Regular ZED messages in syslog?

[n1nj4888]

Hi There,

I'm running latest pve and using ZFS replication between local-zfs on 2 nodes. Every time the replication runs it seems to output the following type of messages in syslog without any clear meaning what they are referring to or whether they are just unnecessary noise?

Hi,

this messages is useless, you can disable this message in script: /etc/zfs/zed.d/all-syslog.sh
Also you can see same issue in github [1]

I had the same issue, here is a one liner in case anyone else needs it.

sed -i "s/zed_log_msg/if [ \"\${ZEVENT_SUBCLASS}\" = \"history_event\" ]; then exit 0; fi\nzed_log_msg/g" /etc/zfs/zed.d/all-syslog.sh

You can also uncomment this line:
#ZED_SYSLOG_SUBCLASS_EXCLUDE="statechange|config_*|history_event"
in /etc/zfs/zed.d/zed.rc to prevent those types of events from being logged
