Description Karel Srot 2011-05-26 10:19:18 UTC

Description of problem:

The same problem with XFS detection is on RHEL6
net-snmp-5.5-31.el6.x86_64


--- Copied from 654384 ----------

I have tested this bug with net-snmp-5.3.2.2-12.el5 (see reproducer
https://tcms.engineering.redhat.com/case/92807/)
but snmpd does not see the XFS filesystem while the old version does.

How reproducible:
always

Steps to Reproduce:
1. create and mount xfs filesystem
2. snmpwalk -v2c -c public -v 1 127.0.0.1 hrFSTable 
and check it is not listed
  
Actual results:
xfs filesystem is not listed as mounted

Expected results:
xfs fs is listed as mounted

Additional info:
Also not working with net-snmp-5.5-27.el6.x86_64 from RHEL6.0
