circular link schroot 1.4.19-1

[Mihamina Rakotomandimby]

Hi all,

This morning, I upgraded my system and:

  apt-get upgrade
  [...]
  Setting up schroot (1.4.19-1+squeeze1) ...
  dpkg: warning: schroot: config file '/etc/schroot/default/nssdatabases' is a

No results.

Has someone any similar warnings?

This makes no sense to me. Using static IPs doesn't involve your router. Use 
them or not, it won't care (or know).

NFSv4 is a giant pain in the keister, not worth the headaches. The
NFSv4 access published from an actual Linux or other NFSv4 capable
service can be published, it can be passed along via Samba to CIFS
clients, but the CIFS clients cannot *see* or manipulate the NFSv4
permissions due to incompatibilities between thee two ownership
models, and due to the Samba code for this being "spaghetti code".
(http://samba.2283325.n4.nabble.com/viewing-if-not-editing-NFSv4-ACL-s-from-Samba-shares-td2417666.html).

Overall, NFSv4 has proven itself destabilizing and useless in small
and large environments. It takes a significant investment in complex
infrastructure, and the security benefits have proven to be illusory
in the face of clients who *insist* on making their home directories
publicly accessible, clients who use password free SSH keys, or
clients who store passwords in source controlled software with no
access control. (I've run into all of these in environments that spent
useless years pursuing the "security" of NFSv4 and ignoring gaping
holes in infrastructure security.)

The problem isn't getting it up and running. It's getting people to
actually use it. It's sensitive to time drift on the servers and
clients, and getting people configured with NTP correctly is only a
tiny part of the battle. For a hundred accounts? I can see it. For
half a dozen people in a small office? Unlikely to be worth it.

>From another part of the thread: I've used openAFS, including porting
it and Kerberos to SunOS way the heck back in antiquity. (Whose bright
flipping idea was it to make Kerberos require a fully qualified
hostname as the first entry in /etc/hosts for your IP address rather
than the short name, to make compilation fail if it wasn't, and to set
a timestamp so that the compilation had to *start over from the
beginning? Actually, I think I know, and I've gotten private vengeance
for this.)

Debian's leading edge packaging and integration testing should make
them both vastly easier. You're stuck with policy decisions in setup
that can be subtle and awkward.

Most models also support DHCP reservations, to get the IP addresses
set consistently and not have to manually manipulate the network on
your clients.

On both Debian and Ubuntu, I used to be able to run "dpkg-reconfigure
grub-pc", choose md0, sda, and sdb, and grub would be installed on all
three. For a while now (I can't remember for how long), installing to
md0's failed.

What do RV and GAI mean? I've googled both and not foudn anything to
help. "0.90" and "1.2" are mdraid metadata versions. Were these disks
previously in another array and do you now have two types of metada on
them?

Hi Vlada,

are you using NetworkManager ? I've had similar issues and editing 
/etc/NetworkManager/networkmanager.conf to manage the devices solved 
this issue:

Another "solution" is to completely remove NetworkManager and use wicd

problems with Gnome and KDE

[Vladimir Kerka]

Hi,
I really need help with two problems:
1. minor problem: whenever I start Gnome, there is message like this:
"Jun  5 22:55:47 dunadan gnome-session[4527]: WARNING: Application 
'nautilus.desktop' failed to register before timeout"

in the syslog.
I cannot put anything on the desktop and there is no possibility to 
click on it with my mouse (left nor right button)

I hardly tried to find solution on the web, but without success
2. major problem: I use KDE 4.6.X from Sid, but the session crashes 
immediately after start (this is the reason, I sent the copy to debian-kde).
I tried to rename .kde in the home, no luck. More than that, when I try 
to play KDE origin game (e.g. KBreakOut), when it comes to the end, it 
crashes


Can any of you give me a clue?

Many thanks

Vlada

Yes, if you add the pvmove step that I forgot to mention. Just expect a
(heavy) drop in IO performance as both the new and the old disk are very
busy during the move.

If you also have filesystems on non-LVM devices, you have to take care
of them by other means. If you boot from the disk, don't forget to
grub-install.

Problems installing grub/lilo with RAID1 on /

What is your point in mentionning this requirement? Do you mean that  
the

server should not send packets bigger than 1280 bytes if it fails to
handle properly path MTU discovery ? If so, I fully agree.


My point is that by setting your MTU to 1280, you have done *your*  
part.  At least you can be assured that all your packets will get thru  
without fragmentation, even if the host at the other end -- or some  
intervening router -- is improperly configured.


If the host on the other end sets its MTU to something larger and an  
intervening router doesn't do fragmentation, they (or the admins of  
the router) need to fix that.  An easy recommendation that you can  
make in this case (if the server admin on the other end is clueless  
but willing to help) is for them to set their MTU to 1280 as well.   
That will fix the problem regardless of intervening routers.


Finding a (possible series of) mis-configured intermediate router(s)  
and convincing the respective router-admin(s) to fix their  
configuration is often difficult.  It's easier if you have only one  
person to talk to, the server admin on the other end.





So it makes
sense (if you're going to go to the trouble of setting the MTU in the
first place) to use that number.


Lowering the MTU at the client side does not fix the problem that  
exists

at the server side. It is just a workaround that works for TCP because
it happens that TCP uses the *outgoing* MTU to calculate the  
advertised

*incoming* MSS (how weird when you consider that internet routing is
likely to be asymmetric).


In the particular case in hand -- aptitude/apt-get talking to  
schein.debian.org, that is: the ipv6 avitar of security.debian.org --   
I have observed that setting your own MTU to 1280 is all that's  
necessary.


Enjoy!

you want to take advantage of the additional space.


Hi Jochen,

and this will also work when the operating system is running on this lvm 
? Downtime is no issue because it's my "home cluster" and the resources 
will switch to the other server anyway, so no "real" downtime.


the other problem is - there is no free slot for the new disk, so i 
think I'll stay with dd'ing or something like that. I'll write back if 
it was working or if there were issues with that.


Thanks and best Regards

As you installed GRUB into the MBR, that makes sense.

"Also"? :-?

AFAIK, there can only be one partition marked with the bootable flag -one 
partition per hard disk- so did you removed the bootable flag from "/dev/
sda6" and put it on "/dev/sda2"? 

As root, run "fdisk -l" so we can see what's your current disk layout.

I think the installer did the right thing, maybe your BIOS just had some 
sort of problem/incompatibility for booting from the linux extended 
partition.

Hum, just out of curisosity... fave you tried to boot windows from GRUB?

Whoops! :) Leaving it out makes the process much faster, though. You
just don't get to keep your data. In my defence, vgreduce doesn't work
for PVs still in use.

And these are just warnings, too.

Look at the "/var/log/syslog" file, maybe there is something there :-?

When sutting down the network service you are telling the applications:

By Googling around I found this (comment #5):

This is indeed in the line of what Liam suggested, so try and check if

You certainly forget a pvmove of the partitions between vgextend and vgreduce.

I agree. On my windows box (and running iexplorer 8) I've been recently 
infected by a trojan that came from a java applet (yep, it was my fault), 
very annoying and hard to eliminate ;-(

Are most wireless routers that limited?

I'm still using the stock firmware on a WRT54GL and it allows me to set 
the DHCP IP address assignment range.  It was, I think, from 1 - 100 but 
I changed it to 100 - 150.

What I would probably do is:

- install new disk alongside the old one
- put one big partition on the new disk and pvcreate the partition
- vgextend the existing VG with the new partition
- vgreduce the VG, removing the old disk's partitions

That should be just as fast as dd'ing the old filesystems and can be
done without downtime. You don't need to resize any existing partitions,
but you can of course grow the LVs and the filesystems afterwards, if
you want to take advantage of the additional space.

clone LVM disk to a larger disk

[Peter Beck]

Hi guys,

I'm using two HP Microservers with a Heartbeat1 cluster, drbd and kvm.
On one of these servers the systemdisk is a 160GB disk with LVM 
configured, on the other node it's a 1TB disk. I'd like to have both 
nodes with the same disk sizes (easier to configure imo)


Now I've got a 1TB disk which I would like to use instead of the 160GB 
disk. My question: Can I just clone the small disk to the new large disk 
and then resize the LV on it ? Does that work ? I would say yes, but 
I've never done that, so I am not sure... ;)


Is there any advantage to use dd instead of Clonezilla[1], ReDo[2] or 
whatever ? Maybe dd is slower than the other tools, but other than that

there shouldn't be any issues, correct ?

Thanks
Best Regards
Peter

Wha is your point in mentionning this requirement ? Do you mean that the
server should not send packets bigger than 1280 bytes if it fails to
handle properly path MTU discovery ? If so, I fully agree.

Lowering the MTU at the client side does not fix the problem that exists
at the server side. It is just a workaround that works for TCP because
it happens that TCP uses the *outgoing* MTU to calculate the advertised
*incoming* MSS (how weird when you consider that internet routing is
likely to be asymmetric).

I'm planning a network share for unison backup, some other discrete backup
and media share, maybe with some virtualization to come, and found the pNFS
project (NFS 4.1): this seems experimental, exp. on the client side (
http://wiki.linux-nfs.org/wiki/index.php/PNFS_prototype_design), is that
true? on the debian side?

And found 2 that i sould go for openAFS... nobody experienced that on
debian? Particularly on a encrypted dm-luks/LVM system?

Thanks, Pier Paolo.

I restarted the process. Properly selected to execute the shell in
'lvm/hpdesk/root'. From within the shell:

grub-install /dev/sda

but upon reboot the grub list is empty ...

Not quite there, but making progress

re-installing grub (lvm)

[Mathieu Malaterre]

Hi all,

  After installing Windows 7, I lost my grub installation. I would
like to repair my grub installation. I prepared a bootable USB key
with a squeeze netinst iso. I can boot into 'rescue mode'. After
network autoconfiguration I can go to a shell, but when I type:

# grub-installer /dev/sda

It reports:

chroot: can't change root directory to /dev/sda: Not a directory

  Disk is simply: Win7 as primary partitation and the second one is
simply an LVM with /root, /home, / and swap (in this order).

Thanks a bunch !

I haven't looked at all into Kerberos, but sort of considering it. So I
was wondering, if it is worth (or even just work) when I just have a
server client network and no extra kerberos server? Or is Kerberos
rendered useless if I let it run on the same server that hosts the nfs
server?

Cheers,
Simon
