Use this procedure to determine why the rgw health check failed and what needs to be fixed.
In the goss test output, look at the value of x in Expected \< int \>: x (possible values are 1, 2, 3, 4, 5). Based on the value, navigate to the corresponding numbered item below for troubleshooting this issue.
Optional: Manually run the rgw health check script to see descriptive output.
ncn-m001# GOSS_BASE=/opt/cray/tests/install/ncn /opt/cray/tests/install/ncn/scripts/rgw_health_check.sh
A value of 1 is returned if unable to connect to rgw-vip. This happens if any of the following three commands fail.
ncn-m001# curl -i -s -S -k https://rgw-vip.nmn
ncn-m001# curl -i -s -S http://rgw-vip.nmn
ncn-m001# curl -i -s -S http://rgw-vip.hmn
Log into a storage node and look at the version and status of Ceph.
ncn-s# ceph --version
ncn-s# ceph -s
A value of 2 is returned if a storage node is not able to be reached. In this case, run the rgw_health_check.sh as stated in the optional step above. Find which storage nodes are not able to be reached, and run the following checks on those nodes.
Check if HAProxy is running on the node.
ncn-s# systemctl status haproxy
If HAProxy is not running, restart it and check the status again.
ncn-s# systemctl restart haproxy
ncn-s# systemctl status haproxy
Check if keepalived is running on the node.
ncn-s# systemctl status keepalived.service
If keepalived is not running, restart it and check the status again.
ncn-s# systemctl restart keepalived.service
ncn-s# systemctl status keepalived.service
Check if the ceph-rgw daemon is running.
ncn-s# ceph -s | grep rgw
If the ceph-rgw daemon is not running on 3 storage nodes, restart the daemon and watch it come up within a few seconds.
ncn-s# ceph orch ps | grep rgw #use this to wach the daemon start
ncn-s# ceph orch daemon restart <name>
A value of 3 is returned if a craysys command fails. This implies ‘cloud-init’ is not healthy. Run the command below to determine the health.
ncn-s# cloud-init query -a
If the command above fails, reinitialize ‘cloud-init’ using the following command.
ncn-s# cloud-init init
If a value of 4 or 5 is returned, then rgw-vip and the storage nodes are reachable. The error occurred when attempting to create a bucket, upload an object to a bucket, or download an object from a bucket. This implies Ceph may be unhealthy. Check Ceph status with the following command.
ncn-s# ceph -s
If Ceph reports any status other than “HEALTH_OK”, refer to Utility Storage for general Ceph troubleshooting.
