一 摘要

本文主要介绍proxmox 宿主机添加硬盘，最早是先手工格式化硬盘，手工挂载硬盘，然后再到proxmox web 上添加，其实可以直接在proxmox web 上直接完成以上操作。

二 环境信息

root@gpu002:/etc/apt# cat /etc/debian_version 10.9 root@gpu002:/etc/apt# uname -a Linux gpu002 5.4.106-1-pve #1 SMP PVE 5.4.106-1 (Fri, 19 Mar 2021 11:08:47 +0100) x86_64 GNU/Linux root@gpu002:/etc/apt# 

三 实施

（一）添加小于两T 的硬盘

3.1.1

root@testgpu:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 223.1G 0 disk ├─sda1 8:1 0 1007K 0 part ├─sda2 8:2 0 512M 0 part /boot/efi └─sda3 8:3 0 222.6G 0 part ├─pve-swap 253:0 0 8G 0 lvm [SWAP] ├─pve-root 253:1 0 55.5G 0 lvm / ├─pve-data_tmeta 253:2 0 1.4G 0 lvm │ └─pve-data 253:4 0 140.2G 0 lvm └─pve-data_tdata 253:3 0 140.2G 0 lvm └─pve-data 253:4 0 140.2G 0 lvm sdb 8:16 0 1.8T 0 disk root@testgpu:~# 

3.1.2

root@testgpu:~# fdisk -u /dev/sdb Welcome to fdisk (util-linux 2.33.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): p Disk /dev/sdb: 1.8 TiB, 00 bytes,  sectors Disk model: INSPUR Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal):  bytes /  bytes Disklabel type: gpt Disk identifier: 90A08D26-423A-4ED3-9F6E-B768CF08EFE0 Command (m for help): n Partition number (1-128, default 1): First sector (34-, default 2048): Last sector, +/-sectors or +/-size{

Calling ioctl() to re-read partition table. Syncing disks. root@testgpu:~# 

mkfs -t xfs /dev/sdb1使用xfs 还是ext4 等，自己定。一个系统最好文件系统格式一致。

root@testgpu:~# mkfs -t xfs /dev/sdb1 meta-data=/dev/sdb1 isize=512 agcount=32, agsize= blks = sectsz=4096 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=0 = reflink=0 data = bsize=4096 blocks=, imaxpct=5 = sunit=64 swidth=64 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 root@testgpu:~# 

 root@testgpu:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 223.1G 0 disk ├─sda1 8:1 0 1007K 0 part ├─sda2 8:2 0 512M 0 part /boot/efi └─sda3 8:3 0 222.6G 0 part ├─pve-swap 253:0 0 8G 0 lvm [SWAP] ├─pve-root 253:1 0 55.5G 0 lvm / ├─pve-data_tmeta 253:2 0 1.4G 0 lvm │ └─pve-data 253:4 0 140.2G 0 lvm └─pve-data_tdata 253:3 0 140.2G 0 lvm └─pve-data 253:4 0 140.2G 0 lvm sdb 8:16 0 1.8T 0 disk └─sdb1 8:17 0 1.8T 0 part root@testgpu:~# mkdir /mnt/sdb1 root@testgpu:~# echo `blkid /dev/sdb1 | awk '{print $2}' | sed 's/\"//g'` /mnt/sdb1 xfs defaults 0 0 >> /etc/fstab 

3.1.3

重启系统

然后去proxmox 管理端操作。

（二）添加大于2T 的硬盘

3.2.1 安装 parted e2fsprogs

root@gpu002:/etc/apt# apt-get install parted root@gpu002:/etc/apt# apt-get install e2fsprogs 

3.2.2 检查是否包含未挂载数据盘

root@gpu002:/etc/apt# fdisk -l Disk /dev/sdb: 3.7 TiB, 12 bytes,  sectors Disk model: INSPUR Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal):  bytes /  bytes Disk /dev/sda: 223.1 GiB, 6 bytes,  sectors Disk model: INSPUR Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal):  bytes /  bytes Disklabel type: gpt Disk identifier: 8AA43297-648A-4644-99EE-09FE36CD8685 Device Start End Sectors Size Type /dev/sda1 34 2047 2014 1007K BIOS boot /dev/sda2 2048   512M EFI System /dev/sda3    222.6G Linux LVM Partition 1 does not start on physical sector boundary. Disk /dev/mapper/pve-swap: 8 GiB,  bytes,  sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal):  bytes /  bytes Disk /dev/mapper/pve-root: 55.5 GiB,  bytes,  sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal):  bytes /  bytes 

3.2.3 使用Parted工具为数据盘进行分区

命令说明

parted /dev/vdb //运行以下命令开始分区 mklabel gpt //运行以下命令，将默认的MBR分区格式转为GPT分区格式 mkpart primary 1 100% //运行以下命令，划分一个主分区，并设置分区的开始位置和结束位置 align-check optimal 1 //运行以下命令，检查分区是否对齐。 该命令输出结果 1 aligned 

截图说明

我的操作记录

root@gpu002:/etc/apt# parted /dev/sdb GNU Parted 3.2 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mklabel gpt Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue? Yes/No? yes (parted) mkpart primary 1 100% (parted) align-check optimal 1 1 aligned (parted) print Model: AVAGO INSPUR (scsi) Disk /dev/sdb: 4000GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 4000GB 4000GB primary (parted) quit Information: You may need to update /etc/fstab. root@gpu002:/etc/apt# 

3.2.4 重读分区表

 root@gpu002:/etc/apt# partprobe root@gpu002:/etc/apt# 

3.2.5 创建一个文件系统

root@gpu002:/etc/apt# mkfs -t xfs /dev/sdb1 meta-data=/dev/sdb1 isize=512 agcount=32, agsize= blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=0 = reflink=0 data = bsize=4096 blocks=, imaxpct=5 = sunit=64 swidth=64 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 root@gpu002:/etc/apt# 

root@gpu002:/etc/apt# df -h Filesystem Size Used Avail Use% Mounted on udev 126G 0 126G 0% /dev tmpfs 26G 74M 26G 1% /run /dev/mapper/pve-root 55G 20G 33G 37% / tmpfs 126G 34M 126G 1% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 126G 0 126G 0% /sys/fs/cgroup /dev/sda2 511M 312K 511M 1% /boot/efi /dev/fuse 30M 16K 30M 1% /etc/pve tmpfs 26G 0 26G 0% /run/user/0 root@gpu002:/etc/apt# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 223.1G 0 disk ├─sda1 8:1 0 1007K 0 part ├─sda2 8:2 0 512M 0 part /boot/efi └─sda3 8:3 0 222.6G 0 part ├─pve-swap 253:0 0 8G 0 lvm [SWAP] ├─pve-root 253:1 0 55.5G 0 lvm / ├─pve-data_tmeta 253:2 0 1.4G 0 lvm │ └─pve-data 253:4 0 140.2G 0 lvm └─pve-data_tdata 253:3 0 140.2G 0 lvm └─pve-data 253:4 0 140.2G 0 lvm sdb 8:16 0 3.7T 0 disk └─sdb1 8:17 0 3.7T 0 part 

3.3.6 挂载到/mnt/sdb1

root@gpu002:/mnt# mkdir /mnt/sdb1 root@gpu002:/mnt# cp /etc/fstab /etc/fstab.bak.orig root@gpu002:/mnt# echo `blkid /dev/sdb1 | awk '{print $2}' | sed 's/\"//g'` /mnt/sdb1 xfs defaults 0 0 >> /etc/fstab root@gpu002:/mnt# root@gpu002:/mnt# reboot 

重启了系统后 到proxmox 管理端操作 参考3.1.3

（三）使用web 系统添加硬盘（推荐）
