shadowstat - report shadow migration statistics
The shadowstat utility reports statistics on in-progress shadow migrations. A line of output is presented for each migrating file system; the output looks similar to the following:
EST BYTES BYTES ELAPSED DATASET XFRD LEFT ERRORS TIME pool/newfs 2.10M 28.8G - 00:02:45
Each line identifies bytes transferred thus far, a rough estimate of bytes left to transfer, number of migration errors, and the time elapsed since the migration was started.
If count is unspecified, updated values are presented every few seconds until the program is terminated. If count is specified, updates only occur count times, after which the program exits.
