How to partition magneto-optical disks with sectors of 2048 bytes?
Dear OpenBSD community, I have got some SCSI magneto-optical drive together with a new 2.3GB removable MO disk. My system has configured it as follows: OpenBSD 4.8 (GENERIC.MP) #335: Mon Aug 16 09:09:20 MDT 2010 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP ... sd0 at scsibus0 targ 3 lun 0: FUJITSU, MCJ3230SS, 0010 SCSI2 0/direct removable sd0: 2076MB, 2048 bytes/sec, 1063146 sec total ... (You will find a full dmesg.boot listing attached to this message.) In any case I want to use the whole disk for OpenBSD FFS. I could install some raw filesystem # newfs -N /dev/rsd0c /dev/rsd0c: 2076.5MB in 4252584 sectors of 2048 bytes 11 cylinder groups of 202.47MB, 12958 blocks, 25984 inodes each super-block backups (for fsck -b #) at: 32, 414688, 829344, 1244000, 1658656, 2073312, 2487968, 2902624, 3317280, 3731936, 4146592, but this is not recommended in FAQ (Chapter 14) and also not my intention.
