A customer intranet died the other morning. The is what happend.
First user notifies of error while trying to access.
I start to look into it.
- First issue. Low/none diskspace. Frees up so its workable. This does nothing for the site. Tries restart to no avail.
- Checks all IIS-sites and Application Pools. A lot of pools are stopped. Starts these up, but not difference.
- Notices that patches been applied the previous night. Server starts warning for diskspace soon after. Ok so maybe a patch requires psconfig. Runs this but are greeted with error: Failed to initiate the upgrade sequence…. Method not found ‘void Microsoft.Sharepoint.WorkflowServices.Iworkflowservice.upgrade….
searching for this error doesn’t give much. Tries to uninstall the workflow manager services for this seems to related. the workflow 2013 mananger has given some ache in the past and isn’t used anyways. This gives nothing.
Tries to access Central Administration and curiously this works to certain degree. Until tries to access Service Application then it throws iWorkflowServices errors again.
Looks deeper into the logs and finds issues with the patches being applied.
Ok, so maybe a patch was trying to be applied but got stuck on the diskissue and landed in some unfinished state?
Tries to download the latest updates to see if this is an issue. There is some, but it takes alot of time.
Checks the size of the culprits Kb2863829. Turns out this mother is 827MB, no wonder it takes time. AND the patch requires and psconfig run after completion!
Let the update run through and then runs psconfig again. Though this failes on the Task 8 in the first run (Failed to create sample data) another run let it finishes.
Now everything works again!
What to take with us from this experience?
Always have 10-20GB free space on the sharepointserver!
