owlFileUse with NFS or CI

Due to customer complaint/observation we were asked to test and document how well the owlFileuse utility works on CentOS6 & CentOS7.

CIFS (Samba) share

Test devices: 

Windows 2017R2 PI HA primary VM with a shared folder called, "NFS"

CentOS6 VM mounting the SAMBA share in /mnt/samba

CentOS7 VM mounting the SAMBA share in /mnt/samba

Fedora desktop writing /dev/random to the Samba share (NFS directory on Windows server)

 

Results:

CentOS6 - owlFileuse utility detects that the SAMBA share is being written to.  Tested with "-stat 2"  & "-stat 5" options.  PASS

CentOS7 - owlFileuse utility detects that the SAMBA share is being written to.  Tested with "-stat 2"  & "-stat 5" options.  PASS

 

NFS share

Test Devices:

Fedora desktop writing /dev/random to the NFS shared file.  /export/nfstestfile

CentOS6 VM mounting the NFS share in /mnt/nfs/

 

CentOS7 VM mounting the NFS share in /mnt/nfs/

 

Results:

CentOS6 - owlFileuse utility  fails to detect with "-stat 2" option.   FAIL

CentOS7 - owlFileuse utility  fails to detect with "-stat 2" option.   FAIL

 

CentOS6 - owlFileuse utility successfully detects file in use with "-stat 3" (and up to -stat 5) option.   PASS

CentOS7 - owlFileuse utility successfully detects file in use with "-stat 3" (and up to -stat 5) option.   PASS
