Hi there,
Thanks for the awesome work on OpenWrt.
I finally succeeded in creating an extroot pivot overlay configuration with a usbstick following the instructions (http://wiki.openwrt.org/doc/howto/extroot, section Chaos Calmer). Read all the docs and posts I could find on extroot.
Then I ran into the problem of a Read-only file system in the extroot configuration. This while it was explicitly set to 'rw,sync' for the overlay 'mount' in the fstab configuration.
No files can be created on /root or any other folder (except the /tmp folder). As a result no packages can be installed, no applications can be upload, can not connect to the internet since no configuration files can be written. Extroot cannot be used like this.
I found one post on stack-overflow about someone meeting this issue (https://stackoverflow.com/questions/310 … s-readonly).
Here you find a gist containing (https://gist.github.com/arneboon/0f1230180d23dcad0b78):
a) the exact steps i took for creating the pivot overlay
b) logs with verious commands while inside the pivor overlay through ssh
One thing that pops out from the dmesg log:
[ 0.520000] 0x0000000ff358-0x0000003f0000 : "rootfs"
[ 0.530000] mtd: partition "rootfs" must either start or end on erase block boundary or be smaller than an erase block -- forcing read-only
[ 0.540000] mtd: device 2 (rootfs) set to be root filesystem
Very much hoping anyone has a solution or suggestion about how to move forward. Thanks in advance!
Best regards from the Netherlands,
Arne.
