If you are packaging this software yourself or you want to compile from source for other reasons, you can follow these instructions.
This software is implemented in Go programming language. Further information about installing the Go environment is available at the following URL:
The version 1.0.3 of the Go programming language on a 64 bit platform is recommended.
The software has been developed on Debian 6.0 (squeeze) and Ubuntu 12.04 (precise) but it should work fine on other Linux distributions and also recent FreeBSD versions.
Optionally edit the Makefile to set the installation directories. Then run:
make
make install
There are some OS/distribution specific startup scripts in "etc" subdirectory. They may be useful.
See the installed zfswatcher(8) manual page for information on invoking the zfswatcher process.
The normal "gc" Go toolchain is not available on this plaform.
You need to compile a recent version of
gccgo from the Subversion
repository at svn://gcc.gnu.org/svn/gcc/branches/gccgo. After that
you can utilize the etc/gccgo-build.sh shell script.
Good luck!
Edit the configuration file:
editor /etc/zfs/zfswatcher.conf
Verify the configuration syntax:
zfswatcher -t
Restart the process:
service zfswatcher restart
Some notes:
-
See the configuration file comments for information about the configuration settings.
-
Enclosure LED management is disabled by default. Currently an external utility
ledctl(part of ledmon package) is required for this functionality. -
Logging to file
/var/log/zfswatcher.logand local syslog daemon is enabled by default. -
E-mail notifications are disabled by default.
-
The embedded web server is disabled by default.
-
If you change the default web interface templates, it is best to copy them from
/usr/share/zfswatcher/wwwto another location and change thetemplatedirandresourcedirsettings in the configuration accordingly. This way your local changes will not be overwritten if you upgrade the package at a later time.
