Re: List ISILON configuration
Not really. Things can get quite sophisticated, like changes via sysctl.
(and while sysctl *can* list all its contents at once with -a, better do not try that here,
as it spills out too much runtime stuff.)
Keeping outside the cluster a copy of a recent isi_gather_info tar-file
might help when recovering many settings after a disaster, but that would
require some reverse engineering of the way isi_gather_info
organizes its stuff.
As a practical advise: make a priority list of the
individual config areas, and then work through the CLI tools
from top to bottom to see how things can be collected.
Usually there exist "list" subcommands which you
might want to decorate with a -v/-l/-w (verbose/long/wide)
It's far from perfect (leave alone the question how to
re-establish settings from those lists), but within an hour
or so you might be able to cover most of the relevant things.
Digging deeper into the last bits will get tedious, though.
