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
real 18m58.580s
user 0m15.348s
sys 0m29.028s
# time lz4c -d /dev/dvd decompress
Error 67 : Unfinished stream
real 0m3.285s
user 0m0.000s
sys 0m0.000s
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.
