一 XFS文件系統(tǒng)簡(jiǎn)介
XFS是高性能文件系統(tǒng)童芹，SGI為他們的IRIX平臺(tái)而設(shè)計(jì)。自從2001年移植到Linux內(nèi)核上鲤拿，由于它的高性能假褪，XFS成為了許多企業(yè)級(jí)系統(tǒng)的首選，特別是有大量數(shù)據(jù)近顷，需要結(jié)構(gòu)化伸縮性和穩(wěn)定性的生音。例如，RHEL/CentOS 7 和Oracle Linux將XFS作為默認(rèn)文件系統(tǒng)窒升，SUSE/openSUSE已經(jīng)為XFS做了長(zhǎng)期支持缀遍。
XFS有許多獨(dú)特的性能提升功能使他從眾多文件系統(tǒng)中脫穎而出，像可伸縮/并行 IO饱须，元數(shù)據(jù)日志域醇，熱碎片整理，IO 暫停/恢復(fù)蓉媳，延遲分配等譬挚。
二 安裝XFS系統(tǒng)工具集
Debian, Ubuntu , Linux Mint系統(tǒng)：
$ sudo apt-get install xfsprogs
Fedora, CentOS, RHEL系統(tǒng):
$ sudo yum install xfsprogs
其他版本Linux:
$ sudo pacman -S xfsprogs

然后一路默認(rèn) - 輸入w保存
四 格式化分區(qū)
1.格式化分區(qū)為XFS，使用mkfs.xfs命令号杠。如果已有其他文件系統(tǒng)創(chuàng)建在此分區(qū)蚪腋，必須加上"-f"參數(shù)來(lái)覆蓋它。
sudo mkfs.xfs -f /dev/sdb1
2.格式化后分區(qū)來(lái)掛載姨蟋。假設(shè)/mnt是XFS本地掛載點(diǎn)屉凯。使用下述命令掛載
sudo mount -t xfs /dev/sdb1 /mnt
3.驗(yàn)證XFS掛載是否成功：
df -Th /storage
4.如果你想要啟動(dòng)時(shí)自動(dòng)掛載XFS分區(qū)在/storage上，加入下列行到/etc/fstab：
/dev/sdb1 /storage xfs defaults 0 0
