Quantum 2.4.1 User Manual

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 -v command 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"
