[Lustre-discuss] Anyone using ACLs?

[Tina Friedrich]

Hi Craig,

assuming you're talking POSIX ACLs, they do, yes. We use ACLs (and
default ACLs) a lot.

One caveat being that we found that Lustre has a hard limit of 32 ACLs
on a file - this is, we believe, something that ext3 used to have (but
no longer has).

But if you don't need to set more than 32 ACLs on anything, not a problem.
