[A51] TableConvert Offsets

Dear all,

While manually converting dlt files to idx and inx using:

./TableConvert di /media/tables/a51_table_100.dlt /media/GSM/100.ins:0
/media/GSM/100.idx

Do I keep the offset the same for all remaining files as well?

Example:

./TableConvert di /media/tables/a51_table_268.dlt /media/GSM/268.ins:0
/media/GSM/268.idx

OR

Does the offset (ins:0) change or increment in a pattern to ins:1 ins:2
.. etc. ?

Regards,
Spørgeren

The offset is meant to be used when you are converting multiple tables to raw device without filesystem.
You definitely want all tables to start at offset 0 when you have them in files.

Offset :1 would mean 4096 from the beginning, which makes no sense. If you were to put it to the device, you will have to see how many blocks were written and then set the offset to that (maybe +1). These offsets are expected to be around 10000000.

Thanks Jan.

Furthermore, could you tell me which of the following given below is the
correct format for tables.conf?

#Settings A:
#============================
Tables: /mnt/tables/gsm/100.ins 100 0
Tables: /mnt/tables/gsm/108.ins 108 0
.
.
Tables: /mnt/disk2/gsm/500.ins 500 0
#============================

OR

#Settings B:
#============================
Tables: /mnt/tables/gsm/100.ins 100 1
Tables: /mnt/tables/gsm/108.ins 108 1
.
.
Tables: /mnt/disk2/gsm/500.ins 500 1
#============================

OR

#Settings C:
#============================
Table: 0 100 0
Table: 1 108 0
Table: 2 116 0
.
.
Table: 39 500 0
#============================

Which one of the above has the correct syntax? A,B,C OR none !
Note that some of the tables are on a separate disk :(

I'm not sure about the "Table:" beginning of the line (maybe there is no prefix at all), but definitely the rest is
/mnt/tables/gsm/100.ins 100 0

Thanks again.

One final question:

/mnt/tables/gsm/100.ins 100 0
/mnt/tables/gsm/100.ins 108 0
.
.
.
/mnt/tables/gsm/100.ins 500 0

OR

/mnt/tables/gsm/100.ins 100 0
/mnt/tables/gsm/100.ins 108 1
.
.
.
/mnt/tables/gsm/100.ins 500 49

I think these are the start positions of independent files and not a raw
disk, so I guess the first option.. Correct?

Spørgeren

Yes, it's start position inside the file, so all are starting at the beginning - 0.

I tried these settings but still no luck :(

So I resorted to the standard method of writing the tables to a raw disk
and I realized that in the end the .idx files need to be in the same
directory as that of tables.conf

I wonder if that's the reason the independent files (.ins) weren't being
loaded.

Anyways, the generated/modified tables.conf has both Device: and
Table: sections.

---------
#Devices: dev/node max_tables
Device: /dev/sdc1 40

#Tables: dev id(advance) offset
Table: 0 132 5116XXXX
Table: 0 324 23540XXXX
Table: 0 364 28656XXXX
------------
where
XXXX are actually some numbers.

So I guess even when we use the .ins files we might need to have
tables.conf like

---------
#Devices: dev/node max_tables
Device: /mnt/tables 40

#Tables: dev id(advance) offset
Table: /mnt/tables/gsm/100.ins 100 0
Table: /mnt/tables/gsm/108.ins 108 0
Table: /mnt/tables/gsm/116.ins 116 0
------------

with the .idx files in the same directory as tables.conf.. or having
tables.conf in the directory of the idx and ins files.. Not sure if the
Device parameter will still be needed.

I have now written the tables (.dlt) using Behemoth.py directly to a
disk.
Thanks for all the help.

Spørgeren
