Re: won't boot after 8.0-RELEASE upgrade
I don't think it's FreeBSD update. I always use CVSup and build world. So I fall into the same hole with no way up. I use gmirror, my device names are full including slice (e.g. /dev/mirror/gm0s1a and it was produced from /dev/ad4s1a some years ago), so I think I'm not using “dangerously dedicated” mode... After the update I'm unable to mount root. Thanks God I have my old (7.2 release) kernel... Since I have some servers to manage I am very interested how should I upgrade to 8.0 Rel? Thanks in advance for all your advices!

Re: won't boot after 8.0-RELEASE upgrade
I had to reformat my drive since I had reached "the point of no return"... So I am also nervous. My first failure was with a-kind-of hardware raid, ar, built with cheap VIA VT6421A controller. After installkernel the system refused to boot and on its display was message "hardware failure, you have to destroy and build the mirror again. You will lose ALL data". Frightening, isn't it. So i tested the disks, found them OK and replaced the controller - newer MB with GEOM mirror. Reformat, of course, occurred and all the data was salvaged from the mirror disk. Now I see the card works. It's something with FreeBSD 8.0. This system was installed with FreeBSD 5.1 about may be 4 years ago and upgraded via cvsup til now. I'm sharing this experience to bring your attention to major advice in the update procedure - to take full backup. I think good RAIDs do not store data on the disks in readable by any adapter with same interface format. My question is: how can I guess the result - "Glory" or "Sorrow" BEFORE starting the update? Otherwise, needless to say, 8.0 works perfectly. I mostly use AMD64 version.

Re: won't boot after 8.0-RELEASE upgrade
I have no problems with the hardware. In fact neither Release notes nor UPDATING says anything about my possible (and actually occured) problems. The only thing is: “dangerously dedicated” mode for the UFS file system is no longer supported. I never supposed that I'm using this mode. I format disks and install with sysinstall without any special tuning for fdisk or disklabel. I prefer standard options to ensure smooth future upgrades. So I'd like to know how to distinguish mode of my current filesystems - is it standard or dangerously dedicated?

Re: won't boot after 8.0-RELEASE upgrade
As I guessed, I am using standard, not DD mode. Despite of this I was unable
to boot, and even more: FreeBSD 8.0 sysinstall did not find any partitions
neither on the (g)mirror, hardware RAID I described above or any individual
disks part of the RAID. I had to use FreeBSD 7.2 livefs to copy my data
after I formatted one of the disks with new 8.0 sysinstall.
I think this makes our problem totally unexplained.
As an example I'll show you my "unable to boot system with gmirror" fstab:
# DeviceMountpoint FStype Options Dump
Pass#
/dev/mirror/gm0s1b noneswapsw 0
0
/dev/mirror/gm0s1a / ufs rw 1
1
/dev/mirror/gm0s1d /usrufs rw 2
2
/dev/mirror/gm0s1e /varufs rw,acls 2
2
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
Something I've noticed: when formatting an entire disk with sysinstall prior
7.0 its partition looks like this:
Offset Size(ST)End Name PType Desc Subtype
Flags
0 63 62- 12 unused0
63 781417602 781417664ad4s1 8freebsd 165
781417665 2990 781420654- 12 unused0
When formatted with later versions of sysinstall it looks like this:
Offset Size(ST)End Name PType Desc Subtype
Flags
0 63 62- 12 unused0
63 625142385 625142447ad4s1 8freebsd 165
I notice that the free part at the end is missing. My "hardware" raid,
described above in this thread, stores its metadata in the beginning of the
disk. Writes in the first sectors result in mirror break and the error I
wrote already. I know all of this because I did a lot of tests to help all
of you to find our problem out.
I have to say that my problems occured with system initially installed with
FreeBSD 5 or 6. One system with single drive installed with 7.2 (second
example) upgraded with no problems.
I hope my tests will help to find out what happens wit our older
"disklabelled" systems.

Re: won't boot after 8.0-RELEASE upgrade
Can someone give me a clue what went wrong in so described upgrade and what
made Kernel 8.0 REL not to see either disklabel nor even partition of my
gmirror? I need some advice prior starting upgrade process of the rest of my
servers. As you see in my previous posts the problem is NOT in DD mode!

Re: Root exploit for FreeBSD
I think democracy is a choice of freedom. Freedom what to use, AND, in such cases - freedom where to work! If you are marketing specialist probably you should NOT touch much of your computer's control gear. If you are an IT specialist or support such treatment is similar to treat you as a cattle. It's only up to you to allow or forbid such treatment. The freedom has it's price, of course. I always choose to pay it. If someone hires me to manage something he should listen to my or my team's advices. Otherwise he spends money for nothing and I earn headache and broken nerves! And as for academic battle: If universities deny to make tests, experiments and cutting edge implementations then who would??? If IT or computing science, or telecommunication departments are treated in such manner probably they should be dismissed for not letting them to damage our future specialists! It's a sin to read just one book, even if it is the Holly Bible! God, forgive me for comparing М$ with the Bible, it's just for conviction ;-)! In fact I won partially such a battle in 2002-2003, and even if I don't work for our University they still relay on FreeBSD for major part of their IT infrastructure.

FreeBSD samba+winbind
Dear Sirs, I am having troubles with IDMapping users from Server 2003 AD to my FreeBSD 8.1 Samba 3.5. Well, most of Samba documentation should be considered outdated, I had total failure with RID backend for IDMap. The only working (so far) for me is the default: tdb. I have set nsswitch.conf, pam.d and so on correctly. And here is my problem: everything works almost fine, wbinfo shows my domain accounts, I am able to set these accounts and groups as owners of files. Commands like ls, chown, id show AD accounts correctly. pw, getent - show only local system accounts. I need Samba only for file sharing with ACLs, no PAM authentication or something more. So, technically, it works but since I can't see ALL accounts with getent I think something is wrong. IDMapped accounts are with uid and gid > 1 I think I am missing something very small and simple, so I hope someone will help me!

Re: FreeBSD samba+winbind
Perhaps I couldn't get any attention with my problem or I couldn't explain it in enough details. As you probably read, IDMapping works OK. It seems that my problem occurs in nsswitch. In my /etc/nsswitch.conf I have: group: files winbind #group_compat: nis hosts: files dns networks: files passwd: files winbind #passwd_compat: nis shells: files services: compat services_compat: nis protocols: files rpc: files wbinfo -u / -g / -i DOMAIN_user works OK. Name service switch works almost OK, since system utilities like id, pw /usershow/, chown, ls resolve domain usernames <-> IDMapped UIDs OK. But getent passwd and getent group return only local (system) users /groups. Any clue how to make this work too?

Re: FreeBSD samba+winbind
Hi! Thanks for your reply! Sorry, but that didn't help. I even tried installing samba 3.4 (also form ports). With the same configuration as Samba 3.5 there was no idmapping at all. I'll try to raise loglevel to see what happens. With Samba 3.5 and loglevel 10 there were no significant errors and I think the problem is with nssd and nss_winbind.so (some specific behavior for getting all users - getent).

changing architecture from i386 to amd64
Hi! I have machine working with i386 version of FreeBSD 7.0 Release (after several source updates from 6.0 during the years). Is it possible to re-build kernel and "world" with another architecture, in my case AMD64? I've tried to build kernel in /sys/amd64/conf, but on "make depend" everything fails. I see it includes paths with .../I386/.. even link machine in compile directory points to .../I386. I hope to be able to "switch" my architecture without re-installing FreeBSD with AMD64. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
