使用resize2fs時報錯：Couldn't find valid filesystem sup
發布時間：2023-10-18使用resize2fs時，提示如下異常
[root@dbserver /]# resize2fs -p /dev/mapper/data-oradata
resize2fs 1.42.9 (28-Dec-2013)
resize2fs: Bad magic number in super-block while trying to open /dev/mapper/data-oradata
Couldn't find valid filesystem superblock.
查詢資料確認到xfs格式的文件擴充需要使用xfs_growfs
[root@dbserver /]# xfs_growfs /dev/mapper/data-oradata
