Hi Avi
Greatly appreciated your help
Thank you very much. I have had look into the yum side, rebuild the rpm db
still no luck. As you suggested, i will need to see the less packages rpms
instead.
Thanks again for your help and time.
Best RegardsMalla

Hi,
Spacewalk does not create the SQLite databases that yum uses, so the first
thing yum has to do is rebuild those databases on the client and this is
particularly time-consuming on virtual OL5 guests.
Are these machines subscribed to ol5_latest? If so, I would strongly recommend
replacing that channel with a combination of ol5_u11_base and ol5_u11_patch
from ULN instead. Those two channels are significantly smaller and will be much
easier for the client to rebuild during an rhn_check run.
Alternatively, you can bind mount /var/cache/yum to a RAM disk so that the disk
usage is non-existant. This will also dramatically improve performance.
Hope that helps,Avi

Hi Guys
Greatly appreciated for your time.
I have a issue during spacewalk client add to the spacewalk master server.
We have staging server where all the VMs are connected to the Oracle SAN
storage (Entry Level)
When i am trying to add the client to the spacewalk server, there's too much
I/O generating the rhn_check process some times it's writing more than 50M
data, this process is mainly reading/ writing kjournald and Audit. because of
this system process reached to 100% waiting 80%. The client is completely not
responding hence over the monitoring system HOST DOWN alert appeared.
I have tried with --norhnsd option, still no luck. Is there a way to minimize
the rhn_check process? is there a way to stop generating too much I/O?
Could you please suggest some idea here?
But noticed there's a huge difference with the OEL6. it took roughly 5min time
to add the clinet.
Guys, pelase help me to address this issue, your help is very much appreciated.
Thank you all for you timeBest
