Hi Neil, On Wed, Oct 24, 2018 at 04:17:34PM +0100, Neil Wallace wrote: I don't use Dropbox but personally I would first just try editing fstab to replace ext3 with ext4 and then see if Dropbox is happy. This does not convert your filesystem to ext4, it only allows you to continue using an ext3 filesystem but with the ext4 driver. Unless you go further to convert the filesystem it will not support all the features of an ext4 filesystem. If Dropbox checks for those features then it might not work. If it doesn't check then it probably will work. If that doesn't work, what about this? https://metabubble.net/linux/how-to-keep-using-dropbox-even-if-you-dont-use… It involves creating an image file, putting an ext4 filesystem on it and then mounting that. This has the disadvantage that it uses the full size of the image file out of your filesystem. You could perhaps try a sparse image, which will only take up space when it's allocated. If none of that was suitable then I'd boot into the rescue VM and convert the filesystem to ext4 (after taking a backup). Of course, if reinstalling is a matter of minutes for you then it might make sense to take the plunge and reinstall on ext4 using amd64 architecture. This initially doesn't actually convert to ext4; all it does is make the ext3 filesystem work through the ext4 driver. If you wanted to try the later things it mentions about migrating to ext4 then you will probably find it easier to do that from the rescue VM as you can boot into it and do the fsck and tune2fs commands against /dev/xvda1 (after taking backups).
