Update inotify Watchers
This is basically copied from the Crashplan website:
CrashPlan on Linux depends on the inotify kernel module to know when files are
added or edited in real-time. Is the inotify kernel module installed? If not,
you'll need to install it. If inotify is installed, you may need to increase the
number of watches that can be created.
The inotify module is govered by a property called max_user_watches. If you
attempt to exceed the max number you'll get the following error in the
engine_error.log (but the process lives on).
inotify_add_watch: No space left on device
Any file not covered by a watch does not have real-time backup protection.
Incidentally a “watch” could be a file, directory or any other filesystem
element. A given watch can catch multiple types of events or just 1, so how
efficient the watch creation is depends on the library used. The bad news is
that the max number by default is 8192, which is pretty darned low for our
customers running clients with a 100k backup file selection.
Updating the Watch Value
You can temporarily update the value with:
echo 1048576 > /proc/sys/fs/inotify/max_user_watches
You can update the value permanently by putting the following value in
/etc/sysctl.conf and restarting:
fs.inotify.max_user_watches=1048576
Fix Crashing At Start-up
If the ui_output.log file (default location: /usr/local/crashplan/log) displays
an error similar to the following:
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00007f1d89bd7009, pid=14960, tid=139766130898688
#
# JRE version: 6.0_25-b06
# Java VM: Java HotSpot(TM) 64-Bit Server VM (20.0-b11 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# C [libsoup-2.4.so.1+0x6e009] short+0x19
#
# An error report file with more information is saved as:
# /tmp/hs_err_pid14960.log
#
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp
# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.
#
then edit run.conf (default location: /usr/local/crashplan/bin/) in your
Crashplan app directory. Navigate to the end of the GUI_JAVA_OPTS section and
add this line, inside the quotes:
-Dorg.eclipse.swt.browser.DefaultType=mozilla
If it still crashes, run:
sudo apt-get update && sudo apt-get install libwebkitgtk-3.0-0
