[Gluster-users] timestamps getting updated during self-heal after primary brick rebuild

A small question: We know that one or two members of the dev team read these
emails. One said just yesterday he's more likely to see emails than bug
reports. Now, sometimes the response to an email showing an obvious bug is
"File a bug report please." But for something like this - yes timestamps are
data so this is a serious bug - it would be a healthy thing if someone on
the dev team would make a point of both acknowledging that it's a bug, and
taking responsibility for being sure the bug report is filed and assigned to
the right people, whether or not the email writer has taken that step.

If the team's too small to follow through like this, is someone advocating
with Red Hat for more staff? They've made a large investment in Gluster,
which they might want to protect by fully staffing it. It's the fault of the
firm, not current project staff, if the current staffing is too thin.

Apologies if these reflections are out of place in a community discussion.
But it's in the community's interest that Red Hat succeeds and profits from
its Gluster purchase.
