所以我有以下设置：

[ec2-user@ip-172-31-9-177 ~]$lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0  80G  0 disk 
├─xvda1 202:1    0   6G  0 part /
└─xvda2 202:2    0   4G  0 part /data

我发现的所有教程都说使用xfs_growfs< mountpoint>但这没有效果,也没有-d选项：

[ec2-user@ip-172-31-9-177 ~]$sudo xfs_growfs -d /
meta-data=/dev/xvda1             isize=256    agcount=4, agsize=393216 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=0
data     =                       bsize=4096   blocks=1572864, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=0
log      =internal               bsize=4096   blocks=2560, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0
data size unchanged, skipping

我应该补充说我正在使用：

[ec2-user@ip-172-31-9-177 ~]$cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.0 (Maipo)
[ec2-user@ip-172-31-9-177 ~]$xfs_info -V
xfs_info version 3.2.0-alpha2
[ec2-user@ip-172-31-9-177 ~]$xfs_growfs -V
xfs_growfs version 3.2.0-alpha2

解决方法:

你有一个4GB xfs文件系统在4GB分区上,所以没有工作要做.

要克服,请使用parted扩展分区,然后使用xfs_growfs扩展fs.您可以使用parted rm而不会丢失数据.

# umount /data
# parted
GNU Parted 3.1
Using /dev/xvda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) unit s
(parted) print
....
(parted) rm 2
(parted) mkpart
....
(parted) print
(parted) quit

# xfs_growfs /dev/xvda2
# mount /dev/xvda2 /data

完成.无需更新/ etc / fstab,因为分区号相同.
