TAG DESCRIPTION EXAMPLE
====================================================================================================================================================================================
...
odf-clicmd To provide cli command execution from rook-ceph-operator in openshift-storage namespace -m odf-clicmd:mc.cfg -n 'CLICMD="rados lspools"'
odf-healthcheck To collect health/storage data from rook-ceph-operator in openshift-storage namespace -m odf-healthcheck:mc.cfg
odf-healthreport To collect 'ceph report' output from rook-ceph-operator in openshift-storage namespace -m odf-healthcheck:mc.cfg
odf-osddump To collect 'ceph osd dump' output from rook-ceph-operator in openshift-storage namespace -m odf-healthcheck:mc.cfg
odf-rados-bench To collect 'rados bench -p ocs-storagecluster-cephblockpool 10 write' output -m odf-rados-bench:mc.cfg
(2) To obtain a comprehensive healthcheck report of ODF:
./waiops-mustgather.sh -RMm odf-healthcheck:mc.cfg
The ODF healthcheck involves the following commands:
ceph status
ceph df
ceph health detail
ceph healthcheck history ls
ceph osd tree
ceph osd df tree |
(3) To obtain output of "ceph report" command:
./waiops-mustgather.sh -RMm odf-healthreport:mc.cfg
(4) To obtain output of "ceph osd dump" command:
./waiops-mustgather.sh -RMm odf-osddump:mc.cfg
(5) To test write (I/O) performance of Ceph storage:
./waiops-mustgather.sh -RMm odf-rados-bench:mc.cfg
(6) All of the above please!
./waiops-mustgather.sh -RMm odf-healthcheck,odf-healthreport,odf-osddump,odf-rados-bench:mc.cfg
(7) Anything else but the above?
If you have a need to execute command(s) not covered by the above, you can also do this:
./waiops-mustgather.sh -DRMm odf-clicmd:mc.cfg -n 'CLICMD="<CMD>"'
Eg.
./waiops-mustgather.sh -RMm odf-clicmd:mc.cfg -n 'CLICMD="rados lspools"'
