Glusterfs 块大小

Glusterfs 块大小

我正在尝试部署一个包含 12 个节点、每个节点 10 TB 的 gluster 集群,但是当我创建卷时,每个块仅创建 50GB,我想它必须具有整个磁盘空间。这是我的配置:

每个节点的磁盘配置:

NAME            MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda               8:0    0   9,1T  0 disk 
└─sda1            8:1    0   9,1T  0 part /bricks/brick1

Gluster 卷信息:

Volume Name: vol01
Type: Distributed-Replicate
Volume ID: 70de6c08-e133-406e-99b0-7284be67cf5f
Status: Started
Snapshot Count: 0
Number of Bricks: 6 x 2 = 12
Transport-type: tcp
Bricks:
Brick1: gfs01:/glusterfs/distributed
Brick2: gfs02:/glusterfs/distributed
Brick3: gfs03:/glusterfs/distributed
Brick4: gfs04:/glusterfs/distributed
Brick5: gfs05:/glusterfs/distributed
Brick6: gfs06:/glusterfs/distributed
Brick7: gfs07:/glusterfs/distributed
Brick8: gfs08:/glusterfs/distributed
Brick9: gfs09:/glusterfs/distributed
Brick10: gfs10:/glusterfs/distributed
Brick11: gfs11:/glusterfs/distributed
Brick12: gfs12:/glusterfs/distributed
Options Reconfigured:
transport.address-family: inet
nfs.disable: on
performance.client-io-threads: off

砖块的体积细节(仅 2 个,其余的具有相同的配置):

客户端挂载点(50*12=300GB):

gfs01:/vol01                              300G    13G  288G   5% /mnt/glusterfs

有什么想法吗?我遗漏了什么吗?

答案1

看起来砖块的磁盘安装在/bricks/brick1。但是您根据砖块的不同目录创建了卷,即gfs01:/glusterfs/distributed

您可能应该创建一个新的卷,如下所示:

# gluster volume create lotsofdata \
  replica 2 \
  gfs{01,02,03,04,05,06,07,08,09,10,11,12}:/bricks/brick1/data

# gluster volume start lotsofdata

确保已/bricks/brick1自动安装(通过/etc/fstabsystemd.mount)。然后您应该能够安装名为 的新卷lotsofdata并将内容复制vol1到那里。

目前您vol1正在使用逻辑卷中的空间/dev/mapper/centos-root。因此您需要删除vol1所有/glusterfs/distributed目录。
