Quantum 2.4.1 manual Smp

Operating System/		Description
Component Affected
Linux	StorNext FS is shipped as separate, installable versions for the
	Uniprocessor (up) and Multiprocessor (smp) Linux kernel versions. You
	need to select the correct kernel version of StorNext FS. Otherwise you will
	encounter problems during installation and while running the product.
	Use the uname -vcommand to determine the running version of Linux.
	The version includes the string smp for multi-processor kernels.
	• For up kernels, the StorNext FS RPM files for the server and client code
		must have up in the RPM file name.
	• For smp kernels, the StorNext FS RPM files for the server and client code
		must have smp in the RPM file name.
	The following are examples of Linux RPM file names for up and smp
	kernels.
	•	up:
		cvfs-client_7.1_2417up-2.1.1-63.i386.rpm
		cvfs-server_7.1_2417up-2.1.1-63.i386.rpm
	•	smp:
		cvfs-client_7.1_2418smp-2.1.1-63.i386.rpm
		cvfs-server_7.1_2418smp-2.1.1-63.i386.rpm
	On many versions of Linux, the cron system runs a nightly script called
	slocate.cron that is used to build a database used by the slocate
	command. If StorNext file systems are mounted, they will be traversed by
	this cron job which can have a dramatic impact on the performance of other
	applications currently using these file systems. To prevent cron from
	traversing StorNext file systems, two files need to be updated. Perform
	these steps:
	1	Modify the updatedb command in the /etc/cron.daily/slocate.cron file to
		read:
		/usr/bin/updatedb -f
		"cvfs,nfs,smbfs,ncpfs,proc,devpts" -e
		"/tmp,/var/tmp,/usr/tmp,/afs,/net"
		NOTE: "cvfs" has been added to the exclude list.
	2	Add cvfs to the PRUNEFS definition in the /etc/updatedb.conf file.
		For example:
		PRUNEFS="cvfs devpts NFS nfs afs proc smbfs autofs
		auto iso9660"
