Fix repository corruptions using CRX console

When you run a consistency check and fix on your PersistenceManager, you get one or more of the following errors in the log. (It's likely that your uuids differ from these errors.)

• ChildNode has invalid parent id: 651da1a9-fdbb-49ca-b908-8939d0fb7976 (instead of d3fb8c83-5453-421b-a862-245a4b243af2)
• NodeState 4ee97820-2137-48e0-b664-f804c34eb24f references inexistent child {}node3_etc_workflow_instances_2009-09-22_delete_asset_497741622317431 with id dd7e1f37-9480-4c40-af45-218db4c48190
• NodeState '80b19738-b62b-4a6a-af9b-70f245d2a7bc' references inexistent parent uuid '9b353130-29f4-4825-8c20-03f3a8786e5a'
  
• javax.jcr.ItemNotFoundException: failed to build path of 46bbf932-3bd1-466d-bf93-7e0c99dc5707: ad09118a-45cb-422d-b201-e0cbc938ade7 has no child entry for 46bbf932-3bd1-466d-bf93-7e0c99dc5707
  
• ConsistencyCheck: Not repairable: Node 918fea28-f6ab-42bc-aff4-008d073632db has unknown parent: 42d4bb3e-2107-4560-ad54-f309b0db02dc (ConsistencyCheck.java, line 116)
  

Or, when you are reindexing the search index, it fails with this error (with the same uuid displayed):

NoSuchItemStateException: deadbeef-cafe-babe-cafe-babecafebabe.

Solution

If your problem matches one those listed above, then the following process will help you fix the corruption.

Until CRX 2.2 , use the old CRX Console :

1. Stop your CRX instance (CRX Console does not work while CRX is running)
2. You may need to correct the startup script for the Console. To do that, edit server/console.sh, and replace the variable REPOSITORY_HOME="$CONTEXT/crx" with REPOSITORY_HOME="$CONTEXT/../repository". (Please note you can't just add the line to the top of the script, because the CONTEXT may not be set before that which would cause the console use a different repository).
3. For CQ 5.3/CRX 2.x : copy server/lib/common/cq-shared-libs-5.3.4.jar to server/lib/container
   
4. To start the CRX Console, in a terminal window, type:
   crx-quickstart/server./console.sh
5. After the console prompt is displayed then type the following command to login as admin:
   login crx.default admin <pwd>
   

Fix "ChildNode has invalid parent id"

From the CRX Console, follow these steps:

• For example, if you had this error:
  ChildNode has invalid parent id: INVALID_PARENT_UUID (instead of EXPECTED_PARENT_UUID)
  
  Run this command to get a low level view of the "correct" parent node:
  stat EXPECTED_PARENT_UUID
  
  Then run a stat for each of the child nodes and verify that the parentId is EXPECTED_PARENT_UUID.
  
• fix the ones that have the wrong id using the patch command like this:
  patch -p EXPECTED_PARENT_UUID CHILD_UUID
  

How to Fix "NodeState references inexistent child"

From the CRX Console, follow these steps:

1. For example, if you had this error:
   NodeState 4ee97820-2137-48e0-b664-f804c34eb24f references inexistent child {}node3_etc_workflow_instances_2009-09-22_delete_asset_497741622317431 with id dd7e1f37-9480-4c40-af45-218db4c48190
   
2. Run this command to get the path of the NodeState item
   stat 4ee97820-2137-48e0-b664-f804c34eb24f
   
3. Use the path that it output by the above command as the [path] argument for this command:
   cd [path]
   
4. Run these commands to remove the missing child node reference, save and exit:
   rm -c dd7e1f37-9480-4c40-af45-218db4c48190
   save
   exit
5. If you can afford the downtime, then run a full search index consistency check and fix to remove the orphan node from your search index. See this article for how this is done. Otherwise continue with the following steps.
6. Make sure CRX is stopped at that point. Create a file named redo_X.log under crx-quickstart/repository/workspaces/<workspace>/index/ where the X in the file name matches what is in the end of the filename for the crx-quickstart/repository/workspaces/<workspace>/index/indexes_X file. In the file enter the following:
   1 DEL dd7e1f37-9480-4c40-af45-218db4c48190
   1 COM
7. Start CRX
8. If everything was done properly then you should see log messages like these in your logs/crx/error.log upon startup of CRX:
   *INFO * Recovery: Found uncommitted redo log. Applying changes now... (Recovery.java, line 82)
   *INFO * Recovery: Redo changes applied. (Recovery.java, line 85)
   

Fix "references inexistent parent uuid" and "ConsistencyCheck: Not repairable: Node ... has unknown parent: ..."

From the CRX Console, follow these steps:

1. For example, if you had this error:
   NodeState '80b19738-b62b-4a6a-af9b-70f245d2a7bc' references inexistent parent uuid '9b353130-29f4-4825-8c20-03f3a8786e5a'
2. Run these commands to remove the orphan child node save and exit:
   rm [80b19738-b62b-4a6a-af9b-70f245d2a7bc]
   save
   exit
3. If you can afford the downtime, then run a full search index consistency check and fix to remove the orphan node from your search index. See&nbsp;this article&nbsp;for how this is done. Otherwise continue with the following steps.
4. Make sure CRX is stopped at that point. Create a file named redo_X.log under crx-quickstart/repository/workspaces/<workspace>/index/ where the X in the file name matches what is in the end of the filename for the crx-quickstart/repository/workspaces/<workspace>/index/indexes_X file. In the file enter the following:
   1 DEL 80b19738-b62b-4a6a-af9b-70f245d2a7bc
   1 COM
5. Start CRX
6. If everything was done properly then you should see log messages like these in your logs/crx/error.log upon startup of CRX:
   *INFO * Recovery: Found uncommitted redo log. Applying changes now... (Recovery.java, line 82)
   *INFO * Recovery: Redo changes applied. (Recovery.java, line 85)

Note: If you have many errors to fix then you can prepare multiple items in these steps:

In step 4, open a text file and prepare multiple rm commands then paste the whole file's contents into the CRX console, for example:
rm [<child uuid 1>]
rm [<child uuid 2>]
save
exit

In step 6, you would have multiple items in the redo_X.log enter as below:
1 DEL <child uuid 1>
1 DEL <child uuid 2>
1 COM

You would replace the <child uuid 1> with the actual uuids of the child node in the error message, like in the example given above this would be 80b19738-b62b-4a6a-af9b-70f245d2a7bc

Fix "javax.jcr.ItemNotFoundException: failed to build path of ... has no child entry for ..."

From the CRX Console, follow these steps:

1. For example, if you had this error:
   javax.jcr.ItemNotFoundException: failed to build path of 46bbf932-3bd1-466d-bf93-7e0c99dc5707: ad09118a-45cb-422d-b201-e0cbc938ade7 has no child entry for 46bbf932-3bd1-466d-bf93-7e0c99dc5707
   
2. Run these commands to delete the orphan child node, save and exit the crx console
   rm [46bbf932-3bd1-466d-bf93-7e0c99dc5707]
   save
   exit
   
3. If you can afford the downtime, then run a full search index consistency check and fix to remove the orphan node from your search index. See this article for how this is done. Otherwise continue with the following steps.
4. Make sure CRX is stopped at that point .Create a file named redo_X.log under crx-quickstart/repository/workspaces/<workspace>/index/ where the X in the file name matches what is in the end of the filename for the crx-quickstart/repository/workspaces/<workspace>/index/indexes_X file. In the file enter the following:
   1 DEL 46bbf932-3bd1-466d-bf93-7e0c99dc5707
   1 COM
5. Start CRX
6. If everything was done properly then you should see log messages like these in your logs/crx/error.log upon startup of CRX:
   *INFO * Recovery: Found uncommitted redo log. Applying changes now... (Recovery.java, line 82)
