Creating a larger FFS for MachTen or Codebuilder

Description

This paper gives the steps needed to move the MachTen or CodeBuilder system into a larger fast File System (FFS) without creating a large tar image in the process. Once the new FFS is created, a tar process will pipe all files to an untar process working on the larger FFS.

Overview of the steps

In step 1 a new, larger FFS is created. Step 2 mounts this new FFS in a safe area (/mnt). Step 3 creates a list of directories that should be excluded from the tar process. Volumes that may cause problems are un-mounted in step 4. Step 5 is the tar-untar process. In step 6 the old, smaller FFS is renamed on the Mac side and the new one is gives it's name. Step 7 removed the old FFS from your volume, freeing up the disk space.

Note: If you have MachTen instead of Codebuilder, substitute MachTen and the appropriate version number for the occurances of CodeBuilder.

Step-by-step instructions

1. Create the new, larger FFS

   	newfsf -s <size> <path>/<newFFSName>
   		
   		<size> = 1024 x 2 x (size in MB of new FFS)
   			eg. for 180 MB FFS 1024 x 2 x 180 = 368640
   		<path> where the FFS will be created.  In the CB folder is the best place
   			eg. //"CodeBuilder v1.1" would be the  for CodeBuilder 1.1.
   		<newFFSName> = name of FFS as seen from the Mac
   

2. Mount the new FFS in Codebuilder (or MachTen)

   	mount -t ffs <path>/<newFFSName> <mountPoint>
   	
   		<path> where the FFS was created in step 1
   			eg. //"CodeBuilder v1.1" would be the <path> for CB 1.1.
   		<newFFSName> = name of FFS as seen from the Mac
   		
   		<mountPoint> = where CB will mount the new FFS
   			eg. /mnt is recommended
   

3. Create the tar exception list

   	cd /hfs
   	vi except_list
   	add the following lines to this new file:
   	
   		CodeBuilder_Folder/*
   		mnt/*
   		bootvol/*
   		hfs/*
   		volume/*
   

4. Unmount other volumes

   	mount
   	
   	Only the following mounts sould remain:
   	
   		o //CodeBuilder v1.0/CodeBuilder_FFS on / (local)
   		o <CBVol> on // (local, NFS exported)
   			where  is the Mac volume that CodeBuilder is installed
   		o <MacBootVol> on /bootvol (local)
   			where <MacBootVol> is the Mac volume that contains the System Folder
   		o //CodeBuilder v1.0/newffs on /mnt (local)       
   			this is the new ffs you just created in step 1 and mounted in step 2
   		
   	All other volumes are to be unmounted using:
   		umount <VolName>
   			eg: umount /"CodeBuilder v1.0"/X11R6_FFS if you have X11R6 mounted
   

5. Preform tar to new FFS

   	cd /
   	tar -X /hfs/except_list -cf - . | (cd /mnt; tar xvfp -)
   	
   	After a long time, the prompt will return and the process will be complete
   

6. Renaming the FFS

   	Quit CodeBuilder
   	Rename the CodeBuilder_FFS to CodeBuilder_FFSOLD
   	Rename the  to CodeBuilder_FFS
   	Start CodeBuilder
   

7. Remove the old, smaller FFS

   When you are sure that everything was transfered to the new FFS, drag CodeBuilder_FFSOLD to the trash and empty.
