我承认我目前处于实验阶段,但当我阅读文档时,这应该不是问题。我正在通过 LVM 配置 DRBD。
据我了解drbd00.res
,我应该以 的身份访问该设备/dev/drbd00
。但是,该设备不存在。相反,/dev/drbd0
存在。但是,当我 时mkfs -t xfs on /dev/drbd0
,下次启动时状态将变为无盘。我的步骤如下:
pvcreate /dev/sdc1
vgcreate shared1 /dev/sdc1
lvcreate --name shared1 -l 100%FREE shared1
drbdadm create-md drbd00
systemctl start drbd
drbdadm primary drbd00 --force

[root@linclust1 ~]# mkfs -t xfs /dev/shared1/shared1
mkfs.xfs: cannot open /dev/shared1/shared1: Device or resource busy

[root@linclust1 ~]# cat /proc/drbd
version: 8.4.5 (api:1/proto:86-101)

我重新启动后它就进入无盘状态。

文件如下drbd00.res
:
resource drbd00 {
device /dev/drbd00;
disk /dev/shared1/shared1; <=== This is an lvm device
meta-disk internal;
syncer {
verify-alg sha1;
}
on linclust1.localdomain {
address 192.168.31.101:7789;
}
on linclust2.localdomain {
address 192.168.31.102:7789;
}
}
答案1
好的,我找到了问题所在。我尝试将其作为文件系统挂载,并通过 lvm 名称引用它,这使其变为无盘。我需要使用 /dev/drbd0 挂载它。这样就没问题了。
