  • FAS / AFF モデル

問題

monitor.shutdown.brokenDiskメッセージは、自動シャットダウン シーケンスがcallhome.shutdown.pendingごとに期限切れになったとき(指定された時間間隔でRAIDグループがデグレード モード状態にあったときデフォルトは通常24時間です)  

  • ノードは、次のエラーでテイクオーバーを実行せずにシャットダウンします:

例:

[node01: statd: monitor.brokenDisk.notice:info]: When two disks are broken in raid_dp volume, the system shuts down automatically every 24 hours to encourage you to replace the disk. If you reboot the system it will run for another 24 hours before shutting down. (The 24 hour timeout may be increased by altering the "raid.timeout" value using the "options" command.)
[node01: statd: monitor.shutdown.brokenDisk:EMERGENCY]: data disk,parity disk in RAID group "/aggr0_n1/plex0/rg0" are broken. Halting system now.
[node01: shutdown_thread0: ha.localNodeShutDown:notice]: Shutdown of the local node has been initiated with inhibit_takeover set to TRUE.
[node01: shutdown_thread0: kern.shutdown:notice]: System shut down because : "BROKEN DISK".

  • 同じRAID-DPグループの2本のディスクで障害が発生し、RAIDグループが「二重デグレード」状態になっています:

例:    

Aggregate aggr0_n1 (online, raid_dp, degraded) (block checksums)
  Plex /aggr0_n1/plex0 (online, normal, active, pool0)
   RAID group /aggr0_n1/plex0/rg0 (double degraded, block checksums)
