Transferring and Converting to AdvFS Existing Data File Systems

You can transfer existing data on any system that supports tar to Duix converting the file system to AdvFS.

Needs:

• Two systems: any system supporting the tar utility and Duix

Setups:

• Existing UFS configuration
  File system: /filter

• New AdvFS configuration
  File system: /filter
  Disk partition: /dev/rz26c
  Mount directory: /filter
  File domain: filt_domain
  Fileset: filter

Conversion procedure:

• Login to the system containing the orginal /filter file system and create a tar file on the default tape unit:
  # tar c /filter

• Login as root on the target system.
• Create a fileset in the filt_domain file domain
  # mkfset filt_domain filter

• Create mount-point directory and mount new fileset as follows:
  # mkdir /filter
# mount -t advfs filt_domain#filter /filter

• Restore the /filter file system from /dev/rmt0h (default tape) as follows:
  # mt rewind
# tar x /filter

• Edit /etc/fstab and add the following line to mount /filter as AdvFS
filt_domain#filter /filter advfs rw

• The filt_domain file domain now includes the converted file system and is ready to use.
