ubuntuone client should warn if max_user_watches is reached

[Roberto Suárez Soto]

Hi,

I'm running Ubuntu One and Dropbox (and previously, yet another file synchronization service) in the same box, and I've hit the limit of max_user_watches (/proc/sys/fs/inotify/max_user_watches) a few times, because I have a bazillion small files in the directories that I'm sincying.

Dropbox client warns you when you hit the limit, and tells you how to solve it ("echo 10000 > /prox/sys/fs/inotify/max_user_watches"). It would be good that U1 client did it too, because I had a problem of some folders not syncing and had to scratch my head for a while until I realized it was caused by this.

Thanks in advance.

That would be better suggested as “sudo sysctl -w fs.inotify.max_user_watches=10000” (although 10k might or might not be the right number, there).

Or just read it, double it, and show the user a dialog saying "You have run into a limit for file system watches. To make Ubuntu One work properly, this has to be increased to NNNN" and using gksudo or whatever to get it done.
