All threads of a process must run on the same node at the moment - since 
threads generally communicate by shared memory performance of a 
multi-threaded program split across nodes would be horrible.

Use GFS or Lustre.  I don't think anyone is working on this at the 
moment, so the code has probably bit-rotted to oblivion.

This looks like the problem Sergi Barroso was running into.

What does /etc/blkid.tab look like?  Is it a CDSL (i.e. a symbolic link 
that looks like this:

$ ls -l /etc/blkid.tab
lrwxrwxrwx 1 root root 37 2009-03-19 13:24 /etc/blkid.tab -> /cluster/node{nodenum}//etc/blkid.tab

What does:

    find /cluster/ -name blkid.tab 2>/dev/null
      

show?

[SSI-users] adding new node

I'm got my server node installed. I'm at the point of running 'ssi-addnode'
when it gets to the end and go to write the config file, there is an error
message that "you should run ssi-create first."

I read this in the Wikipedia:

"OpenSSI is designed to be used for both high performance and high

single point of failure, for example the file system can be mirrored between

I've just done another reinstall, from scratch, and it all worked as 
expected, including the udev downgrade.

debian volatile is where they bung quick changing stuff like virus 
scanner patterns.  (I.E. stuff where the changes are not too large and 
you don't want to be forced to wait for the next update).

It gets installed in /etc/apt/sources.list by the standard install.

Having it should cause no problems.

As the commented install log is too big for SourceForge's mail system 
I've put a copy on deb.openssi.org.

You can see it at:

[SSI-users] Log of OpenSSI install on Debian Lenny

[John H. <jo...@Ca...>]

After the various problems people have been having installing OpenSSI on 
Debian Lenny I've retried it myself to see if it still works.

The good news is that the install worked more as less as expected.

One very strange thing is that this time the udev downgrade worked as 
expected.  I'm going to have to spend some time working out why it works 
now but didn't work before.

Here's the log.  I've had to gzip it to avoid Sourceforge message size 
limits.  I'll send an trimmed, commented version as another message.

This is too bizarre.  I'm trying a reinstall from scratch and it 
downgraded udev for me on the dist-upgrade.

Please could you try re-installing from the beginning, following my 
(modified) instructions to the letter.

If any step doesn't work, contact me immediately.

Re: [SSI-users] can't access public nic

[jhansen <jef...@gm...>]

Still "no joy"

this approach didn't work. It couldnt even mount the root file system at
reboot  :o

Re: [SSI-users] can't access public nic

[jhansen <jef...@gm...>]

.

What does:

    grep symlink /var/lib/dpkg/info/udev.postinst

show?

(For me it's:

# grep symlink   /var/lib/dpkg/info/udev.postinst                          
# create a default symlink if the directory exists and is empty
create_rules_symlink() {
  # make symlinks to the sockets and pipes on the old /dev
      create_rules_symlink

I got the same as you. So, I did the following from bash shell:
  . /var/lib/dpkg/info/udev.postinst abort-deconfigure (return)
  create_rules_symlink (return)

That seemed to work and I've got rules.d populated now. Next step is to
install openssi, i'll do that tonight and let you know how it worked.
Thanks!

This is so frustrating - I don't see why it works for me and not for you.

What does:

    grep symlink /var/lib/dpkg/info/udev.postinst

show?

(For me it's:

# grep symlink   /var/lib/dpkg/info/udev.postinst                          
# create a default symlink if the directory exists and is empty
create_rules_symlink() {
  # make symlinks to the sockets and pipes on the old /dev
      create_rules_symlink

Re: [SSI-users] can't access public nic

[jhansen <jef...@gm...>]

Getting closer but still not quite there.


So do an "apt-get install udev" to install version 0.80-1
    ok, this worked this time (wiered it didn't work first time i verified
that i did run it previously). and I got the warning message and installed
new packages. dpkg -l udev now shows version 0.80-1

Do you need this?  Why?
      This was here as part of the install. I commented this out.

I when to run the shell command line and I am still getting 
"sh: create_rules_symlink: ommand not found."
