Re: [lustre-discuss] Setting infinite grace period with soft quotas
Cameron, could you please file an LU ticket for that so it isn't lost. Thanks. Cheers, Andreas > On May 9, 2019, at 08:55, Harr, Cameron wrote: > > Thanks Andreas.

Judging by the lack of response, I don't think anyone has tried this, but it also seems like something that could be tested quite easily?

Re: [lustre-discuss] Setting infinite grace period with soft quotas
Thanks Andreas. This is somewhat interesting in that I don't have such a man page on the systems and 'man lfs' doesn't have such a statement. But, certainly, 2^48 sec. would be sufficient! Our workaround was just to use a -t XXXw to specify a large number of weeks (largest granularity I could see) for the grace period, but having a '-1' shortcut would be preferable.

Re: [lustre-discuss] Setting infinite grace period with soft quotas
I do see in the lfs setquota usage message and lfs-setquota.1 man page: "The maximum quota grace time is 2^48 - 1 seconds." That's about 9M years, so it should probably be long enough? It might make sense to map "-1" internally to "(1 << 48) - 1" to make this easier.

Re: [lustre-discuss] Setting infinite grace period with soft quotas
I had tested first and couldn't find a way to do so, so I was curious if there was some undocumented way. I'm proceeding with, "No, there's not a way."

[lustre-discuss] Setting infinite grace period with soft quotas
We're exploring an idea where we keep soft quotas enabled so that users will be notified they're nearing their hard quotas (via in-house scripts), but users don't like that the soft quota becomes a hard block after the grace period. I can understand their rationale as well that they should be able to write up to their hard quota always. Is there a way to set the grace period as unlimited (e.g. lfs setquota -t -1 ...)?
