1.使用fdisk对/dev/nvme0n1剩余空间进行分区
[root@192 ~]
Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): n
Partition type
p primary (2 primary, 0 extended, 2 free)
e extended (container for logical partitions)
Select (default p):
Using default response p.
Partition number (3,4, default 3): 3
First sector (78301184-83886079, default 78301184):
Last sector, +sectors or +size{K,M,G,T,P} (78301184-83886079, default 83886079):
Created a new partition 3 of type 'Linux' and of size 2.7 GiB.
Command (m for help): p
Disk /dev/nvme0n1: 40 GiB, 42949672960 bytes, 83886080 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x38d65830
Device Boot Start End Sectors Size Id Type
/dev/nvme0n1p1 * 2048 2099199 2097152 1G 83 Linux
/dev/nvme0n1p2 2099200 78301183 76201984 36.3G 8e Linux LVM
/dev/nvme0n1p3 78301184 83886079 5584896 2.7G 83 Linux
2.新添加一块儿磁盘使用gdisk，设置gpt分区表，新建分区
[root@192 ~]
GPT fdisk (gdisk) version 1.0.3
Partition table scan:
MBR: not present
BSD: not present
APM: not present
GPT: not present
Creating new GPT entries.
Command (? for help): o
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y
Command (? for help): n
Partition number (1-128, default 1):
First sector (34-2097118, default = 2048) or {+-}size{KMGTP}:
Last sector (2048-2097118, default = 2097118) or {+-}size{KMGTP}:
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): 8e00
Changed type of partition to 'Linux LVM'
Command (? for help): p
Disk /dev/nvme0n2: 2097152 sectors, 1024.0 MiB
Model: VMware Virtual NVMe Disk
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 6555EB8D-7C16-4D0F-A0BC-35B51F7535F1
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 2097118
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)
Number Start (sector) End (sector) Size Code Name
1 2048 2097118 1023.0 MiB 8E00 Linux LVM
3.使用parted对新添加的磁盘添加分区(交互式)
(parted) mkpart gzw1 200M 500M
(parted) p
Model: NVMe Device (nvme)
Disk /dev/nvme0n2: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 200MB 500MB 300MB gzw1
4.使用parted对/dev/nvme0n1新增分区(命令式)
[root@192 ~]
GNU Parted 3.2
Using /dev/nvme0n2
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) p
Error: /dev/nvme0n2: unrecognised disk label
Model: NVMe Device (nvme)
Disk /dev/nvme0n2: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags:
(parted) mklabel gpt
(parted) mkpart
Partition name? []? gzw1
File system type? [ext2]? ext4
Start? 0
End? 1074MB
Warning: The resulting partition is not properly aligned for best performance: 34s % 2048s != 0s
Ignore/Cancel? Ignore
(parted) p
Model: NVMe Device (nvme)
Disk /dev/nvme0n2: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 17.4kB 1074MB 1074MB ext4 gzw1
5.挑选任一分区，进行格式化挂载(临时挂载)
[root@192 ~]
meta-data=/dev/nvme0n2p1 isize=512 agcount=4, agsize=65534 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=1, sparse=1, rmapbt=0
= reflink=1
data = bsize=4096 blocks=262135, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0, ftype=1
log =internal log bsize=4096 blocks=1566, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
6.挑选另一分区，进行格式化挂载(永久挂载)
[root@server /]
