Read-only file system

[twm]

Since upgrading to 2.5, I am having trouble correctly displaying graphs or uploading data to my website.

When I try to create a new graph, I get:

Code: Select all

Error file open: /data/graphs/__test.mg: Read-only file system

[/color]

It also appears that existing graphs are not being created or uploaded, although when I look in the logs, it appear that the cron jobs are running.

Any help would be appreciated. I'm currently running 2.5c

Thanks.

If you have not pulled the USB stick during operation this is a clear indication that the USB stick or NSLU2 are not working correctly. Try to save your weather data and setup a new USB stick from the USB stick images from scratch.

There is no other cure for a corrupted file system. sorry.

I had a similar problem after updating. I couldn't get the application backup to work on the older level so I saved the weather files with copy and paste with windows to save on windows from meteohub. After restoring the files the graphs failed on the newer level (2.4e). I my case I think I edited the raw weather files with windows using KEDIT which put carriage return and line feeds for the end of line code. Linux expects only a line feed. I was able to get things going again by setting the editor option to encode the end of line with line feed only. Also I found some garbage in the raw file which I deleted and then I sorted the records to make sure they were in order by time recorded. It still would not work until I found some duplicate records in the raw file and deleted the extra records. Of course I had to have meteohub recalculate the weather data in order to make the graphs work OK.

I just now noticed this part of your post:

Code:
Error file open: /data/graphs/__test.mg: Read-only file system

My meteohub system remounted to read-only also. I saw the remount message in the log. It set it a while after a startup. You could change files right after a restart, but after a while it would become read-only. This was after I had updated meteohub, but did not have the compatible firmware installed. After updating firmware to 2.6.21.7 I think from 2.6.16.... that problem went away.
