Hello everyone,
a customer has been facing an issue with file-locks (mainly Excel) since migrating a 7-mode sytem into a cDOT SVM.
The cDOT system is a 2-node AFF-A250 HA-Pair and the SVM is used for user and group shares.
A recent update from 9.9.1P5 to 9.11.1P3 did not help with the issue.
Fairly frequently, users trying to open files are denied access with the reply, that the file is already opened by another user.
That is the point where the issue takes a couple of different shapes:
-opening user is reported as the user locking the file
-another user is reported to have the file open
-one user is reported to have the file open but a third user actually has the file open
-a user, whose AD account is deactivated, is reported to have the file open
Unfortunately so far, it was not possible to provoke or reproduce the issue, so currently we don't have any real clue as to what is causing it.
Has anyone encountered this strange behaviour as well or has an idea how to fix it?
Any advice is welcome!
