Hi everyone,
I had a server doing a cache scan for over an hour yesterday after upgrading the RAID (mpt2sas) driver on RHEL5.5 64bit. I thought the box hung, so I ran a hard reset and ended up rebuilding it. I'm trying to reproduce and measure the cache scan time with the two different versions of the RAID driver to see if the driver causes an issue, or not. How can I force the client to run a cache scan when I run /etc/init.d/openafs-client restart instead of at boot time? I'm trying the following procedure to benchmark things: fs setcachesize 1 fs setcachesize 62048980 fs getcachep cd /afs/(some folder) find . -type f | xargs cat > /dev/null cd / time /etc/init.d/openafs-client restart Details on production box: OS: RedHat Enterprise Linux Server 5.5 (64bit) Hardware: Dell PowerEdge R210 With H200 RAID controller Driver: mp2tsas driver from Dell Details on testing box (my only H200 cards are in production servers): OS: RedHat Enterprise Linux Server 5.5 (64bit) Hardware: Dell PowerEdge R510 With H700 RAID controller Driver: mp2tsas driver from Dell Thanks, Jason ------------------------------------------------------------------------ --- Jason Edgecombe | Linux and Solaris Administrator UNC Charlotte | The William States Lee College of Engineering 9201 University City Blvd. | Charlotte, NC 28223-0001 jwedg...@uncc.edu <mailto:jwedg...@uncc.edu> | http://coe.uncc.edu <http://coe.uncc.edu/> | <https://www.facebook.com/UNCCEngr> Facebook <https://www.facebook.com/UNCCEngr> ------------------------------------------------------------------------ --- If you are not the intended recipient of this transmission or a person responsible for delivering it to the intended recipient, any disclosure, copying, distribution, or other use of any of the information in this transmission is strictly prohibited.
