resize2fs: 報錯

報錯如下

[root@localhost ~]# resize2fs /dev/mapper/centos-root
resize2fs 1.42.9 (28-Dec-2013)
resize2fs: Bad magic number in super-block while trying to open /dev/mapper/centos-root
Couldn't find valid filesystem superblock.

resize2fs: Bad magic number in super-block while trying to open /dev/mapper/centos-root錯誤

需要修改命令使用xfs_growfs /dev/mapper/centos-root
如下

[root@localhost ~]# xfs_growfs /dev/mapper/centos-root
meta-data=/dev/mapper/centos-root isize=512    agcount=4, agsize=2509824 blks
         =                       sectsz=512   attr=2, projid32bit=1
