The problem I am facing happens during installation of OpenBSD 4.2
-release, -stable, or -current as of January 1st (both amd64 and i386).
I can very easily reproduce this issue every time. I've been testing for
the last 48 hours, and can confirm that it never happens on 4.0 or 4.1.
Happens with SATA drives, never with PATA. See the dmesg with SATA at
the bottom (dmesg is for -stable, no custom changes otherwise).
Firstly, while I try to upgrade my 4.1/amd64 box to 4.2/amd64, the
upgrade script tries to fsck /dev/wd0a, but gives me the following:
wd0a: id not found reading fsbn 128 of 128 143 (wd0 bn 8755093022399; cn
547... tn 80 sn 4), retrying
wd0: transfer error, downgrading to Ultra: DMA mode 4
It downgrades down to DMA mode 2, finally gives up as FAILED, and
instructs me to fsck manually (which doesn't work either).
And, disklabel output at this point looks strange:
# size offset fstype [fsize bsize cpg]
a: 4036512 8755093022271 4.2BSD 0 0 256
The expected offset for partition a is of course 63. (disklabel in
4.2/i386 does the same too.)
Just to confirm my observations, I managed to replace disklabel binary
of 4.2 installation (in /sbin of rd0a) with the one from 4.1, and it
does not have this issue.
4.2 disklabel behaves the same in install mode too. I mean, if I give up
on upgrade (which is every time) and choose to install instead, after I
drop to disklabel editor, and print the existing partitions, I see
exactly the same huge number as the offset. But the difference is that
if I continue with install without changing anything in disklabel
editor, newfs cannot format the partition, and gives me the same "id not
found... downgrading ... DMA mode to..." errors as above, and finally
gives up.
Therefore, the only way to install 4.2 (on my system with SATA HD
already partitioned) is to zero out the partition table and recreate all
the partitions in disklabel editor, and everything works fine
thereafter.
If this issue did happen with 4.0 and 4.1 too, then I could blame my
hardware (perhaps nvidia chipset). But upgrading from 4.0 to 4.1 is
fine. Up/downgrading from 4.2 to again 4.2 works fine too. And,
otherwise this system has been running fine for more than a year now.
Also, trying to *fake* downgrade from 4.2 to 4.1 fails during fsck (did
not really downgrade, just wanted to test disklabel, fsck, mount, and
newfs of 4.1). But downgrade from 4.2 to 4.0 seems to fsck fine.
I have tried with many different partitioning, enabled/disabled IDE and
SATA ports in bios, and used install42.iso (-release), cd42.iso
(snapshot), etc.
disklabel output after first boot seems fine, i.e. the issue I am
reporting is only during installation of 4.2.
I have seen that there are major changes to disklabel (and related
tools) since June. Could this issue be related with those?
I would appreciate any help. I can file a bug report if this is really a
bug.
(I myself have tried a patch before submitting this post, namely, a
typecast to u_int64_t for the starting_sector in find_bounds() in
editor.c, but it did not fix the disklabel offset. Lines 1649 and 1650
in -stable.)
