[Linux] Resize rootfs in boot time or in runtime

[Chayma]

Hi everyone,

I would like to know if there is a possibility to resize the RootFS  :
- During the boot time
- During the runtime

Note: I am working on iMX8M mini

Thank you in advance.

Best regards,

[Yuri]

Hello,

  It would be better to use special utilities for the resizing, such as parted.
Look at the following document.

Hello,

Thank you for your response.

So, the rootfs resizing during the system runtime and during the system boot are not possible ?

Note : I am using the eMMC

Hello,

   I do not think, that this is good idea to resize rootfs during boot.
At least, I do not know about robust implementations here.
