mmlspdisk which Lists information for one or more GPFS Native RAID pdisks. To check faulty disks, do the commands
# mmlspdisk all --not-ok mmlspdisk: [I] No disks were found.
OR
# mmlspdisk all --replace mmlspdisk: [I] No disks were found.
We have encountered a situation where a defunct disk was accepting IO request and did not return any failure in time. As a result, these IO requests hanged there till time out (default 10 seconds). Typically, Spectrum Scale/GPFS will fail to read or write a disk, the failure is written in log and we have to shift IO to other available disks which should be quick.
Normally such operations should return in 20 milliseconds or less. When we have IO timeout, this request has wasted us
10 seconds / 20 milliseconds = 500 times of time. Even if Spectrum Scale/GPFS is able to choose a fast disk in the second attempt, we are much slower than normal.
Due to the utilization of striping technology, a bad/slow disks always affects IO of many files, much more than the situation without striping. IO on the same file involves more than several disks, and the IO has to wait for the slowest request to return. So a bad/slow disk may have considerable influence on Spectrum Scale/GPFS performance.
If the Gold Accounting System hanged by an unforeseen situation, there are 2 simple ways to start the services again
Step 1: Logon as postgres account
# su --login postgres
Step 2: Start the Gold Database
/usr/bin/postmaster -i -D /var/lib/pgsql/data > /var/log/pgsql 2>&1 &
Step 3: Start the gold Services
/opt/gold/sbin/goldd
If you have an error message when you launched FastX2 client, you will see this error “The command gnome-session existed with signal 15” on CentOS 7 for FastX2.
Step 1: This error is caused by selinux on CentOS 7. Do the following /etc/selinux
SELINUX=disabled
Trying to use the command “setenforce 0” does not seems to be able to fix the issue.
Step 2: Remember to install GNOME Desktop
# yum groupinstall "GNOME Desktop" "Graphical Administration Tools"
Step 3: Uninstall the StarNetFastX2 and reinstall
# rpm -e StarNetFastX2
# rpm -Uvh --force StarNetFastX2-2.4.7.rhel6.x86_64.rpm

Do note that firewall on CentOS 7 system is enabled by default.
Step 1: To check the status of CentOS 7 FirewallD
# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:firewalld(1)
The above shows that the firewalld is disabled.
Step 2: To stop the FirewallD
# systemctl stop firewalld.service
Step 3: To completely disable the firewalld service
# systemctl disable firewalld.service
If you are installing something and you see this “Error error while loading shared libraries: libXm.so.4”. It is quite easy to solve. Just do the following
# yum install motif, motif-devel
