虚拟机磁盘扩容(适合所有lvm类型)
这里以convirt为例!
1.物理机新建磁盘
[root@sz-145-centos24 ~]# cd /data/convirt/vm_disks [root@sz-145-centos24 vm_disks]# qemu-img create -f raw sz-145-centos177-2.xm 10G
2.convirt平台修改虚拟机配置
关机后修改
修改完成后重启虚拟机,生效配置。
3.登陆虚拟机配置lvm
1、查看是否有新增的磁盘(这里为/dev/sdb)
[root@sz-145-centos177 ~]# fdisk -l | grep Disk Disk /dev/sda: 125.8 GB, 125829120512 bytes Disk identifier: 0x0000ec73 Disk /dev/sdb: 10.7 GB, 10737418240 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg_templet-lv_root: 116.9 GB, 116912029696 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg_templet-lv_swap: 8388 MB, 8388608000 bytes Disk identifier: 0x00000000
2、创建pv
[root@sz-145-centos177 ~]# pvcreate /dev/sdb Physical volume "/dev/sdb" successfully created
3、查看vg name
[root@sz-145-centos177 ~]# vgdisplay --- Volume group --- VG Name vg_templet System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 3 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 116.70 GiB PE Size 4.00 MiB Total PE 29874 Alloc PE / Size 29874 / 116.70 GiB Free PE / Size 0 / 0 VG UUID kC3k3E-kTBv-isC7-7c7F-VhJu-YBHH-JinGkb
4、扩容vg
[root@sz-145-centos177 ~]# vgextend vg_templet /dev/sdb Volume group "vg_templet" successfully extended
5、扩容lv
[root@sz-145-centos177 ~]# num=`vgdisplay |grep "Free" |awk '{print $5}'` [root@sz-145-centos177 ~]# lvresize -l +$num /dev/vg_templet/lv_root Size of logical volume vg_templet/lv_root changed from 108.88 GiB (27874 extents) to 118.88 GiB (30433 extents). Logical volume lv_root successfully resized.
6、LV分区重设大小
[root@sz-145-centos177 ~]# resize2fs /dev/mapper/vg_templet-lv_root resize2fs 1.41.12 (17-May-2010) Filesystem at /dev/mapper/vg_templet-lv_root is mounted on /; on-line resizing required old desc_blocks = 7, new_desc_blocks = 8 Performing an on-line resize of /dev/mapper/vg_templet-lv_root to 31163392 (4k) blocks. The filesystem on /dev/mapper/vg_templet-lv_root is now 31163392 blocks long.
7.检查扩容后磁盘情况
[root@sz-145-centos177 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_templet-lv_root 117G 2.9G 109G 3% / tmpfs 1.9G 0 1.9G 0% /dev/shm /dev/sda1 477M 39M 413M 9% /boot
