阿里云ecs 硬盘在线扩容详细教程
<p>一、首先在阿里云后台通过在线扩容扩容硬盘</p>
<p>
二、登录ecs下载阿里云gdisk工具</p>
<div class="cnblogs_code">
<pre>

Complete</span>!</pre>
<p>
三、下载阿里云growpart工具</p>
<div class="cnblogs_code">
<pre>
# <span>yum</span> <span>install</span> cloud-utils-growpart -<span>y
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Resolving Dependencies
</span>--><span> Running transaction check
</span>---> Package cloud-utils-growpart.noarch <span>0</span>:<span>0.29</span>-<span>5</span><span>.el7 will be installed
</span>--><span> Finished Dependency Resolution

cloud</span>-utils-growpart.noarch <span>0</span>:<span>0.29</span>-<span>5</span><span>.el7
Complete</span>!</pre>
<p>
四、运行growpart进行扩容分区</p>
<p>
首先通过df -h查看当前硬盘挂载信息</p>
<div class="cnblogs_code">
<pre>
# <span>df</span> -<span>h
Filesystem SizeUsed Avail Use</span>%<span> Mounted on
</span>/dev/vda1 197G<span>4</span>.9G182G <span>3</span>% /<span>
devtmpfs </span><span>7</span>.8G <span>0</span><span>7</span>.8G <span>0</span>% /<span>dev
tmpfs </span><span>7</span>.8G <span>0</span><span>7</span>.8G <span>0</span>% /dev/<span>shm
tmpfs </span><span>7</span>.8G504K<span>7</span>.8G <span>1</span>% /<span>run
tmpfs </span><span>7</span>.8G <span>0</span><span>7</span>.8G <span>0</span>% /sys/fs/<span>cgroup
</span>/dev/vdb1 985G846G 89G<span>91</span>% /<span>home
tmpfs </span><span>1</span>.6G <span>0</span><span>1</span>.6G <span>0</span>% /run/user/<span>0</span></pre>
<p>
发现/dev/vdb1对应的挂载点/home，空间使用91%，需要对/dev/vdb1 的分区进行扩容</p>
<div class="cnblogs_code">
<pre>
# growpart /dev/vdb <span>1</span><span>
CHANGED: partition</span>=<span>1</span> start=<span>2048</span> old: size=<span>2097149952</span> end=<span>2097152000</span> new: size=<span>4194301919</span> end=<span>4194303967</span><span>
# </span></pre>
</div>
<p>
五、运行resize2fs命令扩容目标分区文件系统</p>
<p>
首先查看文件系统类型</p>
<div class="cnblogs_code">
<pre>
# <span>cat</span> /etc/<span>fstab
#
# </span>/etc/<span>fstab
# Created by anaconda on Thu Nov </span><span>29</span> <span>03</span>:<span>34</span>:<span>10</span> <span>2018</span><span>
#
# Accessible filesystems, by reference, are maintained under </span><span>'</span><span>/dev/disk</span><span>'</span><span>
# See </span><span>man</span> pages fstab(<span>5</span>), findfs(<span>8</span>), <span>mount</span>(<span>8</span>) and/or blkid(<span>8</span>) <span>for</span> <span>more</span> <span>info</span><span>
#
UUID</span>=b98386f1-e6a8-44e3-9ce1-a50e59d9a170 / ext4 defaults <span>1</span> <span>1</span>
/dev/vdb1 /home ext4 defaults <span>0</span> <span>0</span><span>
# </span></pre>
<p>
/dev/vdb1文件系统类型为ext4,运行如下命令</p>
<div class="cnblogs_code">
<pre>
# resize2fs /dev/<span>vdb1
resize2fs </span><span>1.42</span>.<span>9</span> (<span>28</span>-Dec-<span>2013</span><span>)
Filesystem at </span>/dev/vdb1 is mounted on /home; on-<span>line resizing required
old_desc_blocks </span>= <span>125</span>, new_desc_blocks = <span>250</span><span>
The filesystem on </span>/dev/vdb1 is now <span>524287739</span> blocks <span>long</span><span>.
# </span></pre>
<p>
再次查看硬盘</p>
<div class="cnblogs_code">
<pre>
# <span>df</span> -<span>h
Filesystem SizeUsed Avail Use</span>%<span> Mounted on
</span>/dev/vda1 197G<span>4</span>.9G182G <span>3</span>% /<span>
devtmpfs </span><span>7</span>.8G <span>0</span><span>7</span>.8G <span>0</span>% /<span>dev
tmpfs </span><span>7</span>.8G <span>0</span><span>7</span>.8G <span>0</span>% /dev/<span>shm
tmpfs </span><span>7</span>.8G504K<span>7</span>.8G <span>1</span>% /<span>run
tmpfs </span><span>7</span>.8G <span>0</span><span>7</span>.8G <span>0</span>% /sys/fs/<span>cgroup
</span>/dev/vdb1 <span>2</span>.0T846G<span>1</span>.1T<span>46</span>% /<span>home
tmpfs </span><span>1</span>.6G <span>0</span><span>1</span>.6G <span>0</span>% /run/user/<span>0</span><span>
# </span></pre>
<p>
/dev/vdb1的容量已经扩围2.0T，至此在线扩容成功。</p>
