Enable Journal Wrap Automatic Restore

Question, does this retrieve information from another server to replace what is on the server with the issue? The reason I ask is this. I have a 2003 DC which I want to migrate over to a 2012 R2 server. I have noticed that the 2012 server will not allow logins if the 2003 server is down. So I was going to use Burflags to move the info over. However I have noticed that the 2003 server has the journal wrap error. It is the one with all the info so if it is delete all of my data is gone since the other server does not have that info. So I guess my question is this: Can I do this on the main server that has the current information? If not, what is my next step?

Log Name: File Replication ServiceSource: NtFrsDate: 4/11/2010 9:32:13 AMEvent ID: 13568Task Category: NoneLevel: ErrorKeywords: ClassicUser: N/AComputer: ADC.fabrikam.comDescription:The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR. Replica set name is : "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" Replica root path is : "c:\windows\sysvol\domain" Replica root volume is : "\\.\C:" A Replica set hits JRNL_WRAP_ERROR when the record that it is trying to read from the NTFS USN journal is not found. This can occur because of one of the following reasons. [1] Volume "\\.\C:" has been formatted. [2] The NTFS USN journal on volume "\\.\C:" has been deleted. [3] The NTFS USN journal on volume "\\.\C:" has been truncated. Chkdsk can truncate the journal if it finds corrupt entries at the end of the journal. [4] File Replication Service was not running on this computer for a long time. [5] File Replication Service could not keep up with the rate of Disk IO activity on "\\.\C:". Setting the "Enable Journal Wrap Automatic Restore" registry parameter to 1 will cause the following recovery steps to be taken to automatically recover from this error state. [1] At the first poll, which will occur in 5 minutes, this computer will be deleted from the replica set. If you do not want to wait 5 minutes, then run "net stop ntfrs" followed by "net start ntfrs" to restart the File Replication Service. [2] At the poll following the deletion this computer will be re-added to the replica set. The re-addition will trigger a full tree sync for the replica set. WARNING: During the recovery process data in the replica tree may be unavailable. You should reset the registry parameter described above to 0 to prevent automatic recovery from making the data unexpectedly unavailable if this error condition occurs again. To change this registry parameter, run regedit. Click on Start, Run and type regedit. Expand HKEY_LOCAL_MACHINE. Click down the key path: "System\CurrentControlSet\Services\NtFrs\Parameters" Double click on the value name "Enable Journal Wrap Automatic Restore" and update the value. If the value name is not present you may add it with the New->DWORD Value function under the Edit Menu item. Type the value name exactly as shown above.

Journal wrap errors occur if a sufficient number of changes that occur while FRS is turned off in such a way that the last USN change that FRS recorded during shutdown no longer exists in the USN journal during startup. The risk is that changes to files and folders for FRS replicated trees may have occurred while the service was turned off, and no record of the change exists in the USN journal. To guard against data inconsistency, FRS asserts into a journal wrap state.

To perform maintenance on FRS replica set members, administrators may stop the FRS service for long periods of time. In this case, administrators may not realize the potential impact. Also, error conditions may cause the FRS service to shut down, and this causes a journal wrap error. In large replica sets, replica members may encounter the following error during an authoritative restore (BURFLAGS=D4):

For Windows 2000 computers that use versions of the Ntfrs.exe file from Windows 2000 Service Pack 2 (SP2) or from Windows 2000 SP2 hotfix (WINSE 11773), the service performs a programmatic nonauthoritative restore when the journal_wrap_error is detected.

By default, versions of the Ntfrs.exe file from Windows 2000 Service Pack 3 (SP3) and from Windows 2000 SP3 hotfix don't perform an automatic nonauthoritative restore (for example, SP3 leaves content in place as 2195 and SP1 left the context in place) when journal wrap errors are detected. SP3 versions of NTFRS may be configured to function like SP2 when the "Enable journal wrap automatic restore" registry entry is set to 1 in the following registry subkey: HKLM\System\Ccs\Services\Ntfrs\Parameters

If you increase the USN journal size, and therefore you increase the number of changes that the journal can hold before the journal "wraps," this reduces the possibility that the USN journal wrap will occur. The USN journal size can be changed by setting the following registry key: HKLM\System\CCS\Services\NTFRS\Parameters\"Ntfs Journal size in MB" (REG_DWORD)

The number of changes that a given USN journal file can hold can be estimated by using the following formula: journal size /((60 bytes + (length of file name)) * 2)The number "2" in this formula stems from two journal entries for each file change: 1 for open and 1 for close. Divide the journal size by the size per change to determine the approximate number of changes that can occur before the journal wrap error is encountered. If we assume that the file names are in an "8.3" file format, this maps to approximately 200,000 files and/or directories for a 32-MB journal file. The number of changes would be less if long file names are used.

I had begun the migration tool and it found journal wrap. I had fixed the journal wrap but the tool still thought it was there. I stopped ntfrs then renamed jet then restarted ntfrs as you recommended.

If FRS is experiencing journal wrap errors on a DC, it cannot replicate files until the condition has been cleared. To fix journal wrap errors, you should perform a Non-Authoritative Restore based on the OS and SP.

The USN journal is a log of fixed size that records all changes that occur on NTFS 5.0-formatted partitions. NTFRS monitors the NTFS USN journal file for closed files in FRS replicated directories as long as FRS is running. Journal wrap errors occur if a sufficient number of changes that occur while FRS is turned off in such a way that the last USN change that FRS recorded during shutdown no longer exists in the USN journal during startup. The risk is that changes to files and folders for FRS replicated trees may have occurred while the service was turned off, and no record of the change exists in the USN journal. To guard against data inconsistency, FRS asserts into a journal wrap state. To perform maintenance on FRS replica set members, administrators may stop the FRS service for long periods of time. In this case, administrators may not realize the potential impact. Also, error conditions may cause the FRS service to shut down, and this causes a journal wrap error. In very large replica sets, replica members may encounter the following error during an authoritative restore (BURFLAGS=D4):

In these scenarios, the nonauthoritative restore process must be invoked manually. To do this, You must set BURFLAGS=D2 in the Windows NT registry. For Windows 2000 computers that use versions of the Ntfrs.exe file from Windows 2000 Service Pack 2 (SP2) or from Windows 2000 SP2 hotfix (WINSE 11773), the service performs a programmatic nonauthoritative restore when the journal_wrap_error is detected. By default, versions of the Ntfrs.exe file from Windows 2000 Service Pack 3 (SP3) and from Windows 2000 SP3 hotfix do not perform an automatic nonauthoritative restore (for example, SP3 leaves content in place as 2195 and SP1 left the context in place) when journal wrap errors are detected. SP3 versions of NTFRS may be configured to function like SP2 when the "Enable journal wrap automatic restore" registry entry is set to 1 in the following registry subkey:

FRS is a service that must always be running on Windows domain controllers and members of FRS-replicated DFS sets. If you increase the USN journal size, and therefore you increase the number of changes that the journal can hold before the journal "wraps," this reduces the possibility that the USN journal wrap will occur. The USN journal size can be changed by setting the following registry key:

journal size/((60 bytes + (length of file name)) * 2) The number "2" in this formula stems from two journal entries for each file change: 1 for open and 1 for close. Divide the journal size by the size per change to determine the approximate number of changes that can occur before the journal wrap error is encountered. If we assume that the file names are in an "8.3" file format, this maps to approximately 200,000 files and/or directories for a 32-MB journal file. The number of changes would be less if long file names are used. In Windows 2000 Service Pack 2, valid settings range between 8 and 128 MB, and the default is 32 MB. In Windows 2000 Service Pack 3, valid settings range between 4 and 10,000 MB, and the default is 512 MB. These settings apply to all volumes that host an FRS replica tree. As a guideline, Microsoft suggests that you configure 128 MB of journal for every 100,000 files that are managed by replication on that volume. 2ff7e9595c
