Memory full

Hello,

I wanted to install via opkg an ftp server (opkg install openssh-sftp-server) but failed due to memory full.
See picture. How can I expand the rootfs ?

Thank you
Leo

@Leo,
Memory and disk storage are not the same. You are out of disk space.

How to expand the Yún disk space

Maximum SD Size: 32GB
Hint: You can use more that 700MB for hte Data partition. This is partition you can share with Windows and similar file systems.

Hey Jesse,

Thx for the help.

I ran into problems because I first did a Yun diskspace expand and afterwards a did an upgrade of OpenWrt.
The OpenWrt upgrade succeeded but somehow (maybe thats normal) the initial file system partitioning was installed. (see the png)

I somehow overlooked this until I ran into trouble -:frowning:

A new diskspace expand solved the issue.

Thanks again.

@Leo,
Something not well documented with Arudino Yun, is that part of the file system is READ ONLY. This part (partition) is a fall back in case of system error. Any remaining part on your SD is split between the “shared” filesystem (which windows can read) and the other (third) partition

FWIW, here is my system. To be clear, overlayfs: is part of the READ ONLY filesystem.

Lastly, if you need more room, reformat your SD or get a bigger SD.
