Ubuntu无法识别系统可用空间
我最初创建了一个带有10 GB存储空间的虚拟磁盘（带有虚拟盒）。 我已经安装了ubuntu。 它开始显示存储低的警告，所以我将虚拟磁盘容量更改为25 GB。 但是当我运行ubuntu它会一直显示相同的警告时，似乎ubuntu无法识别新的可用空间。
怎么解决这个问题？
运行此命令后：
lsblk -o name,size,type,fstype,mountpoint 我懂了：
NAME SIZE TYPE FSTYPE MOUNTPOINT loop0 4.9M loop squashfs /snap/canonical-livepatch/41 loop1 29.5M loop squashfs /snap/sublime-text/18 loop2 86.6M loop squashfs /snap/core/4486 loop3 139.4M loop squashfs /snap/chromium/343 loop4 86.6M loop squashfs /snap/core/4650 loop5 139.8M loop squashfs /snap/chromium/353 sda 25G disk ├─sda1 1M part └─sda2 10G part ext4 / sr0 55.3M rom iso9660 /media/dk/VBox_GAs_5.2.12

（它没用）
结果3：
sudo parted /dev/sda -- resizepart 2 -1s Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all of the space (an extra 31457280 blocks) or continue with the current setting? parted: invalid token: 2 Fix/Ignore? y parted: invalid token: y Fix/Ignore? f Partition number?
我应该放哪个分区号码？
我应该放什么价值？ 25 gb（或以兆字节为单位？）或者我应该给予更少（与其他系统/分区空间一起计算）？

您需要扩展分区/dev/sda2以覆盖新添加的空间，然后您需要调整文件系统的大小以填充分区。
-
将
/dev/sda2扩展到磁盘的末尾。如果磁盘使用MBR分区方案，那么很容易：
sudo parted /dev/sda -- resizepart 2 -1s如果磁盘使用GPT分区方案，则运行
sudo parted /dev/sda并手动扩展分区号
2。 -
调整文件系统大小以填充分区：
sudo resize2fs /dev/sda2
