To do this, you will need to log into https://www.redhat.com/apps/support/ Hi, Gary. I concur with Suzanne on this one, especially since the issue might be related to something different installed with the update that is outside of the kernel. Support is in the best position to help you. In the meantime, I'll reassign this to a kernel engineer who knows about our disk susbsystems. But please let us know what answers you get back from Customer Support. Thanks. -ernie My guess is that this isn't a bug, but is a side effect of the prelink option we use on current systems. After a large number of RPMs are updated on disk, the system needs to redo the prelink cycle. This cycle would be disk intensive. It may be something else, but this is my first guess at the what's going on. No activity for over 6 months, closing. |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Description of problem: Disk Utilization %util spikes up to 100% right after upgraded the kernel from 2.4.21-9.0.3.EL to 2.4.21-15.EL. The high %util last about 12 hours and then goes down 10% and then spikes up to 45% after another 12 hours (see attachement 1). In fact the same behavior happened for the update of from 2.4.21-9.0.1.EL to 2.4.21-9.0.3.EL. (see attachment 2 [details]). I only see this heppens on ATA DISK drives not on SCSI Disk drives. Any ideas? Version-Release number of selected component (if applicable): 2.4.21-15.EL How reproducible: Always Steps to Reproduce: 1.update the kernel with the release of 2.4.21-15.EL 2. 3.
