linux下如何删除磁盘分区
分区示例：比如分/dev/sda 硬盘
#: fdisk /dev/sda
The number of cylinders for this disk is set to 19457.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): m #帮助,输入M
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition 删除一个分区
l list known partition types
m print this menu
n add a new partition 创建一个新的分区
o create a new empty DOS partition table
p print the partition table 打印分区表
q quit without saving changes 退出不保存
s create a new empty Sun disklabel
t change a partition\'s system id 改变分区类型
u change display/entry units 改变显示/输入的单位
v verify the partition table 验证这个分区表
w write table to disk and exit 保存退出
x extra functionality (experts only)
Command (m for help): d #删除分区

阿里云linux服务器硬盘满了怎么清理
要对Linux使用比较熟悉的人操作这个清理比较好，查看是哪些没用的东西占据了硬盘，查出来删掉就行了。如果对Linux使用不熟悉，硬盘满了建议还是另外购买硬盘容量吧。希望回答能对你有帮助！
1.linux服务器磁盘满了，怎么删除
在日常使用过程中，可能会经常遇到Linux服务器磁盘空间满的问题。
一、遇到磁盘空间不足的报错时候，首先使用df -h查看磁盘空间使用情况，如下图所示
二、进入目录/home/zhang，查找磁盘空间中的大文件，使用命令du -sh *查找占用空间大的目录，通过逐层定位，最后会找到具体的文件。
三、第二步的命令虽然能看到了，但是文件太多不好找，使用du -h --max-depth=1命令查找空间占用大的文件。
linux虚拟机卸载新硬盘的方法
装载：
1、启动vm，选择vm-Settings,按向导添加一块SCSI磁盘。进入Linux系统。
2、 fdisk -l 会看到有一块新的设置,如果你先前有一块硬盘(sda1, sda3...),新加的这块应该是(/dev/sdb)。
[root@localhost ~]# fdisk -l
Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda3 14 1044 8281507+ 83 Linux
Disk /dev/sdb: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table
3、分区：
[root@localhost ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 1044.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1044, default 1):

Last cylinder or +size or +sizeM or +sizeK (1-1044, default 1044):

The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
[root@localhost ~]# fdisk -l
Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda3 14 1044 8281507+ 83 Linux
Disk /dev/sdb: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 1044 8385898+ 83 Linux
4、格式化：
[root@localhost ~]# mkfs -t ext3 /dev/sdb1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
1048576 inodes, 2096474 blocks
104823 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=2147483648
64 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 31 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
5、装载：
[root@localhost ~]# mount /dev/sdb1 /u01/app/oracle
[root@localhost ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
6.7G 5.8G 576M 92% /
/dev/sda1 99M 12M 82M 13% /boot
tmpfs 233M 0 233M 0% /dev/shm
/dev/sdb1 7.9G 147M 7.4G 2% /u01/app/oracle
6、编辑fstab文件（不然重启电脑后系统将不会保存之前的挂载操作）：
[root@localhost ~]# vi /etc/fstab
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/sdc1 /u03 ext3 defaults 1 1
/dev/sdb1 /u01/app/oracle ext3 defaults 1 1
# Beginning of the block added by the VMware software
.host:/ /mnt/hgfs vmhgfs defaults,ttl=5 0 0
# End of the block added by the VMware software
卸载：
[root@localhost ~]# umount /dev/sdb1
[root@localhost ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
6.7G 5.8G 576M 92% /
/dev/sda1 99M 12M 82M 13% /boot
tmpfs 233M 0 233M 0% /dev/shm
linux新添加的硬盘可以删除吗
备份了数据就可以删啊，当然也要看具体配置，比如有没有挂载该硬盘到重要路径，没弄清楚就删可能导致系统无法正常启动。
