aws和ufile掛載數據盤EBS

aws的話掛載的ebs須要格式化，參考：
https://docs.aws.amazon.com/zh_cn/AWSEC2/latest/UserGuide/ebs-using-volumes.html

[root@oride-dr-algo1 .ssh]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
nvme0n1 259:1 0 30G 0 disk
└─nvme0n1p1 259:2 0 30G 0 part /
nvme1n1 259:0 0 500G 0 disk

file -s /dev/nvme1n1
mkfs -t xfs /dev/nvme1n1
mount /dev/nvme1n1 /data
#添加開機啓動，否則啓動後掛載會丟失
cp /etc/fstab /etc/fstab.orig
查看設備的uuid
blkid或ls -l  /dev/disk/by-uuid/
/dev/nvme1n1: UUID="d75ddf68-d300-4f66-a484-f76a53868e38" TYPE="xfs"

vim /etc/fstab
UUID=5d95cbda-ece5-42a7-aa57-15070030a904 /data xfs defaults,nofail 0 2

要檢查條目是否有效:
umount /data #強制：　umount -f /data
mount -a

也可直接reboot測試

 

ufile:

ufile擴容系統盤直接在控制檯上操做,擴容系統盤需從新mount

https://docs.ucloud.cn/compute/uhost/guide/disk

fdisk -l

df -ihT

centos7:

umount /dev/vdb
xfs_repair /dev/vdb
mount /dev/vdb /data
xfs_growfs /data

#新加數據盤的話需先格式化再掛載

mkfs.xfs /dev/vdb

mount /dev/vdb /data

 

centos6:

umount /dev/vdb
e2fsck -f  /dev/vdb

resize2fs  /dev/vdb
mount /dev/vdb /data

 

注: 遇到umount busy的狀況

能夠 fuser -m /data看下佔用/data的程序，關掉這些程序再卸載
