How can I use BD-RE with UFS on geli?

[SAITOU Toshihide]

I tried BD-RE with UFS on geli but didn't success.
What was wrong the below?


* BDR-S03J, Pioneer SATAT BD/DVD/CD Writer
* FreeBSD 7-STABLE (Apr. 5)

1. when insert BD-RE:

   [/var/log/messages]
   acd0: FAILURE - READ_TOC ILLEGAL REQUEST asc=0x24 ascq=0x00 
   (cd0:ata6:0:0:0): READ TOC/PMA/ATIP. CDB: 43 0 0 0 0 0 0 0 4 0 
   (cd0:ata6:0:0:0): CAM Status: SCSI Status Error
   (cd0:ata6:0:0:0): SCSI Status: Check Condition

   (cd0:ata6:0:0:0): Invalid field in CDB
   (cd0:ata6:0:0:0): Unretryable error


2. maybe the diskinfo is wrong. (READ_TOC ILLEGAL REQUEST is related?)

   # diskinfo -v /dev/acd0
   /dev/acd0
           2048            # sectorsize
           8796093020160   # mediasize in bytes (8.0T)
           4294967295      # mediasize in sectors


3. trying disk format with dvd+rw-format was failed.

   # dvd+rw-format /dev/cd0
   * BD/DVD±RW/-RAM format utility by <appro at fy.chalmers.se>, version 7.1.
   * 25.0GB BD media detected.
   * formatting 63.9%

4. but after the above, the diskinfo is something sane:

   # diskinfo -v /dev/acd0
   /dev/acd0
           2048            # sectorsize
           24220008448     # mediasize in bytes (23G)
           11826176        # mediasize in sectors


5. so I tried geli init

   # geli init /dev/acd0
   # geli attach /dev/acd0

   GEOM_ELI: Device acd0.eli created.
   GEOM_ELI: Encryption: AES-CBC 128
   GEOM_ELI:     Crypto: software


6. then newfs:

   # newfs /dev/acd0.eli 
   /dev/acd0.eli: 23098.0MB (47304700 sectors) block size 16384, fragment size 2048
   	using 126 cylinder groups of 183.77MB, 11761 blks, 23552 inodes.

   [/var/log/messages]
   acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05 
   GEOM_ELI: g_eli_read_done() failed acd0.eli[READ(offset=65536, length=2048)]

   * this was not always seen and the offset or the lenth is
     random during my trial.


After this I can mount /dev/acd0.eli but the programs which
access to this disk frequently abort with these log messages:


   acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05 
   GEOM_ELI: g_eli_read_done() failed acd0.eli[READ(offset=11946934272, length=2048)]
   g_vfs_done():label/DailyBackup[READ(offset=11946934272, length=2048)]error = 5

   acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05 
   GEOM_ELI: g_eli_read_done() failed acd0.eli[READ(offset=2697789440, length=16384)]
   g_vfs_done():label/DailyBackup[READ(offset=2697789440, length=16384)]error = 5

   acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05 
   GEOM_ELI: g_eli_read_done() failed acd0.eli[READ(offset=11946934272, length=2048)]
   g_vfs_done():label/DailyBackup[READ(offset=11946934272, length=2048)]error = 5

I feel the disk access sometimes goes over the disk area
because of the incorrect disk parameters.

Thank you.
