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
/data/user3/bids/noaa/runs/0128
res 31820 user3 cwd DIR 83,106 12288 39649281
/data/user3/bids/noaa/runs/0096
110510208 31847 user3 cwd DIR 83,106 12288 39649281
/data/user3/bids/noaa/runs/0096
110510208 31850 user3 cwd DIR 83,106 12288 39649281
/data/user3/bids/noaa/runs/0096
mpirun 31950 user3 cwd DIR 83,106 12288 39649281
/data/user3/bids/noaa/runs/0096
srun 31951 user3 cwd DIR 83,106 12288 39649281
/data/user3/bids/noaa/runs/0096
bash 32572 user1 cwd DIR 83,106 294912 393217 /data/user1
2. Unmount all Lustre file systems on the client node that you are going to upgrade, by entering the
following command:
# sfsumount -a
3. Remove all of the existing HP SFS RPM files on the client node, except the kernel, in the order in which
they were installed, as shown in the following example:
NOTE: For some distributions, the python-ldap package provided on the source media for
the distribution is not suitable for use with the HP SFS software. For these distributions, HP
provides a modified version of the python-ldap package in the appropriate directory for the
client architecture/distribution combination on the HP StorageWorks Scalable File Share Client
Software CD-ROM.
If a modified version of the python-ldap package is provided for your client architecture/
distribution on the HP StorageWorks Scalable File Share Client Software CD-ROM for the
version you are upgrading to, you must remove the existing version of the package and install
the appropriate version.
