[問題] 請教glusterfs的問題
首先先簡單介紹一下配置
我手邊總共有四個VM(hadoop111、hadoop112、hadoop113、hadoop114)
且都有加入彼此的host對應IP的設定在/etc/hosts內,
四台的OS都是使用CentOS 5.6,且gluster安裝的版本均為3.3.2。
1.用glusterfs刪除volume碰到以下狀況:
[root@hadoop111 /]# gluster volume info
Volume Name: dist-vol
Type: Distribute
Volume ID: b8eefa6f-8cc6-435f-919d-b608e0419cef
Status: Created
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: hadoop113:/dist
Brick2: hadoop114:/dist
[root@hadoop111 /]# gluster volume delete dist-vol
Deleting volume will erase all information about the volume. Do you want to
continue? (y/n) y
Volume dist-vol does not exist
[root@hadoop111 /]#
明明用volume info查看是存在的,但是要刪除的時候卻會提示已經不存在了,
這樣的話要怎樣處理?
2.若是要在已經建立完成的volume上新增brick,會出現以下訊息
[root@hadoop111 /]# gluster volume info repli-vol
Volume Name: repli-vol
Type: Replicate
Volume ID: 592c815e-f34c-4a5b-93e6-47fa153a9173
Status: Created
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: hadoop111:/repli-vol
Brick2: hadoop112:/repli-vol
[root@hadoop111 /]# gluster volume add-brick repli-vol hadoop113:/repli-vol
Incorrect number of bricks supplied 1 with count 2
[root@hadoop111 /]# gluster volume add-brick repli-vol hadoop113:/repli-vol
hadoop114:/repli-vol
Host hadoop113 not connected
[root@hadoop111 /]#
系統會一直告知「沒有連結」的訊息,請問這在什麼情況下會發生?
煩請各位先進不吝解答,謝謝...

第二個我試出來了,但是必須在創造volume時不包含本機Host,
這樣才可以加入其他brick,
但是只要創造該volume時有用到本機Host,
加入brick時則一定會出現這種情況。但目前還不知道為啥..
