Today I'll show you how to mount and unmount AWS EBS disks. The content of the article is good. Now I would like to share it with you. Friends who feel in need can understand it. I hope it will be helpful to you. Let's read it along with the editor's ideas.

1. AWS EBS mount

1. View the volumes that have been connected

[root@worker-oss centos] # lsblk

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

Xvda 202:0 0 20G 0 disk

└─ xvda1 202:1 0 20G 0 part /

Xvdf 202:80 0 30G 0 disk / fastdfs

Xvdg 202:96 0 15G 0 disk

2. Format the volume you just loaded. For example, xvdg is a newly added volume.

[root@worker-oss centos] # sudo mkfs-t xfs / dev/xvdg

Meta-data=/dev/xvdg isize=512 agcount=4, agsize=983040 blks

= sectsz=512 attr=2, projid32bit=1

= crc=1 finobt=0, sparse=0

Data = bsize=4096 blocks=3932160, imaxpct=25

= sunit=0 swidth=0 blks

Naming = version 2 bsize=4096 ascii-ci=0 ftype=1

Log = internal log bsize=4096 blocks=2560, version=2

= sectsz=512 sunit=0 blks, lazy-count=1

Realtime = none extsz=4096 blocks=0, rtextents=0

3. Check the UUID of the device xvdg

[root@worker-oss centos] # ls-al / dev/disk/by-uuid/

Total dosage 0

Drwxr-xr-x. 3 root root 60 July 17 14:57..

Lrwxrwxrwx. 1 root root 10 July 20 01:39 0cf71957-56a6-4302-873e-1998f81aac5b->.. / xvdg

Lrwxrwxrwx. 1 root root 11 July 17 14:57 5f1871e2-c19c-4f86-8d6c-04d5fda71a0a->.. /.. / xvda1

Lrwxrwxrwx. 1 root root 10 July 18 10:51 9a011466-05e8-475d-ac40-745309acf40a->.. / xvdf

4. Create a directory to be mounted

[root@worker-oss centos] # mkdir / db

5. Mount xvdg to the / db directory

[root@worker-oss centos] # cp / etc/fstab / etc/fstab.bak

[root@worker-oss centos] # vim / etc/fstab

UUID=5f1871e2-c19c-4f86-8d6c-04d5fda71a0a / xfs defaults 0 0

UUID=9a011466-05e8-475d-ac40-745309acf40a / fastdfs xfs defaults,nofail 0 2

UUID=0cf71957-56a6-4302-873e-1998f81aac5b / db xfs defaults,nofail 02

6. Mount the volume

[root@worker-oss db] # sudo mount-a

6. View the mounted directory

[root@worker-oss centos] # cd / db/

[root@worker-oss db] # ls-al

Unmount the AWS EBS volume

1. Unmount volume fastdfs

Umount-d / dev/xvdf

2. Delete the uuid in / etc/fstab

Vim / etc/fstab/

# UUID=9a011466-05e8-475d-ac40-745309acf40a / fastdfs xfs defaults,nofail 0 2
