Hello, Devs. I observe interesting restore failure on SolrCloud 6.6. When the second replica (1) is added, it recovers from the first one (0), which is expected to be restored already. It usually fine, but quite regularly it recovers from empty replica, like it happens before restore is done. I briefly checked overseer log it expose enough level of sanity: adding the second happens after the first one's recovery.
Have you seen such sort of race-condition? -- Sincerely yours Mikhail Khludnev
