Cause

Causada por um problema conhecido PSCALE-62304, resolvido na versão 9.1.0.13 (patch de novembro) e também na versão 9.2.0.0
(resolvido no patch 9.1.0.13: [9.1.0.13_GA-RUP_2021-11][Várias correções de espaço do usuário e kernel](novembro de 2021)

A reinicialização de pane inesperada é causada por uma condição de corrida ao liberar um cache de um inode de estatísticas de cluster de uso interno.
Esse problema no código foi corrigido nas seguintes versões ou posteriores:

  • OneFS 9.1.0.13 via PSCALE-62304
  • OneFS 9.2 via PSCALE-49586
  • OneFS 9.3 via PSCALE-50848
