Description of problem:

While performing inservice upgrade of ganesha cluster from RHEL7.5/RHGS 3.4 to RHEL7.6/RHGS 3.4.1, error messages related to ganesha_use_fusefs boolean and ganesha log file are seen while packages upgrade is in process.

Whereas ganesha process comes up successfully without any failures while performing in-service upgrade.

Following AVC's was observed while starting ganesha service post upgrade-

# cat /var/log/audit/audit.log | grep AVC | grep ganesha
type=AVC msg=audit(1538532359.058:179): avc:  denied  { search } for  pid=18074 comm="ganesha.nfsd" name="net" dev="proc" ino=2429 scontext=system_u:system_r:nfsd_t:s0 tcontext=system_u:object_r:sysctl_net_t:s0 tclass=dir permissive=0


Setting of boolean "ganesha_use_fusefs" is failing post upgrade-

# setsebool -P ganesha_use_fusefs on
Failed to change boolean ganesha_use_fusefs: No such file or directory

How reproducible:
2/2

Steps to Reproduce:
1.Create 5 node ganesha cluster on  RHEL7.5/RHGS 3.4
2.Create a volume
3.Export the volume via ganesha and mount it on client
4.Perform inservice upgrade

Actual results:

Error/warnings wrt boolean and log file is seen when package upgrade is in process

Expected results:

No failures ahould be seen
