[Bug-xorriso] How to write 27G file to BD-R DL

[Andrew Fraser]

This is a request for help, not a bug report.  Please pardon me and let
me know if this is an inappropriate use of the list.

I have a single compressed file from a zfs snapshot that I want to write
to a double sided Blu-Ray disc.

Please recommend a command line call that will write the data.

Here is the file size:

->ls -l check_size.lz 
-rw-r--r-- 1 root root 28927582844 Dec 19 08:52 check_size.lz

Here are the xorriso and lz4c commands that I tried:

# time xorriso -as cdrecord -v dev=/dev/dvdrw blank=as_needed 
/mnt/big/check_size.lz 


xorriso : UPDATE : Closing track/session. Working since 1128 seconds
xorriso : UPDATE : Closing track/session. Working since 1129 seconds
Writing to '/dev/dvdrw' completed successfully.

xorriso : NOTE : Re-assessing -outdev '/dev/dvdrw'  ('/dev/sr0')
xorriso : NOTE : Disc status unsuitable for writing
Drive current: -outdev '/dev/dvdrw'
Media current: BD-R sequential recording
Media status : is written , is closed
Media summary: 1 session, 14124960 data blocks, 26.9g data,     0 free

# time lz4c -d /dev/dvd decompress

Error 67 : Unfinished stream

I've failed three times with growisofs.  I used slightly different
options each time, but I get the same final message.  EG:

# growisofs -speed=1 -Z /dev/dvd=/mnt/big/check_size.lz

Thanks for any advice.
