Bug 453266 – app-backup/spideroak-bin-4.8.3 backup frequency on automatic fails to find newer files: fs_notify: Error starting notifier: /opt/SpiderOak/lib/inotify_dir_watcher: Permission denied

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Krzys Baranski 2013-01-21 02:39:34 UTC]

backup not working for new files when backup frequency is set to automatic.
But works after restart or using manual rescan button.

at least file /opt/SpiderOak/lib/inotify_dir_watcher should be set as executable
but it not realy helps.

Error log ~/.SpiderOak/spider_20130120020022.log:
2013-01-20 02:00:52,564 ERROR    fs_notify            Error starting notifier: /opt/SpiderOak/lib/inotify_dir_watcher: Permission denied


Reproducible: Always

Steps to Reproduce:
1. run SpiderOak
2. set backup frequency to automatic
2. update or add new file to backup folder
Actual Results:  
nothing happens, file is not uploaded.

Expected Results:  
new files should be immediately backed up.

After:
# chmod +x /opt/SpiderOak/lib/inotify_dir_watcher

it works, but I had to increase value max_user_watches
# echo 262144 > /proc/sys/fs/inotify/max_user_watches
can be set it permanently in file: /etc/sysctl.d/30-spideroak.conf

before changing max_user_watches I get following error:
~/.Spideroak/fs_notify__dir_watcher_ignore/error.txt
inotify_add_watch /home/user/dir 28 No space left on device

Thanks for spotting this for us. Both look reasonable.  However, I will not run sysctl from an ebuild after dropping in 30-spideroak.conf.  I will put in an ewarn that the user should do it.

Comments before I make the magic happen?

I'm not sure about the change in max_user_watches,
I think that it's only needed when there
are large number of folders in backup.

Maybe default (65536) would be OK for most people.

Okay this is fixed with spideroak-bin-4.8.3-r1.  I'm going to skip the issue with sysctl on max_user_watches since this is documented in their forums.

Please test and reopen if its still a problem.  Thanks for the report!
