I getting -1 as value back from some servers for the offline bricks and the self heal status.

Looking to the collection script:

if item=$(timeout -s 9 1 sudo gluster volume status 2>/dev/null | grep rick1 | awk '{print $4}'); then echo "$item" | grep -c N; else echo '-1'; fi

-1 will be displayed after a timeout - right?

Have running the command line above parallel in a loop on the same machine. The output of the loop was within one hour everytime 0, but the agent sends over 6 times within this hour a -1

Any ideas?

Have now set the timeout from 1 to 2 seconds: ... timeout -s 9 2 sudo ...

1st Issue
[root@cluster-stor1 gluster]# sh heal.sh ' ' 0
=> no value returned, so Trigger detects a pending healing but there isn't:
