Good afternoon,
we are an italian csp, and i am evaluating stratis as tier storage solution,
but i have some questions, can i ask you?
1. What happens when a generic new pool i create has 1TB space as
default, but what happens when it reachs the 1TB limit? It is just a false
limit?
2. Thin provisioning is great, but can i also trim the space once the
files are deleted? Otherwise that filesystem will run out of space sooner or
later.
Thank you.

If no filesystem limit is set (set using stratis fs set-fs-limit), the
filesystem should continue to grow as you start running out of space. If a
filesystem limit is set, it will not grow past the size you have set as the
maximum.

Are you referring to reclaiming space on the thin pool or shrinking the
filesystem? fstrim can be run on filesystems to reclaim space on the
thinpool after files have been deleted. This would be the recommended
action if you're concerned about that. We have discussions open about
supporting fstrim through a Stratis interface, but have not implemented it
yet. If you're talking about shrinking the filesystem, XFS does not fully
support shrink operations, so we recommend setting filesystem limits or
using no overprovisioning mode to avoid growing filesystems past the
maximum size you would like.
1.
Thank you.
