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 Node 192.168.7.86 has 1 volume(s) "/dev/sda" "7fc9d1ff2093a1810b74e444739bd837" has .138GB trapped, 1.256GB used, 8.723GB free, 10.119GB total, 23 streams, state "ok", trapped ratio: .984, largest stream UUID: "a085ddd6b287b04a5e4f9af61fce4ce7", largest stream in MB: 155, JournalBid: 0 Total Trapped: .138GB, Total Used: 1.256GB, Total Free: 8.723GB, Total Capacity: 10.119GB, Total Streams: 23 Elapsed time to run this script: 0 seconds root@b-csn7:~>curl -u "admin:caringo" "192.168.7.86/7fc9d1ff2093a1810b74e444739bd837?admin" -o uuids.7fc9d1ff2093a1810b74e444739bd837.txt % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 107 858 0 858 0 0 144k 0 --:--:-- --:--:-- --:--:-- 167k root@b-csn7:~>sort -u uuids.7fc9d1ff2093a1810b74e444739bd837.txt | wc -l 23
