hope this is the right list...
I have a "FreeBSD 6.1-PRERELEASE #0: Tue Mar 21 13:29:33 CET 2006" system
with an Areca Raid6 controller (12 x 400GB) which presents a 4TB disk (da0)
to the system:
da0 at arcmsr0 bus 0 target 7 lun 0
da0: <Areca ARC-1130-VOL#00 R001> Fixed Direct Access SCSI-3 device
da0: 166.666MB/s transfers (83.333MHz, offset 32, 16bit), Tagged Queueing Enabled
da0: 3814695MB (7812495360 512 byte sectors: 255H 63S/T 486305C)
when I newfs and label do work when I install the OS. however, after booting the
system from an usb-stick (da1) and change root-fs to da0 I miss 2TB of storage.
At least I can't tellif it's there or not. "/usr" should be 3.6TB and shows
this:
---------------------------------------------------------------------------
Filesystem Size Used Avail Capacity Mounted on
/dev/da0s1a 989M 55M 855M 6% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/da0s1e 1.9G 26K 1.8G 0% /tmp
/dev/da0s1f 1.6T 1.6G 1.4T 0% /usr
/dev/da0s1d 9.7G 27M 8.9G 0% /var
devfs 1.0K 1.0K 0B 100% /var/named/dev
The label editor from sysinstall shows this:
---------------------------------------------------------------------------
Disk: da0 Partition name: da0s1 Free: 0 blocks (0MB)
Part Mount Size Newfs Part Mount Size Newfs
---- ----- ---- ----- ---- ----- ---- -----
da0s1a / 1024MB UFS2 N
da0s1b swap 2048MB SWAP
da0s1d /var 10240MB UFS2+S N
da0s1e /tmp 2048MB UFS2+S N
da0s1f /usr 1662GB UFS2+S N
Output from sysinstall/FDISK:
---------------------------------------------------------------------------------
Disk name: da0 FDISK Partition Editor
DISK Geometry: 486305 cyls/255 heads/63 sectors = 7812489825 sectors (3814692MB)
Offset Size(ST) End Name PType Desc Subtype Flags
0 63 62 - 12 unused 0
63 3517522466 3517522528 da0s1 8 freebsd 165
3517522529 4294972831 7812495359 - 12 unused 0
So, my question is, how big is my "/usr" slice? 1.6TB or 3.6TB?
Thanks,
Lutz Rabing
