VMware vSphere vCenter Server installs an Active Directory Application Mode (ADAM) [aka Active Directory Lightweight Directory Service (ADLDS)] instance called VMwareVCMSDS. I have had several problems with this service — one issue with the contents of the directory (see vCenter Migration<\/a>) and a couple with the actual ADAM\/ADLDS instance. In a recent upgrade I moved a lab environment from vSphere 4.0 to 4.1 and started getting the following event log message: <\/p>\n

VMwareVCMSDS (2428) ADAMDSA: Database 'D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\adamntds.dit': The secondary index 'INDEX_00000003' of table 'datatable' may be corrupt. If there is no later event showing the index being rebuilt, then please defragment the database to rebuild the index.<\/pre>\n
The solution to this problem was rather simple — but required working directly with the ADAM instance.  This took a little trial and error but here is a description of the solution in case you run into the same error:<\/p>\n
Stop the VMwareVCMSDS service:<\/p>\n
net stop ADAM_VMwareVCMSDS<\/pre>\n
Enter the directory service database utility application:<\/p>\n
dsdbutil<\/pre>\n
The following commands get you to the file configuration settings:<\/p>\n
\r\nActivate Instance VMwareVCMSDS\r\nFiles\r\ninfo\r\n<\/pre>\n
Here is my test systems file configuration:<\/p>\n
\r\nDrive Information:\r\n\r\nC:\\ NTFS (Fixed Drive  ) free(5.4 Gb) total(23.9 Gb)\r\nD:\\ NTFS (Fixed Drive  ) free(2.6 Gb) total(3.9 Gb)\r\n\r\nDS Path Information:\r\n\r\nDatabase   : D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\adamntds.dit - 4.1 Mb\r\nBackup dir : D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\dsadata.bak\r\nWorking dir: D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\r\nLog dir    : D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS - 30.0 Mb total\r\nedbres00002.jrs - 10.0 Mb\r\nedbres00001.jrs - 10.0 Mb\r\nedb.log - 10.0 Mb\r\n<\/pre>\n
To compact\/defrag the database type the following command in the dsdbutil screen:<\/p>\n
compact to d:\\temp\\defragged<\/pre>\n
Here are the results of the compact operation:<\/p>\n
\r\nInitiating DEFRAGMENTATION mode...\r\nSource Database: D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\adamntds.dit\r\nTarget Database: d:\\temp\\defragged\\adamntds.dit\r\n\r\nDefragmentation  Status (% complete)\r\n\r\n0    10   20   30   40   50   60   70   80   90  100\r\n|----|----|----|----|----|----|----|----|----|----|\r\n...................................................\r\n\r\nIt is recommended that you immediately perform a full backup\r\nof this database. If you restore a backup made before the\r\ndefragmentation, the database will be rolled back to the state\r\nit was in at the time of that backup.\r\n\r\nCompaction is successful. You need to:\r\ncopy \"d:\\temp\\defragged\\adamntds.dit\" \"D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\adamntds.dit\"\r\nand delete the old log files:\r\ndel D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\*.log\r\n<\/pre>\n
I created a zip file contianing all the files in: “D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS” before proceeding with the given instructions.<\/p>\n
\r\ncopy \"d:\\temp\\defragged\\adamntds.dit\" \"D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\adamntds.dit\"\r\n<\/pre>\n
Answering yes to the overwrite files confirmation.<\/p>\n
\r\ndel \"D:\\Program Files\\VMware\\Infrastructure\\VirtualCenter Server\\VMwareVCMSDS\\*.log\"\r\n<\/pre>\n
After completing the defragmentation I started the VMwareVCMSDS service again but had problems authenticating back to vCenter.  Instead of restarting the vCenter service I went ahead and rebooted the server — which seems to have cleared up all my errors.<\/p>\n","protected":false},"excerpt":{"rendered":"
