Hello,
I recently acquired a 3TB USB disk that attaches as a sd0 disk. disklabel
reports that it has 4k sectors. I can write a disklabel on the disk, but newfs
can not create a fs.
(parts of the disk label)
bytes/sector: 4096
sectors/track: 32
tracks/cylinder: 64
sectors/cylinder: 2048
cylinders: 357698
total sectors: 732566642
d: 732566642 0 unused 0 0 # (Cyl. 0 -
357698*)
e: 50000 63 4.2BSD 1024 8192 0 # (Cyl. 0*- 24*)
f: 732516579 50063 4.2BSD 4096 32768 0 # (Cyl. 24*- 357698*)
bash-4.1# newfs -S 4096 /dev/rsd0e
/dev/rsd0e: 195.3MB (50000 sectors) block size 32768, fragment size 4096
using 4 cylinder groups of 48.84MB, 1563 blks, 3072 inodes.
rdfs: read error for sector 1: Invalid argument
bash-4.1# newfs -S 4096 /dev/rsd0f
/dev/rsd0f: 2861392.9MB (732516579 sectors) block size 32768, fragment size 4096
using 3860 cylinder groups of 741.31MB, 23722 blks, 47104 inodes.
wtfs: write error for sector 732516578: Invalid argument
I'm running 5.1/i386.
(The e: above was just to try a small size.)
Is there support for 4K sectors in 5.1? I've read that other people have
successfully created file systems on 4k sector devices.
So, what am I doing wrong?
