read-only access on rootfs
« on: 28 July 2010, 11:06:27 pm »

Hi,

after my USB-ports and my microSD-Slot have been killed I think I have found a new feature:
I cannot write data on any part of the internal memory of the plug, even if logged in as root.
The command "touch A" yields:
touch: cannot touch `A': Read-only file system

Rebooting, remounting etc. did not bring any relief, the fstab file is unchanged and looks fine.
Writing data on hard drives attached via eSATA works fine.
Any ideas?

If a log were written during boot (which it's not, because the file systems was mounted read-only), there should be a hint in the log. If you have a JTAG you can view the messages and / or rewrite the rootfs, which I expect is the only possible solution.

Hm, the problem seems to have solved itself.
After keeping the plug idle for some time I rebooted it again, and suddenly it worked again ...

So I guess it's some heat-related protection mechanism, still it's really annoying as most programs
which require write-access crash if all of a sudden the partition is read-only :/
