Using iXOS-JUKEMAN
iXOS-JUKEMAN 2.2 User Manual Pre.12/97160
4.12.4 WORM file system
Note: The WORM file system is for system integrators. End users
should configure and use it with special care.
The WORM file system is a special file system implementation to write
WORMs, MOs, and PDs (but not CD-Rs) incrementally and more efi-
iciently. Compared to the IFS, files are written directly to the disks so
there is not need to issue a cdadm writer flush command. Please
note that disks written with the current version of the WORM file system
can be read by iXOS-JUKEMAN only. It will be possible with a later ver-
sion of iXOS-JUKEMAN however, to finalize these disks to ISO 9660.
To use the WORM file system enter a section similar to the following in
the file server.cfg:
ixworm {
maxOpenDatafiles { 10 }
numInodes { 250000 }
rehashWarning { 20 }
HWerrorLog { d:\temp\hw_errors.txt }
DataFilePath { e:\testdata }
ixwhashdir {
nodesize { 4 }
files { file1 }
file1 {
path { c:\temp\hashdi1 }
size { 50 }
mode { mapped }
}
}
ixwhashname {
nodesize { 4 }
files { file1 }
file1 {
path { e:\testdata\hashname }
size { 50 }
mode { mapped }
}
}
ixwhashfile {
nodesize { 4 }
files { file1 }
file1 {
path { e:\testdata\hashfile }
size { 50 }
mode { mapped }
}
