Hi Jody,

Aside from the '/nsr/debug/striped_recover' trick (SWEEEET!). Quite often we
recover 500 GB by specifying multiple SSID's via the CLI.  ie. 'recover -s
lgto_server -d /some/remote/path -S 1234 -S 6789 -S 9876'.

This atleast reads/restores streams that were written in parallel on the same
volume.

Regards,
