I'm having some problems with disks. Probably because I still don't
understand enough of how BSD manage them:
1. I was going to install -current on a USB flash drive. I did the
install media using install59.fs and booted. I scape from installer to
shell because I wanted to wipe the drive using dd(1) and to create a
RAID partition (for FDE). I could not find the disk on /dev/, however.
The system print on screen that the disk is located at "sd5" interface
("dmesg | grep sd" confirm this), but I cound not find it using "disklabel
/dev/sd5". The only interfaces there was sd0 and wd0, none was my disk.
How can I find it? The ./install script can find the sd5 normally, but I
can't find it manually.
2. I gave up of the FDE idea temporarily and I just did the install
normally. No problem to install, but the speed of the system was too
slow... at the point that it was basically unusable (>4 hours to install
10 packages and ~4 minutes to startx).
The device, a USB flash drive, have about 10MB/s write speed. It's kinda
slow, but I don't think this was the cause of the slowliness. I checked
the signature of the snapshot and the installed sets had no problem with
SHA256 too, so it's not a problem with corrupted snapshot.
3. When procceding to wipe the disk on my desktop (openbsd -current too)
I cound not do this. This time I could find sd5 using disklabel, but:
# dd if=/dev/arandom of=/dev/sd5 bs=4096
/: write failed, filesystem is full
dd: /dev/sd5: No space left on device
The same happen on rsd5. When trying to wipe just one partition:
# dd if=/dev/arandom of=/dev/rsd5c
Operation not permitted
The message show after just some seconds (the disk has 7.2GB) and the
partitions still there, so I know that dd did not work.
I thought it was something to do with my kern.securelevel, but when to
down from 2 -> 1 got the same permission problem:
# sysctl kern.securelevel=1
sysctl: kern.securelevel: Operationg not permitted
