so I'm trying to start using lsyncd for a more up to date backup system.

the problem that i have run into is that the directory that i have to backup contains more than 250,000 items and i would like to increase the watch size naturally to something like 300,000 watch items, a number that the architects in the office wont reach for a long time. so when i go to do that i access the watch plain text file via:

    sudo gedit /proc/sys/fs/inotify/max_user_watches

and change to 300,000. I hit save but even as sudo it wont let me save the darn file. I have tried doing the same operation while the daemon is off then starting it, check it, still not changed.

the exact error that I get is:

Could not create a backup file while saving /proc/sys/fs/inotify/max_user_watches

so my question is how to effectively change that file's contents from 8192 to 300,000

this website has the answer in the comments about how to edit the file in question.

http://monodevelop.com/Inotify_watches_limit

so that you do not have to search for the comment on the site this is correct command that worked perfectly for me.

echo yourNumber | sudo tee /proc/sys/fs/inotify/max_user_watches

for those of us who didnt know that much about inotify, pay attention to the number that you enter. the number that you enter must be a multiple of 2.

so because i had such a large amount of items to watch (257,048) i wanted to go to a number that was at least as high as 300,000 items being watched. the closest multiple of 2 was 285184, which was not enough for me. thus i multiplied by two to get 570368. so i will probably never have to touch that file again (yay).

enjoy a cup of ubuntu, cheers
