Hello,
I created some hosts at time of 4.3.3 or similar and connecting to iSCSI I set this in multipath.conf to specify customization

"
# VDSM REVISION 1.5
# VDSM PRIVATE

# This file is managed by vdsm.
...
"

Then I updated the environment gradually to 4.3.8 but of course the file remained the same because of its configuration and the "PRIVATE" label.
Now I install new hosts in 4.3.8 and I see that by default they have these lines

"
# VDSM REVISION 1.8

# This file is managed by vdsm.
"

So the question is:
suppose I customize the multipath.conf file using the "# VDSM PRIVATE" line, how do I have to manage the REVISION number as time goes on and I execute minor updates to hosts?
What will it change between 1.5 above and 1.8? Any impact if I leave 1.5 for example across all my 4.3.8 hosts?
You are not supposed to edit revision numbers of the conf file as it is managed by vdsm internally for reconfiguration checks on upgrades.
for implications, you can compare files for 1.5 and 1.8 to see the diff.

Thanks in advance for clarification,
Gianluca
