Can't Mount SYS because of BACKOUT.TTS.

The SYS volume will not mount .

The SYS volume appears to take a long time to mount while scanning BACKOUT.TTS.

High utilization during initial SYS volume mount.  

High disk activity on server


The TTS backout file has filled the SYS volume.

The BACKOUT.TTS file is invalid.

The BACKOUT.TTS file is so large it will take an unacceptable amount of time to backout these incomplete transactions.


Novell Possible Fixes                                        
1.  <JUST WAIT>  Most likely the file is just large and will eventually backout.  For very large files, this can take hours.  Backout transaction files could have grown to hundreds of megabytes, appropriately or inappropriately, and can take 3-5 hours to backout.  
2.  <RUN LATEST VREPAIR> to fix or delete a corrupt BACKOUT.TTS.  
Make sure you are using the latest VREPAIR program., Go to and check the appropriate version of NetWare to see what the latest available VREPAIR version.
3.  Use RCONSOLE to transfer a Zero byte BACKOUT.TTS from the workstation to the server.  You must rename the SYS volume first. Use INSTALL.NLM which is on the C:\NWSERVER to rename the SYS volume before mounting the volume.  Then LOAD REMOTE and RSPX.   This does require you to have at least two servers in the environment.  One to obtain the rconsole list from. This option will work every time if you do it properly.
4.  <REMOVE THE VOLUME>, reinstall NetWare and restore data from tape.  NOTE: For 4.1x systems, any attribute that references the file system of this server will be lost, ie, directory maps, print queues, etc.  If you are unsure of the ramifications of this action, contact the NDS team.  

Possible Third Party Fixes
1. <Delete BACKOUT.TTS with NWCC>  
Use NetWork Command Center,  JCMD or Vcopy to delete the file.
Search the web for NWCC or JCMD.  You can try to find the program.
Explode and read the documentation for its use.

This product can be loaded from the C: drive with SYS mounted as another name.
Follow these procedures:
1.) Start the server -ns.
2.) Enter a file server name and internal ipx number if prompted
3.) Load the disk driver.  Then load install.  If install is not present on the C: partition, you will have to get the program and load if from floppy or from the partition
4.) Rename SYS to something like SYSTEMP.  NOTE: The original NW4.11 INSTALL.NLM has a bug preventing
SYS from being renamed back to SYS once the volume name has been changed.  If the current service
pack is not installed, then extract INSTALL.NLM and INSTALL.MSG and copy them to c:\NWSERVER (or wherever server.exe is located.)  Once the SYS volume can mount, these files should also be copied to:
5.) Run NWCC or Vcopy
6.) Change the attributes of SYS:\BACKOUT.TTS to read/write. Note: jcmd will not change the attributes correctly.
8.) Rename SYSTEMP back to SYS.
9.) Down the server and restart.

For NetWare 6, use the NWCONFIG.NLM from NetWare 5.x.  This can be obtained from a support pack or from the NWSERVER directory from a NW 5.x server.  This should only be used to rename SYS.  The recommended way to do this is to put NWCONFIG.NLM on a floppy and load it from there by typing LOAD A:/NWCONFIG.NLM at the system console.  This will give you the functionality to rename SYS.  This will only work if SYS is a traditional volume.
