How do I list the UUIDs on a volume?

Caringo Support may ask you about the contents of a particular volume. Following are two ways to get information.

List of UUIDs

Note

This method can take a while and has been known to timeout for densely loaded disks.

Assume a volume ID is 5e3fe929f3a393a99c9bee63ad10edbc (as seen in the storage console) and the NODE IP where it lives is 192.168.7.84:

curl -u"admin:caringo" -L "192.168.7.84/5e3fe929f3a393a99c9bee63ad10edbc?admin" -o [outfile filename]

This command requires administrative credentials. It will dump a list of all streams that are on that disk.

Count of streams

Here's an example using a script supplied in the Support Tools Bundle: swarm-support-tools.tgz Run the script with these options:

snmp-castor-tool.sh -t -n

root@b-csn7:~>cat NODES.csv
192.168.7.86
root@b-csn7:~>snmp-castor-tool.sh -t -n
Showing a detailed collection of statistics per disk for each selected node/ cluster
