TITLE : Howto make a read only filesystem on a floppy diskette. OS LEVEL : AIX DATE : 17/01/99 VERSION : 1.0 ---------------------------------------------------------------------------- You can build a filesystem on a floppy and mount it, however the filesystem will be read only. The reason that the filesystem will be read only is because AIX cannot create a journal log on a diskette. The intended use is for temporary access to read only data. The diskette file system must be unmounted after use and during system backup procedures or errors could occur. To make the read only filesystem on a floppy: 1. Make a subdirectory on an existing filesystem and place all of the files that the diskette will contain into this subdirectory. 2. Enter the following command to create a prototype file containing information about the new filesystem, in the example /dir_struct is the pathname of the subdirectory created in step 1, and proto_filename is the name of the prototype file to be created. proto /dir_struct > proto_filename 3. Place a formatted floppy into the drive. 4. Edit the prototype file and replace the first line with the following: 0 0 5. Enter the following command to make the filesystem on your floppy: mkfs -p proto_filename -V jfs /dev/fd0 6. Create the directory upon which you will mount the floppy based filesystem, or you can use /mnt. Mount the filesystem: mount -r -V jfs /dev/fd0 /your_mount_point 7. To unmount the filesystem: umount /dev/fd0
