Re: add a new partition in USB ( clone )
Hi, all . this is a method to make clone USB larger size than original . 1) use linux (because openbsd fdisk is hard to use) by fdisk , make /dev/sdb4 Id:a6 2)then use 'openbsd5.5 install CD disk' for installboot on installing OpenBSD use OpenBSD area - 1) mount point / (because original USB has a and b only) install bsd, bsd.rd, base55 only 3)then openbsd runninng machine, # mkdir /mnt0 # mkdir /mnt1 # mount /dev/sd0a /mnt0 - / partition # mount /dev/sd1a /mnt - / partition # (cd /mnt0; tar cvpf - .)|(cd /mnt1 ; tar xpf -) #umount /mnt0 = cannot #umount /mnt1 = cannot so halt openbsd machine , 4)then goto linux machine fdisk /dev/sdb make bootable flag on sdb4 ( if 1) has this priicedure , this may be needless ) --- this method is perhaps effective to smaller USB clone , or USB to Hard disk clone and so so . --- tuyosi
add a new partition in USB
Hi all .
i have 32GB USB memory . and this is clone of ' 2GB live USB '.
so i want to extend 'this clone 2GB' to about 8GB .
in order to this , i want to make ' partion d ' in 32GB USB .
so i do next steps .
# fdisk -e sd0
fdisk: 1 edit 0
Partition id ('0' to disable) [0 - FF]: [0] (? for help) 1
fdisk: 1 setpid 0
Partition id ('0' to disable) [0 - FF]: [1] (? for help) A6
fdisk:*1 w
fdisk: MBR contains more than one OpenBSD partition! --- attention
Write MBR anyway? [n] y
now
# fdisk -e sd0
fdisk: 1 p

*3: A6 0 1 2 -242 254 63 [ 64: 3903731 ] OpenBSD
i want to make partition d in
' #0 243 0 1 - 1000 0 1 OpenBSD ' .

i try
# disklabel -E sd0
p

#size offset fstype [fsize bsize cpg]
c: 617021440 unused
this is strange to me because i already had a
in ' #3: A6 0 1 2 -242 254 63 OpenBSD '.
but thre is no ' partition a '
what should i do next to make ' partion d' in 32GB USB ?
and where is ' partition a ' ?

You need to read http://www.openbsd.org/faq/faq14.html and read what is actually there, not what you think is there. You can only have one OpenBSD fdisk partition...and the answers to your questions are in the above link. Nick.
Re: add a new partition in USB
Hi, all. till iread Nick's reply , i make clone 32GB USB from 2GB USB by dd. and am making new partition on 32G USB . but fail ,fail , from now i change strategy . erase 32GB USB completely , and make a partition ,and copy files from 2GB to 32GB . 2G USB is recognized as sd0 by amd64 openbsd machine. 32G USB is sd1 . disklabel -E sd1 d * A and erese k etc . (i can't make big size a partition directly . some technique is needed ) result is next . p OpenBSD area: 0-61702144; size: 61702144; free: 51692144 #size offset fstype [fsize bsize cpg] a: 1000 39486816 4.2BSD 2048 163841 b:10swap c: 617021440 unused q # mkdir /mnt0 # mkdir /mnt1 # newfs sd1a # mount /dev/sd0a /mnt0 # mount /dev/sd1a /mnt1 # cp -r /mnt0/* /mnt1 or (cd /mnt0; tar cvpf - .)|(cd /mnt1 ; tar xpf -) the latter may be much faster . regretably , # cd /usr/mdec; ./installboot /mnt1/boot biosboot sd1 ksh: ./installboot: not found FAIL # /usr/sbin/installboot /mnt1/boot /usr/mdec/biosboot sd1 installboot: disklabel: /mnt1/boot: Inappropriate ioctl for device also FAIL . pehaps umount /mnt0 umount /mnt1 continue . what is ' appropriate ioctl for device ' ? --- tuyosi
