展开Raid后，在CentOS上调整XFS大小

我有一个使用xfs文件系统的Raid 6arrays上的16TB分区。

# df -hT Filesystem Type Size Used Avail Use% Mounted on /dev/sdc1 xfs 15T 7.4T 7.2T 51% /backup 

在添加了几个磁盘之后，我使用LSI Megaraid工具重build了RAID，虚拟驱动器在Megaraid中从16TB扩展到了29TB。 但是，当我尝试增长xfs系统时，大小没有改变。 命令“xfs_growfs / backup”立即返回，没有任何改变。

 # xfs_growfs /backup meta-data=/dev/sdc1 isize=256 agcount=15, agsize=268435455 blks = sectsz=512 attr=2, projid32bit=0 data = bsize=4096 blocks=3906469376, imaxpct=5 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 log =internal bsize=4096 blocks=521728, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 

我试过分手，也无法检测到新的尺寸。

 (parted) print /dev/sdc Model: LSI MR9271-4i (scsi) Disk /dev/sdc: 16.0TB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 16.0TB 16.0TB xfs primary 

以前，我遵循这个指令来创buildXFS分区。 我没有使用LVM。

更新我刚刚重新启动服务器，现在我可以看到分区是32TB使用parted，但我一直无法使用xfs_grow调整文件系统。 分割的工具不支持xfs。
