[Linux-cluster] Re: Linux-cluster Digest, Vol 38, Issue 25



Hi All,
 
I have intall globus on ma PC. I have done everything but when I run the command
 
root host:# etc/init.d/globus-4.0.4 start
 
I gave me the error that
libglobus_common_gcc32.so.0. No such file or directory
When I downloaded this file and run the command again, then problem came that:
ltdl_common_..... No such file or directory
When I downloaded it again and run the command again now then this error comes
 
/usr/local /sbin/globus-start-container-detached undefined symbol lookup error: globus_callback_space_reference.
 
so can anyone help me that why this error comes to me and how can I fix this.
 
take Care
Thanks
Faiz.

I am trying to setup CommuniGate
(http://www.stalker.com/content/default.html) as a cluster service. I have
everything working except for one thing. If I stop/kill the process
manually and wait for the status check to move the service nothing happens.


I get "clurgmgrd: [3087]: Executing /etc/init.d/CommuniGate status"
rather than the "clurgmgrd: [3087]: script:httpd-webcal: status of
/etc/init.d/httpd-webcal failed (returned 3)" I get with an apache process.

I had to add the "status" part to /etc/init.d/CommuniGate file myself, but
there is obviously a problem. I have mucked around with it for a while but
I am just putting it out there if my mistakes are obvious.

I have 4 servers each with their own harddrive.
I would like to setup gfs so that each can read/write
to their local harddrive and the data synced to the other 3 harddrives.
My original idea was to export all 4 harddrives with a network block
device like iscsi/gnbd/nbd and then use md software raid1 on top of
those but I've heard that this is a bad idea as md is not cluster aware.
I also found drbd but it only supports 2 harddrives.

Are there any available solutions for doing a 4 way mirror like I
am looking for? Basically a network raid 1 across 4 harddrives
on 4 separate systems.


Thanks,


Jon.
