In bug 1933756, Casey mentioned this is resolved in 2.8.1, so we could update EPEL 8 to that version instead. After discussion in #ceph-devel, I'm going to push to 2.7 with an epoch bump to epel8. Given that no other distros besides Fedora have updated to 2.8 and some other upstream maintenance factors, we need wider testing at this point. I would prefer that we not go backwards here. If this is fixed in 2.8.1, that would be an appropriate update. debian sid/bullseye currently has 2.8.1 OpenSUSE tumbleweed also has at 2.8.1 at present debian sid/bullseye currently has 2.8.1, ubuntu hirsute (21/04) currently has 2.8.1, OpenSUSE tumbleweed also has at 2.8.1 at present. I'm concerned with going to 2.8.1 since there may be further bugs that haven't appeared in ceph's stress testing yet. In the past we've seen several issues with updates to tcmalloc in ceph. All the distros using 2.8.1 are bleeding edge/unreleased, so it has little real-world exposure. What benefit to updating to 2.8.1 is there? It seems high risk, for little reward to me. What's odd is that 2.8 is in F33, but AFAICS no such bugs have been raised against it. If we revert to 2.7, then the P&Z fixes will need to be backported, and ceph.spec updated yet again to reflect that. Yes, we would need to backport P&Z fixes to 2.7-6 to avoid regressing on those arches. Several engineers from multiple teams did testing on gperftools 2.8. They reported their results in Bodhi at https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2021-dd6932436d . The problem is that this testing was not heavy enough stress testing to shake out this particular issue, and in the absence of further information, we're now stuck wondering about unknown-unknowns. Next time we have to update gperftools in EPEL, we'll coordinate longer testing with Teuthology in the main upstream ceph lab.
