Better warnings would be good but I think the actual issue should really be fixed.

Bug#614602: long filenames and loop devices are a problem?
Package: collectd Version: 4.10.1-1+squeeze2 sub...@bugs.debian.org Linux debiani 2.6.32-5-vserver-686 #1 SMP Wed Jan 12 06:32:10 UTC 2011 i686 GNU/Linux Hello collectd worked great, but recently i gott error message my email was growing too fast 3M an hour... I have logcheck running and found: The log fills is filling up with this missleading error messages below. That seems to be caused by too small buffer sizes for "DF" filename generation and the usage of df on a loop mount. 1. Maybe a message complaining "File is ready in use" would ease error finding a lot if this for 99,9% true 2. The buffer length for filename should be made longer or 3. if the filename is to be truncated a warning message should be issued 4. The df_plugin should ignore "loop" mounts as the df command is not delivering any data! debiani:/home2/home/samba/public/MIRROR# tail -f /var/log/syslog Feb 22 15:43:15 debiani collectd[7893]: uc_update: Value too old: name = debiani/df/df-home2-home-samba-public-MIRROR-WINDOWS-WSUSOffline-wsusoffline-; value time = 1298385795; last cache update = 1298385795; Feb 22 15:43:15 debiani collectd[7893]: Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -1.
