Expand the Storage at Yun

Details

Revert boot to internal flash:

wget -O reset.sh https://www.dropbox.com/s/4g1yfpnas25cepn/reset.sh?dl=0 --no-check-certificate
/bin/ash reset.sh
nano reset.sh
/bin/mkdir -p /mnt/mtdblock3
/bin/mount -t jffs2 /dev/mtdblock3 /mnt/mtdblock3
/usr/bin/head -n 9  /mnt/mtdblock3/etc/config/fstab > /tmp/fstab
/bin/mv /tmp/fstab /mnt/mtdblock3/etc/config/
/sbin/reboot



Plan B:

Shutdown Yun, take out flash then restart Yun.

nano /etc/config/fstab



Remove this block code:

config mount
        option target '/'
        option device '/dev/sda1'
        option fstype 'ext4'
        option enabled '1'
        option enabled_fsck '0'
        option options 'rw,sync,noatime,nodiratime'

restart Yun.

Plan C:

Shutdown Yun, take out flash then restart Yun.

uci delete fstab.@mount[0]
uci commit



restart Yun.
