Gluster 磚塊離線，日誌中出現錯誤

我已經用我的 shell 腳本在 /var/lib/glusterd 中用主機名替換了所有 IP 地址並重命名了配置（IP 到主機名）。之後我重新啟動了 Gluster Daemon 和卷。然後我檢查是否所有對等點都已連接：

root@GlusterNode1a:~# gluster peer status
Number of Peers: 3

Hostname: gluster-1b
Uuid: 47f469e2-907a-4518-b6a4-f44878761fd2
State: Peer in Cluster (Connected)

Hostname: gluster-2b
Uuid: dc3a3ff7-9e30-44ac-9d15-00f9dab4d8b9
State: Peer in Cluster (Connected)

Hostname: gluster-2a
Uuid: 72405811-15a0-456b-86bb-1589058ff89b
State: Peer in Cluster (Connected)

當我執行df命令時，我可以看到所有節點上安裝的捲大小發生變化，因此新數據即將到來。但最近我注意到應用程序日誌中的錯誤消息：

copy(/storage/152627/dat): failed to open stream: Structure needs cleaning
readfile(/storage/1438227/dat): failed to open stream: Input/output error
unlink(/storage/189457/23/dat): No such file or directory

最後，我發現一些磚塊離線了：

root@GlusterNode1a:~# gluster volume status
Status of volume: storage
Gluster process            Port  Online  Pid
------------------------------------------------------------------------------
Brick gluster-1a:/storage/1a    24009  Y  1326

NFS Server on gluster-1b      38467  Y  2435
Self-heal Daemon on gluster-1b    N/A  Y  2441

我能做些什麼呢？我需要修復它。

注意：所有四個節點的 CPU 和網路使用率大致相同。

我在 Freenode#Gluster 的 JoeJulian 的幫助下解決了這個問題。當我檢查程序列表時，有一些程序使用舊配置：/usr/sbin/glusterfsd -s localhost --volfile-id storage.11.111.111.11.storage-2b.... 執行此命令後：

killall glusterfsd ; killall -9 glusterfsd ; killall glusterd ; glusterd

情況已解決 - 所有磚塊都線上：

# gluster volume status
Status of volume: storage
Gluster process                     Port    Online  Pid
