 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 369/ head 254/ sector 63 The data for partition 2 is: <UNUSED> The data for partition 3 is: <UNUSED> The data for partition 4 is: <UNUSED> oxygen# bsdlabel -w /dev/da2 oxygen# bsdlabel /dev/da2 # /dev/da2: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 976541680 16 unused 0 0 c: 976541696 0 unused 0 0 # "raw" part, don't edit 4. making the filesystem.
