Windows OS server discovery missing Disk Partitions reference relationships to File SystemsDescriptionThe Windows OS Server pattern is not creating reference relationships to file systems due to incorrect volume_key formed in step 26.53 of the Windows Storage library. The condition fails in step 26.54, causing the merge tables to not merge correctly. This issue results in the "Provided by" field being empty on the File Systems tab of Windows Server CIs (2012 and above). Affected library: sa_pattern_87e5921edbc12200c06776231f96190a.xml.Steps to Reproduce 1. Hop into instance mtbdev.2. Execute Quick Discovery against the target 10.98.60.59 using MID server PCL_MID_PROD_SNDEV.3. Open the CI after Discovery is completed.4. Navigate to the CI discovered and navigate to related list > File Systems > Provided by is empty.WorkaroundThe regex on step 26.53. "Assign volume key to PartitionToVolume table" is conceptually wrong, the regex there should be changed from:var rgx = /Volume\{\w+-(.*)\}/;to:var rgx = /ObjectId\=\\\"\{(\w+-.*)\}\:/;The regex should not use the Volume number but the Volume.ObjectId number Refer the attached screenshot: Related Problem: PRB1739517
