 I never denied that such beasts exist. I just wanted to point out that a
 x86 machine with those mobos would come close in price to the alpha
 solution.
 I simply can't imagine that there are no alpha boxen with more than 2
 PCI busses. If I had a faster internet connection now, I'd check the web
 site of alpha-processor Inc.

I use a Siemens D111 board/chipset 450NX. It has 3 PCI buses.
It is a PIII/Xeon board, not very cheap but with one 64 bit PCI bus which
is done by coupleling two 32 bit PCI uses.

 1) as the error message also points out, that option is NOT to be sent
in email :)  privately? perhaps... a well-archived list? no :)
 
 2) we still don't have the mkraid output,

In the question mail there was a log file attached. There you could see
that the "forbidden to tell" command was not used.


 mdstat contents, syslog entries.
that mkraid option will do nothing for an unpatched kernel, something
we still don't know he's *not* running.

Re: Raid over Network

2000-01-31 Thread Jens Klaas

Quoted mail:
 
  Hi all,

Hi,

  I have 40 comps and have 2GB free partition each of them.
  I want to manage them on one comp in one directory.
  When I asked this question to linux-admin list, somebody told that there
  is a solution on this list with subject raid over network.
  If there is something like that, could anybody explain how I can do that?
  Or recommend any doc.
  Sorry for my english. 

I don't know if raid over network is possible, but perhaps PVFS (Parallel
Virtual File System) could be a solution for you. 
Sorry, but I don't remember where I got it from.

Raid 0 problems

2000-01-28 Thread Jens Klaas

Hi Gang,
I use the 2.2.11 kernel with the raid0145-19990824-2.2.11 patch.
It works fine as long as I don't let multiple user on the system.
Heavy load is not the problem, more the concurrent access. :(
The box crashed without any error message in any log file.

I compiled the 2.2.14 kernel without any patch. Now I can't start my raid,
even if the md driver are available.

Is raid0 with the patch and the kernel supported raid0 not the same format?

In the mkraid man page I read somethink about the old format. How can I get
more infos about the new format.

cu
Jens
