Getting Started
Our engineering team can perform the health-check without remote access. In order for them to complete the report they will need you to perform the following steps.
Please provide the output of the following commands ran as root from ALL cluster nodes:
If your cluster is using Pacemaker:
----
sudo crm_report --from "$(date -d "30 days ago" +"%Y-%m-%d %H:%M:%S")" /tmp/crm_report_${HOSTNAME}_$(date +"%Y-%m-%d")
----
Note: The crm_report utility will generate a tar.bz2 file with all the pertinent configuration files, the current cluster status, as well as logs from a specified time-frame.
If you cannot provide the crm_report, or are only using DRBD, please run the following commands on all nodes:
----
cat /proc/drbd > /tmp/healthcheck-$HOSTNAME-drbd-state.txt
drbdadm dump all > /tmp/healthcheck-$HOSTNAME-drbd-configs.txt
cp /var/log/messages /tmp/healthcheck-$HOSTNAME-messages
rpm -qa > /tmp/healthcheck-$HOSTNAME-rpm.txt
ifconfig > /tmp/healthcheck-$HOSTNAME-ifconfig.txt
dmesg > /tmp/healthcheck-$HOSTNAME-dmesg.txt
sysctl -a > /tmp/healthcheck-$HOSTNAME-sysctl.txt
----
If you are using DRBD 9.x:
----
drbdadm status > /tmp/healthcheck-status_drbd_$HOSTNAME.txt
----
If network bonding is used:
----
cat /proc/net/bonding/bond0 > /tmp/healthcheck-proc_bonding_bond0_$HOSTNAME.txt
----
Kernel settings and DRBD kernel module information:
----
sysctl -a > /tmp/healthcheck-sysctl_$HOSTNAME.txt
cat /proc/drbd > /tmp/healthcheck-proc_drbd_$HOSTNAME.txt
----
If running a LINBIT SDS Cluster then run the following commands:
-----
llinstor --version >> /tmp/healthcheck-linstor-output.txt
llinstor node list >> /tmp/healthcheck-linstor-output.txt
llinstor physical-storage list >> /tmp/healthcheck-linstor-output.txt
llinstor storage-pool list >>/tmp/healthcheck- linstor-output.txt
llinstor resource list >> /tmp/healthcheck-linstor-output.txt
lllinstor volume list >> l/tmp/healthcheck-instor-output.txt
linstor sos-report download
-----
If running a LINBIT vSAN Cluster then run the following commands:
Please note the last two commands should be ran on all three nodes.
-----
llinstor --version >> /tmp/healthcheck-linstor-output.txt
llinstor node list >> /tmp/healthcheck-linstor-output.txt
llinstor physical-storage list >> /tmp/healthcheck-linstor-output.txt
llinstor storage-pool list >>/tmp/healthcheck- linstor-output.txt
llinstor resource list >> /tmp/healthcheck-linstor-output.txt
lllinstor volume list >> /tmp/healthcheck-instor-output.txt
linstor sos-report download
linstor-gateway check-health >> /tmp/healthcheck-instor-output.txt
cp /var/log/messages /tmp/healthcheck-$HOSTNAME-messages
dmesg >> /tmp/healthcheck-$HOSTNAME-dmesg.txt
-----
Tarball the outputs and send us the /tmp/linbit-healthcheck.tar.bz2:
----
tar cjf /tmp/linbit-healthcheck.tar.bz2 /tmp/healthcheck-*
----
We will send you the health-check report once it is complete. If you have any questions, please let your account manager know.
