正在使用的LINUX系统,增加了空间,需要挂载至系统
--------查询需要挂载的设备名--------
fdisk -l
Disk /dev/sdb: 2396.0 GB, 2395996160000 bytes
255 heads, 63 sectors/track, 291296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x00000000
Disk /dev/sdc: 2396.0 GB, 2395996160000 bytes
255 heads, 63 sectors/track, 291296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

-----创建PV----
pvcreate /dev/sdb
pvcreate /dev/sdc
---创建vg-----
vgcreate VolGroup_data /dev/sdb /dev/sdc
mkdir /data
cd
----创建lv-------
lvcreate -l 100%FREE -n lv_data VolGroup_data
----格式化----
mkfs -t ext4 /dev/VolGroup_data/lv_data
-----挂载----
mount /dev/VolGroup_data/lv_data /data/
-------增加到启动挂载-------
vi /etc/fstab
可以按照uuid挂载,也可以按照路径,比如:
uuid可以通过lvdisplay查询。
UUID=22d59ff0-1646-4e28-af50-e7281286934c / ext4 defaults 1 1
/dev/mapper/VolGroup_data-lv_data /data ext4 defaults 0 0
