Description peter ducai 2020-08-12 11:09:04 UTC
Description of problem:

Customer following https://access.redhat.com/solutions/4929021 gets error. As i'm working on sev1 case, I need well tested and working tool to benchmark ETCD as customer are sometimes overloading servers without properly scaling up the performance of storage.

Another suggestion could be to use dd as mentioned in 02657219 (and notes below). As dd is part of RHCOS/RHEL, maybe we should ditch Toolbox (as it's other team(?) responsibility) and go with most simple and stable solution.

ps: Frankly I don't care which tool will be chosen, but let's make sure it's well tested with every release and it's well documented. 

Justification for HIGH severity of BZ:
Suggesting tool that may or may not work, doesn't help with sev1 cases when troubleshooting speed is crucial, and also doesn't make us look good in customer's eyes as we're suggesting the solution that doesn't work. Please make choosing proper tool and documenting it's use priority. thanks a lot.

Actual results:


Expected results:

No matter what tool we suggest, I expect it to be well tested and working.. and ideally put in our documentation (in new troubleshooting part as in 4.5).


Additional info:

See 02657219 and comments #220 #230 for using dd as another option

Comment 2 Steve Milner 2020-08-12 14:33:30 UTC
Tested toolbox on 4.5 and hit no issue/could not reproduce the problem. On 4.3 I _do_ hit the issue. You're report looks like a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1850230. For benchmarking etcd I have to defer to the judgement of the etcd team/developers. If the tooling they expect to be available can not be installed on RHEL or Fedora containers please follow up with them. 

Marking as a duplicate.
