We patch the Red Hat 7.3 errata kernels with 1.0.24 JFS. The process is straight forward enough. You may have to tweak this for your environment. 1) Run rpm -Uvh kernel-source-$version-i386.rpm 2) cd to /usr/src/ 3) cp -a linux-$version linux-$version.ORIG 4) Download the full jfs-2.4-$version.tar.gz release to /usr/src/ 5) Run cd linux-2.4; tar -xzvf ../jfs-2.4-$version.tar.gz 6) cd /usr/src/ 7) Run diff -urNP linux-$version.ORIG linux-$version > /tmp/ltcjfs-$version.patch 8) Run rm linux-$version; mv linux-$version.ORIG linux-$version 9) Use the /tmp/ltcjfs-$version.patch in the kernel src.rpm The ltcjfs-$version.patch file should update the Red Hat included JFS to what ever version you downloaded. Just rebuilt the kernel.src.rpm for the arch you want and you're ready to go. On a related note, JFS 1.0.24 on Red Hat 7.3 has been very good to us under heavy load. We use it on the 600GB partition of our ftp3 server and it takes a beating without any stability issues.. -- Scott Russell <[EMAIL PROTECTED]> Linux Technology Center System Admin http://ltc.linux.ibm.com/ _______________________________________________ Jfs-discussion mailing list [EMAIL PROTECTED] http://www-124.ibm.com/developerworks/oss/mailman/listinfo/jfs-discussion
