The File Replication Service has detected that the replica set "%1" is in JRNL_WRAP_ERROR. Replica set name is: "%1" Replica root path is: "%2" Replica root volume is: "%3" 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 "%3" has been formatted. [2] The NTFS USN journal on volume "%3" has been deleted. [3] The NTFS USN journal on volume "%3" 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 "%3". Following recovery steps will be taken to automatically recover from this error state. [1] At the first poll, which will occur in %4 minutes, this computer will be deleted from the replica set. [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.
