Description:
Since Linux V.4.19 the output of `/sys/block/*/stat` might be of 11 (old behaviour) or optionally of 4 additional (15 in total) columns. The current implementation in Archlinux does not accept the 15 column version and makes the plugin crash. The problem was already solved upstream: https://github.com/munin-monitoring/munin/commit/a913c523976bb13b2a34968ee5fe3b55d2b0918f According to github the commit is already present in the upstream stable release. As a result it should sufficient to upgrade to the most recent stable release. Additional info: * munin and munin-node version: 0.26-5 Steps to reproduce: Simply running `munin-run diskstats` results in an error message instead of the actual values reported from the kernel. |
This task depends upon
I file this as a bug report as the package was flagged out-of-date almost 2 years ago and now it bites the user as a functionality no longer works with recent linux kernels.
