swarmctl -t Disk related statistics

Note

The old fields (usedBytes, trappedBytes, and usedSpace) are deprecated and will be removed in a future release. The new fields (usedMBytes, trappedMBytes, and usedSpaceMB) have been introduced as their replacement.

swarmctl -t gives specific details on each disk on a node
Use -a -x to get more disk statistics for all nodes in the cluster.
Great for seeing changes over time and tracking potentially bad disks. Can use this as part of a cron job.
trappedBytes is measured in MB.
