格式化 drbd 报错 mke2fs -j /dev/drbd0 mke2fs: 错误的介质类型 while trying to determine filesystem size 有大用

mke2fs: 错误的介质类型 while trying to determine filesystem size

原因是您在辅助节点上,而/ dev / drbd0是只读的.切换到主节点,然后重试.

[root@node1 drbd.d]# drbd-overview        #看到了吧 ,本节点是 Secondary  ,不是主节点 

  0:mydrbd  Connected Secondary/Secondary UpToDate/UpToDate C r-----

[root@node1 drbd.d]# drbdadm -- --overwrite-data-of-peer primary mydrbd        #设置主节点 

[root@node1 drbd.d]# drbd-overview        #此时本节点是主节点 Primary

  0:mydrbd  Connected Primary/Secondary UpToDate/UpToDate C r-----

[root@node1 drbd.d]# mke2fs -j /dev/drbd0   #此时能正常格式化
