It's ok, I had to experiment fast with different things. My intention is to rebuild the system up to the next week-end - if I have the time, with overnight buildings, maybe tomorrow or so and I'll come up with the answers you require.

Hi,

I upgraded an 8-STABLE box to r206119 and am now unable to boot
multi-user. I found that it hangs at line 58/59 of
/etc/rc.d/initrandom:

( ps -fauxww; sysctl -a; date; df -ib; dmesg; ps -fauxww ) \
| dd of=/dev/random bs=8k 2>/dev/null

when I run each of these commands by hand, I get only as far as
'sysctl -a', which seems to exit normally but leaves my keyboard
unresponsive (actually acting like I'm leaning on the <enter> key).
more digging reveals 'sysctl dev.uart' to be what triggers it.

this is the entirety of dev.uart from r204154:

dev.uart.0.%desc: 16550 or compatible
dev.uart.0.%driver: uart
dev.uart.0.%location: handle=\_SB_.PCI0.UAR1
dev.uart.0.%pnpinfo: _HID=PNP0501 _UID=1
dev.uart.0.%parent: acpi0
dev.uart.0.wake: 0

seems about the same from r206119.

I've attached boot output from r206119.

Any ideas? any other info I need to provide?

thanks much,
Jeff

Wiping the machine as you suggest is not an option.

This is a new, windows 7 preinstalled machine that came with **NO**
windows 7 install disks.

I'd have like to have known this earlier.., I wasn't set to start until

As I said above, the machine did not come with windows 7 installation
media included.

W Block earlier referred to the sysinstall mbr issue as a "rare bug",
but if you have yourself encountered this bug 6 months ago, then it
would appear to have been broken for a long time.

A search of PRs show;
Mon, 26 Sep 2005 14:37:58 GMT: bin/86600: sysinstall(8): Sysinstall
boot manager screen is misleading

Tue, 26 Feb 2008 09:03:41 -0800 (PST): bin/121124: sysinstall(8):
FreeBSD 6.3 installation deletes MBR partition

Sat, 20 Dec 2008 00:11:51 GMT: bin/129771: sysinstall(8): 7.1 RC1
sysinstalls installs boot0 even when told not to

I've been managing FreeBSD servers for years now, so I guess this type
of issue did slip through my attention gap - even so, going by the
earliest date there, seems like this ball has been dropping for a long
time :-/

Thanks for the suggestions, Masoom.

S Roberts

Thanks. Carp is fine, but I still have to figure out how to synchronize
data on disks or in the database. Usign just carp would leave me with
two separate databases containing only parts of users input. Is there a
soulution similar to drbd+heartbeat on Linux? Geom_gate looks nice, but
I have no idea if it has been used in a production enviroment.

All best,

Ah, you're right, it does. Could someone please take a look at that
PR then? Looks like it was submitted in January but hasn't been

Just a status update:

PNG and cURL are in, and png fall-outs are believed to be fixed.

Xorg update has gone through an -exp run on Pointy and our xorg team is
working on fixing the approx. 60 ports with problems.

I will begin -exp runs for Gnome and KDE updates tonight or tomorrow
morning.

Packages status:
- i386:
- 6 after png and curl
- 7 after png and curl
- an 8 incremental build is in progress and should be shortly finished
- 9 pacakges are from middle March
- amd64:
- 6 packages are post png and curl
- 7 build is in progress and will be finished tomorrow
- 8 last build was done in the middle of the png update/fixes; we
won't run an other before Xorg, KDE and Gnome go in (for lack of
resources).
- 9 build in progress (with sources that are believed to fix the zlib
problem).

In other words, if you wish to update without waiting for Xorg, Gnome
and KDE now it's a good moment.

HTH,

The manpage for ldd(1) gives a nice example of finding binaries, which
link against a given library, see

http://www.freebsd.org/cgi/man.cgi?query=ldd&apropos=0&sektion=0&manpath=FreeBSD+8.0-RELEASE&format=html

The example looks as follows:

Unfortunately this example does not work for me. Is seems that the part
with xargs does not output anything and so is the showstopper (?)

It would be nice if someone could give me some advice what is wrong here.

1. The file(1) usage looks incorrect (I get a lot of messages like the
following):

Usage: file [-bcikLhnNrsvz0] [-e test] [-f namefile] [-F separator]
[-m magicfiles] file...
file -C -m magicfiles
Try `file --help' for more information.

2. It's no longer libc.so.6 for many versions of FreeBSD; it can
potentially be libc.so.7...

I use it for production - it works nicely, but you wont get automatic
failover that way.

Ion-Mihai,

Does this fix the following issue?

I have installed FreeBSD 8.0 and updated it to current p2

I try to use konqueror and I get

There was an error loading the module About-Page for Konqueror.
The diagnostics is:
Cannot load library /usr/local/kde4/lib/kde4/konq_aboutpage.so:
(Shared object "libjpeg.so.10" not found, required by "libkhtml.so.7")

Other programs like kile and k3b don't work because of the same
message or others. I did not know about this, otherwise I would not
have tried to install these programs in the first place, till the
coast was clear :(

Thanks though, I saw the message a little bit late :(

Regards,

Antonio

Nope. You need to update all of jpeg. See UPDATING for more
details (but substitute this for the portmaster directions: "
portmaster -r 'jpeg-*' ".

Just to use exact words, fault toulerancy is not possible with any
FreeBSD/Linux O.S.
F.T. means outage can occur in every moment, but all current operation
will be always completed by other equipments; so there will not be
interrupted/lost operations.

The most you can have is HA (High Availability), that means operations
currently executed on servers which have outage are interrupted, but new
operations will be completed as they will be executed on other equipments.

Carp is fine for HA is you have always both db and file storage always
available.
For DB you can use MySQL replica, cross-replicating local MySQL data
among all servers. Each server will keep its own copy, always up to
date with other servers.
This will make all DB data always available, except data recorded in the
last milliseconds.

About file storage, you must have an external reliable NFS server.

Hmm. Thanks for the tip. Which *NIX os can be used to build an FT
solution then? Solaris? AIX? HP-UX?

So, to be redundant one should run 2 x web servers + 2 x storage +2 x
mysql. Sounds like fun, but also like a lot of work. So how do the web
hosting prividers manage to use FreeBSD for theirs solution?
I am curious do they have a cluster/reudndant solution for every part of
the system, or they just accept thet something will fail at some time.

mjb

For a FT solution you need usually an hardware solution, very expensive.
Server must have all doubled, with custom chips for checking if parts
are working (and which part is broken, which may not be easy to understand).

VMware claims to have a software fault toulerant solution, syncronizing
two servers in real-time, but I don't know the efficiency.

The most ISP use HA solutions, which are ok for the most of WEB/e-mail
operations.

Operations are not available for a few milliseconds/seconds, depending
on the architecture you use.

Just to complete, drbd+heartbeat are NOT FT. They are HA. When the
master server goes down, backup server must acknowledge the new status,
then mount the replicated disk (think to disk check!), then start
services working on that disk. So this solution needs a lot of
seconds, probably minutes to work.

With a good carp architecture, you just need milliseconds.

You're asking a question that has not easy or compete answer. Fault
tolerant at what level? Do you want to guarantee that _every_ DB
operation competes? What about random file reads or writes? Do you
want to guarantee that two identical operations with the same data
will produce the same result? (That's _not_ the same as the previous
questions...)

So first you have to define your workload, then define what errors you
must avoid or allow, and then define how to deal with failures,
errors, etc.

Then you can start talking about High Availability vs. level of Fault
tolerance, vs. ....

Let's say i need to run a few php/sql based web sites and I would like
to maintain uptime of about 99,99% per month. No matter how good the
hardware - it will always fail at some time. My goal is to build a
system, that can maintain that uptime.

From what You say I need some level of HA system, to maintain the
required uptime.

So, as I've said earlier (correct me, if I'm wrong) - the setup could
look something like that:

- 2 web servers with carp
- 2 storage servers with on-line sync mechanism running
- 2 mysql servers with on-line database replication

(i'm skiping power and network issues at the moment).

Few people have told me about a setup with linux, drbd and heartbeat
which offers them some level of HA. Has anyone tried anything similar on
FreeBSD?

Each HA implementation is different, you still really haven't provided
enough details eg are servers running off same switch, or are you going to
have latency issues(DRBD and ggate both dislike latency). DB replication
doesn't necessarily need to be done via block level replication. Generally
speaking, you'll make your storage backend HA first, then build other
services off that like iscsi or nfs. There is no single answer to this
because there are so many needs and ways to address them. and yes,
sysutils/heartbeat works with *BSD and they are in use. There are also
other options like

You should wait with this until after the KDE update though if
you donâ€™t want to compile KDE twice.

There is a concept : Self-stabilization .

There will be a ring of computers working simultaneously . If any one of
them fails , others will continue to handle tasks requested from those
systems . Such a ring may utilize load-balancing to distribute work load to
currently working computers .

Actually , FreeBSD itself is an operating system : It manages single

language among others is

Hello!

I just rebuilt my system from 7.2-stable to 7.3. The first thing to fail
upon restart was the PostgreSQL-server. But there are other failures --
for example, webmin is unreachable at its usual https://localhost:10000/

ktrace-ing postgres reveals:

19875 postgres CALL bind(0x3,0x8015190f0,0x10)
19875 postgres STRU struct sockaddr { AF_INET, 127.0.0.1:5432 }
19875 postgres RET bind -1 errno 49 Can't assign requested address
19875 postgres CALL socket(PF_LOCAL,SOCK_DGRAM,0)
19875 postgres RET socket 4

I rebuilt postgress server anew, just in case, but it is still
failing... Changing the listen_addresses from 'localhost' to
'my.lan.ip.add' allows the server to start-up, but now I need to change
the configuration of the local applications...

Similarly, 'ssh localhost' no longer works, although `ssh my.lan.ip.add'
works...

The only unusual thing about my system is that I build with
`NO_INET6=yes'. But it all worked with the kernel from a month ago...
The ::1-definition in /etc/hosts is now commented-out, but that didn't
help any...

Please, advise. Thanks!

Check ifconfig -a and make sure lo0 appears / has a correct IP address,
and the interface is up.

Also, if the machine has firewall rules, make sure they're written so
that lo0 is excluded from the list (in pf.conf, 'set skip on lo0' does
the trick).

You are right, it is not up:

lo0: flags=8008<LOOPBACK,MULTICAST> metric 0 mtu 16384

Manually running `ifconfig lo0 127.0.0.1' fixed the problem for the time
being...

But why? What changed so significantly in the last few month, that lo0
broke, of all things? :-)

Thanks!

It hasn't broken on any of the systems I maintain, including my own two
home servers. If this problem was common/widespread, there'd be a lot
more reports of it coming in.

There is likely something else going on in your rc.conf or configuration
setup (possibly you botched a mergemaster merge?) which is causing the
problem.

I disagree with some of the wording. Specifically, lines 100-102 of
usr.sbin/sade/menus.c

"If you will only have FreeBSD on the machine the boot manager is not
needed and it slows down the boot while offering you the choice of
which operating system to boot."

^^ not 100% true, as the boot manager also provides the option of PXE
booting. This statement seems excessively wordy and unnecessary.

Also, should this be broken up into two patches? One for the change in
sade, the other for sysinstall? I'm not picky about this, but you are
fixing two issues in two separate programs.
