Linux下的硬盘信息查看

1.fdisk -l 查看硬盘/dev/hd0 -----------IDE设备老式硬盘,并口硬盘sda 串口硬盘  sata s  串口d硬盘 a第一块/dev/sro  /dev/cdrom 光驱/dev/mapper  虚拟设备blkid  识别系统可以用的设备blkid<=cat/proc/partitions <=fdisk -l  小于等于

df -h   查看设备大小以2ⁿ计数，结果更加准确。1G=1024M

df -H  查看设备大小 10ⁿ计数,查询结果d大于 “df -h”所查询的.1G=1000M

root@foundation42 ~]# blkid /dev/sda1: UUID="c0764391-f54b-49d1-a60a-9f85cb90bbbd" TYPE="xfs" /dev/sda2: UUID="32975f91-edb0-4ce4-a234-1286dd2b52d0" TYPE="swap" /dev/sda3: UUID="804af6c8-6aae-42c6-bd7e-57f6d1946aae" TYPE="xfs" /dev/loop0: UUID="2014-05-07-03-58-46-00" LABEL="RHEL-7.0 Server.x86_64" TYPE="iso9660" PTTYPE="dos" /dev/loop1: UUID="2015-10-30-11-11-49-00" LABEL="RHEL-7.2 Server.x86_64" TYPE="iso9660" PTTYPE="dos" /dev/sdb1: UUID="44ED-5693" TYPE="vfat" [root@foundation42 ~]# fuser -vm /dev/sdb1 USER PID ACCESS COMMAND /dev/sdb1: root kernel mount /run/media/kiosk/44ED-5693

2.设备的挂载

[root@foundation42 ~]# umount /dev/sdb1 umount: /mnt: target is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) [root@foundation42 ~]# fuser -kvm /dev/sdb1 USER PID ACCESS COMMAND /dev/sdb1: root kernel mount /mnt kiosk 30926 ..c.. bash [root@foundation42 ~]# ls /mnt ?? homework unit12 ???? picture unit13 ????? rhel-server-7.0-x86_64-dvd.iso unit14 4.21 rhel-server-7.2-x86_64-dvd.iso unit15 422 System Volume Information [root@foundation42 ~]# umount /dev/sdb1 [root@foundation42 ~]# ls /mnt test

umount /dev/sdb1  解除挂载mount /dev/sdb1   挂载
