esxi报错There is no more space for virtual disk--逻辑卷缩减！

Posted 2020-08-04

来自 localhost.localdomain 的消息: There is no more space for virtual disk ftp-000001.vmdk. You might be able to continue this session by freeing disk space on the elevant volume, and clicking _Retry. Click Cancel to terminate this session. 

问题：磁盘空间分配不合理。

解决方式，合理分配磁盘空间。磁盘做的逻辑卷，温习一下。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

温习下逻辑卷：

1、物理卷创建

[[email protected] ~]# vg

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3、逻辑卷创建

[[email protected] ~]# lvcreate -L 2G -n renzhiyuan_lv renzhiyuan_vg

  Logical volume "renzhiyuan_lv" created

[[email protected] ~]# lvdisplay 

  --- Logical volume ---

  LV Path                /dev/renzhiyuan_vg/renzhiyuan_lv

  LV Name                renzhiyuan_lv

[[email protected] ~]#

[[email protected] ~]# lv

lvchange     lvdisplay    lvmchange    lvmdump      lvmsar       lvrename     lvscan       

lvconvert    lvextend     lvmconf      lvmetad      lvreduce     lvresize     

lvcreate     lvm          lvmdiskscan  lvmsadc      lvremove     lvs          

[[email protected] ~]# lv

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

4、格式化逻辑卷

[[email protected] ~]# mkfs.ext4 /dev/renzhiyuan_vg/renzhiyuan_lv 

mke2fs 1.41.12 (17-May-2010)

文件系统标签=

操作系统:Linux

块大小=4096 (log=2)

分块大小=4096 (log=2)

Stride=0 blocks, Stripe width=0 blocks

131072 inodes, 524288 blocks

26214 blocks (5.00%) reserved for the super user

第一个数据块=0

Maximum filesystem blocks=536870912

16 block groups

32768 blocks per group, 32768 fragments per group

8192 inodes per group

Superblock backups stored on blocks: 

32768, 98304, 163840, 229376, 294912

正在写入inode表: 完成                            

Creating journal (16384 blocks): 完成

Writing superblocks and filesystem accounting information: 完成

This filesystem will be automatically checked every 36 mounts or

180 days, whichever comes first.  Use tune2fs -c or -i to override.

5、挂载逻辑卷

[[email protected] ~]# mount /dev/renzhiyuan_vg/renzhiyuan_lv /opt/renzhiyuan/

[[email protected] ~]# df -TH

Filesystem           Type   Size  Used Avail Use% Mounted on

/dev/mapper/vg_node6-lv_root

                     ext4    19G  1.2G   17G   7% /

tmpfs                tmpfs  515M     0  515M   0% /dev/shm

/dev/sda1            ext4   500M   27M  448M   6% /boot

/dev/mapper/renzhiyuan_vg-renzhiyuan_lv

                     ext4   2.1G  3.2M  2.0G   1% /opt/renzhiyuan

[[email protected] ~]#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

6、缩减逻辑卷

6.1）卸载

[[email protected] ~]# umount  /opt/renzhiyuan/

[[email protected] ~]# df -TH

Filesystem           Type   Size  Used Avail Use% Mounted on

/dev/mapper/vg_node6-lv_root

                     ext4    19G  1.2G   17G   7% /

tmpfs                tmpfs  515M     0  515M   0% /dev/shm

/dev/sda1            ext4   500M   27M  448M   6% /boot

[[email protected] ~]#

6.2）强制对文件系统进行检查

[[email protected] ~]# e2fsck -f /dev/renzhiyuan_vg/renzhiyuan_lv 

e2fsck 1.41.12 (17-May-2010)

第一步: 检查inode,块,和大小

第二步: 检查目录结构

第3步: 检查目录连接性

Pass 4: Checking reference counts

第5步: 检查簇概要信息

/dev/renzhiyuan_vg/renzhiyuan_lv: 11/131072 files (0.0% non-contiguous), 25388/524288 blocks

[[email protected] ~]#

6.3）对文件系统进行缩减

[[email protected] ~]# resize2fs /dev/renzhiyuan_vg/renzhiyuan_lv 1G

resize2fs 1.41.12 (17-May-2010)

Resizing the filesystem on /dev/renzhiyuan_vg/renzhiyuan_lv to 262144 (4k) blocks.

The filesystem on /dev/renzhiyuan_vg/renzhiyuan_lv is now 262144 blocks long.

[[email protected] ~]#

6.4）对逻辑卷进行缩减

[[email protected] ~]# lvreduce -L 1G /dev/renzhiyuan_vg/renzhiyuan_lv 

  WARNING: Reducing active logical volume to 1.00 GiB

  THIS MAY DESTROY YOUR DATA (filesystem etc.)

Do you really want to reduce renzhiyuan_lv? [y/n]: y

  Size of logical volume renzhiyuan_vg/renzhiyuan_lv changed from 2.00 GiB (512 extents) to 1.00 GiB (256 extents).

  Logical volume renzhiyuan_lv successfully resized

[[email protected] ~]#

[[email protected] ~]# lvdisplay 

  --- Logical volume ---

  LV Path                /dev/renzhiyuan_vg/renzhiyuan_lv

  LV Name                renzhiyuan_lv

  VG Name                renzhiyuan_vg

  LV UUID                nW3HXj-CwOI-8lVo-B3Zo-nVKd-fNa6-1tUy3m

  LV Write Access        read/write

  LV Creation host, time node6, 2016-08-26 09:33:50 +0800

  LV Status              available

  # open                 0

  LV Size                1.00 GiB

  Current LE             256

  Segments               2

  Allocation             inherit

  Read ahead sectors     auto

  - currently set to     256

  Block device           253:2

6.5）挂载验证

[[email protected] ~]# mount /dev/renzhiyuan_vg/renzhiyuan_lv  /opt/renzhiyuan/

[[email protected] ~]# df -TH

Filesystem           Type   Size  Used Avail Use% Mounted on

/dev/mapper/vg_node6-lv_root

                     ext4    19G  1.2G   17G   7% /

tmpfs                tmpfs  515M     0  515M   0% /dev/shm

/dev/sda1            ext4   500M   27M  448M   6% /boot

/dev/mapper/renzhiyuan_vg-renzhiyuan_lv

                     ext4   990M  2.7M  934M   1% /opt/renzhiyuan
