rocky linux:为新磁盘做分区/格式化/挂载(Rocky Linux 9.1)
一，查看所有磁盘
查看磁盘的分区
[root@blog ~]# fdisk -l
Disk /dev/vda: 50 GiB, 53687091200 bytes, 104857600 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: gpt
Disk identifier: CDEEAA24-BF4D-4FEA-965A-75143EC1F765
Device Start End Sectors Size Type
/dev/vda1 2048 4095 2048 1M BIOS boot
/dev/vda2 4096 208895 204800 100M EFI System
/dev/vda3 208896 104857566 104648671 49.9G Linux filesystem
Disk /dev/vdb: 100 GiB, 107374182400 bytes, 209715200 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查看已挂载的分区,可以看到/dev/vdb未挂载
[root@blog ~]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 4.0M 0 4.0M 0% /dev
tmpfs 3.7G 0 3.7G 0% /dev/shm
tmpfs 1.5G 544K 1.5G 1% /run
/dev/vda3 50G 3.1G 47G 7% /
/dev/vda2 100M 7.0M 93M 7% /boot/efi
tmpfs 50M 0 50M 0% /usr/local/aegis/cgroup
tmpfs 742M 0 742M 0% /run/user/0二，分区:
[root@blog ~]# parted /dev/vdb
GNU Parted 3.5
Using /dev/vdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) help
align-check TYPE N check partition N for TYPE(min|opt) alignment
help [COMMAND] print general help, or help on COMMAND
mklabel,mktable LABEL-TYPE create a new disklabel (partition table)
mkpart PART-TYPE [FS-TYPE] START END make a partition
name NUMBER NAME name partition NUMBER as NAME
print [devices|free|list,all] display the partition table, or available devices, or free space, or all found partitions
quit exit program
rescue START END rescue a lost partition near START and END
resizepart NUMBER END resize partition NUMBER
rm NUMBER delete partition NUMBER
select DEVICE choose the device to edit
disk_set FLAG STATE change the FLAG on selected device
disk_toggle [FLAG] toggle the state of FLAG on selected device
set NUMBER FLAG STATE change the FLAG on partition NUMBER
toggle [NUMBER [FLAG]] toggle the state of FLAG on partition NUMBER
type NUMBER TYPE-ID or TYPE-UUID type set TYPE-ID or TYPE-UUID of partition NUMBER
unit UNIT set the default unit to UNIT
version display the version number and copyright information of GNU Parted
(parted) print
Error: /dev/vdb: unrecognised disk label

Disk /dev/vdb: 107GB
Sector size (logical/physical): 512B/512B

三，格式化
[root@blog ~]# mkfs.ext4 /dev/vdb1
mke2fs 1.46.5 (30-Dec-2021)
Creating filesystem with 26213888 4k blocks and 6553600 inodes
Filesystem UUID: d25c9fa0-6123-45d2-bbeb-adf1c21ee6c6
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424, 20480000, 23887872
Allocating group tables: done
Writing inode tables: done
Creating journal (131072 blocks): done
Writing superblocks and filesystem accounting information: done四，挂载
[root@blog ~]# mount /dev/vdb1 /web
[root@blog ~]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 4.0M 0 4.0M 0% /dev
tmpfs 3.7G 0 3.7G 0% /dev/shm
tmpfs 1.5G 544K 1.5G 1% /run
/dev/vda3 50G 3.1G 47G 7% /
/dev/vda2 100M 7.0M 93M 7% /boot/efi
tmpfs 50M 0 50M 0% /usr/local/aegis/cgroup
tmpfs 742M 0 742M 0% /run/user/0
/dev/vdb1 98G 24K 93G 1% /web五，编辑fstab配置文件，实现启动时自动挂载:
[root@blog ~]# blkid
/dev/vdb1: UUID="d25c9fa0-6123-45d2-bbeb-adf1c21ee6c6" TYPE="ext4" PARTLABEL="primary" PARTUUID="980c51af-a08b-4f3e-932a-2f0b6ced4a46"
/dev/vda2: SEC_TYPE="msdos" UUID="54F8-66C8" TYPE="vfat" PARTUUID="a5b87af5-0a78-4a81-a97e-79ff22a64bc9"
/dev/vda3: LABEL="root" UUID="87d48954-0eea-4e64-8c6e-27a537d26032" TYPE="xfs" PARTUUID="78a160b6-9409-479c-91ce-10f0989470b6"
/dev/vda1: PARTUUID="dfead5b8-c2c1-41f6-b3d4-0fdc094b74f4”
[root@blog ~]# vi /etc/fstab
增加一行:
UUID=d25c9fa0-6123-45d2-bbeb-adf1c21ee6c6 /web ext4 defaults 0 2六，查看linux的版本:
[root@blog ~]# cat /etc/redhat-release
