Excel 2007 hidden lock

m_doscher — Thu, 05 Jun 2025 07:19:04 GMT

stumbled on a hidden file lock today. oplocks are set to On on the FAS2050, Ontap version 7.3.1.1

In windows server management console, file doesn't list as open for reading or writing. In filer console, locks status at the filer or folder level don't show a lock on the file, as in:

Prolific> lock status -f /vol/projects/00001ma-pm
No locks

but if i check at the file level,

Prolific> lock status -f /vol/projects/00001ma-pm/file.xlsx
========013e0239:01038182
CIFS path=\00001ma-pm\Morphpm-global.xlsx(/vol/projects/00001ma-pm/file.xlsx) host=x.x.x.x() owner=user state=GRANTED mode=RdWr-denyW oplock=None
CIFS path=\00001ma-pm\Morphpm-global.xlsx(/vol/projects/00001ma-pm/file.xlsx) host=x.x.x.x() owner=user pid=65279 offset=2147483539 len=1 excl=yes state=GRANTED
CIFS path=\00001ma-pm\Morphpm-global.xlsx(/vol/projects/00001ma-pm/file.xlsx) host=x.x.x.x() owner=user pid=65279 offset=2147483539 len=1 excl=yes state=GWAITING
CIFS path=\00001ma-pm\Morphpm-global.xlsx(/vol/projects/00001ma-pm/file.xlsx) host=x.x.x.x() owner=user pid=65279 offset=2147483559 len=1 excl=yes state=GRANTED

to break the lock, i used

Prolific> lock break -f /vol/projects/00001ma-pm/file.xlsx

just wanted to share this because i couldn't find any pointers to this on the supprot or community site, and support couldn't find any documentation on it, and from a little googling, sounds like this might happen often with office2007.

Hi,

we are having a similar issues with Ontap 7.2.6.1 and Windows7/Office 2007, 5 cases in the last days.

file is locked (also seeabale in MMC - open files section)
Lock is not deletable with MMC ( you can close the open file, but lock still exists)
no more CIFS-Sessions open for user or host (checked with cifs sessions)

Only way is to remove the lock with the "lock break -f file -p cifs" command

filer*> lock status -f "/vol/vol0/file.xls"

Does anybody has similar experience and maybe a solution for this issues?

Hi,

as i have seen a fix to this issue should be out now in 7.3.2P6 (BUG: 374232)

http://now.netapp.com/NOW/download/software/ontap/7.3.2P6/

still untested from my side because we need to wait for the next scheduled downtime,

but if you get positive results with this release please give feedback

Best Regards,

Klaus

Thank for your answer.

I open a case with NetApp support. They directed me to the same bug (374232).

We will install release 7.3.2P6 on our filer in the days to come.

Sorry for my poor english (thank to Google).

Hi,

I am seeing the same issue. Did the bug fix resolve it? Is there anyway of reporducing the issue from say excel 2007 on the fly? I'd imagine a shared workbook on excel 2007 uses byte range locks?

We have recently upgraded Ontap from 7.3.2 P2 to & 7.3.5.1 P5 which fixed the excel file locking issues.
