The other day I was cleaning off files from my ReadyNAS file system as it was approaching 95% full.
On Linux, I was using the Nautilus file browser which puts them in a Trash Bin rather than erasing them. When I went to empty the Trash Bin, it errored. After that, I could no longer chmod, rm, mv, or touch any files on the ReadyNAS.
If I try to do an
rm filename
I get the error message
rm: remove write-protected regular file `designreview.html'? y rm: cannot remove `designreview.html': Read-only file system
I've tried rebooting the ReadyNAS and my computer. Nothing seems to correct this.
Sounds as if it is a problem with Nautilus that had set a flag on all the files. I know from back in the days of using CDs and DVDs to do backups in Windows, when I would restore a file from the disk this would happen, but I was able to reset the flags, but this was back in the day of XP.
Have you tried Firefox? I know it has releases for Linux. I use it primarily on my Windows 7 machine and it does not do that.
Do you have the trash bin set up for you NAS volume, I do not.
