如何查看Linux中的文件系统状态?
您可以使用以下命令查看Linux中文件系统的当前状态。
挂载命令mount
要显示有关已挂载文件系统的信息,请执行:
$ mount | column -t
输出示例:
/dev/sda5 on / type ext3 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) none on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) none on /dev type devtmpfs (rw,mode=0755) none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) none on /dev/shm type tmpfs (rw,nosuid,nodev) none on /var/run type tmpfs (rw,nosuid,mode=0755) none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) gvfs-fuse-daemon on /home/Hyman/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=Hyman) nas01:/mp3 on /nfs type nfs (rw,addr=192.168.3.1) none on /proc/fs/vmblock/mountPoint type vmblock (rw)
df命令
要了解文件系统磁盘空间的使用情况,请执行:
$ df $ df -H
输出示例:
Filesystem Size Used Avail Use% Mounted on /dev/sda5 477G 167G 285G 37% / none 4.2G 402k 4.2G 1% /dev none 4.2G 2.1M 4.2G 1% /dev/shm none 4.2G 312k 4.2G 1% /var/run none 4.2G 0 4.2G 0% /var/lock none 4.2G 0 4.2G 0% /lib/init/rw nas01:/mp3 6.0T 127G 5.8T 3% /nfs
du命令
使用du命令估计文件空间使用量,执行:
$ du $ du /home $ du -ch /home
列出分区表
执行fdisk命令,如下所示(必须以root身份运行):
# fdisk -l # fdisk -l /dev/sda
输出示例:
Disk /dev/sda: 500.1 GB, 500107862015 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xf0000000 Device Boot Start End Blocks Id System /dev/sda1 * 1 1992 15998976 82 Linux swap / Solaris /dev/sda2 1993 60802 472384513 5 Extended /dev/sda5 1993 60802 472384512 83 Linux
