I'm wondering if this is bug or a known fact on NAND. I build a NAND image from snapshot with the imagebuilder:
and installed it on an GL.inet AR750s. The system boots and is ready. I have a setup where I move /etc/config and symlink it for atomic config updates. But the jobs that actually moves /etc/config gets:
root@NW-C1000M:~# mv /etc/config/ /etc/config-orig mv: can't remove '/etc/config/': I/O error
If I do the exact same mv on NOR image
root@NW-C1000M:~# mv /etc/config/ /etc/config-orig root@NW-C1000M:~# mv /etc/config-orig/ /etc/config
i found the following message in the boot log. Not sure if it is at all related but it doesn't appear on NOR image:
[ 19.819306] overlayfs: upper fs does not support xattr, falling back to index=off and metacopy=off.
any hints very much appreciated.
