Installing and configuring Red Hat Enterprise Linux and SUSE Linux Enterprise Server 9 SP3 client systems3–20

3.4.1 Step 1: Upgrading the HP SFS client software

To upgrade the HP SFS client software on RHEL and SLES 9 SP3 client systems, perform the following steps:

1. On the node that you are going to upgrade, stop all jobs that are using Lustre file systems.

To determine what processes on a client node are using a Lustre file system, enter the fuser

command as shown in the following example, where /data is the mount point of the file system. You

must enter the command as root user; if you run the command as any other user, no output is

displayed:

# fuser -vm /data

USER PID ACCESS COMMAND

/data root 303 ..c.. su

user2 10993 ..c.. csh

user2 16408 ..c.. ssh

user3 22513 ..c.. csh

user3 31820 ..c.. res

user3 31847 ..c.. 1105102082.1160

user3 31850 ..c.. 1105102082.1160

user3 31950 ..c.. mpirun

user3 31951 ..c.. srun

user1 32572 ..c.. bash

Alternatively, you can enter the following command (enter the command as root user; if you run the

command as any other user, the command only reports the current user’s references):

# lsof /data

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME

su 5384 root cwd DIR 83,106 294912 393217 /data/user1

csh 10993 user2 cwd DIR 83,106 4096 52428801 /data/user2/bonnie

ssh 16408 user2 cwd DIR 83,106 4096 52428801 /data/user2/bonnie

csh 22513 user3 cwd DIR 83,106 4096 39682049
