Hi Dan,

Thanks for the advice. Is it possible to get a bit more information on what is the risk of this bug? I tried to read the issues you referenced and the other referenced in the Issues but I didn't get the full picture... Is it just an osd crash or is there a risk of data corruption? I'm afraid it is more the last one...

Cheers,

Michel

Hi Michel,

19.2.2 should be immune from this bug, but I don't know if 19.2.2 has
enough real life usage to check for other potential issues.

We're working on an 18.2.7 hotfix now -- my personal suggestion is to
wait for that.

Cheers, Dan

Hi Dan,

bad luck, we just upgraded today! Is it so severe that we should plan to downgrade to 18.2.4 if feasible? Or if the issue is not present in Squid, to upgrade to 19.2.2?

Best regards,

Michel

Hi all,

Just a quick heads up -- 18.2.6 has a bluefs regression [1] which was
not present in 18.2.4.
Please avoid upgrading until further notice.

Regards, Dan
