You should use a simpl data path and create a separate tablespace for each
InnoDB file
innodb_data_file_path=ibdata1:10M:autoextend
innodb_file_per_table
This way, ibdata1 only contains the metadata and MVCC control data for all
InnoDB files and transactions

Dear all,
I have doubt regarding the storage structure for Innodb files :
Our database server has the following paths :
/dev/sda5 69G 35G 32G52% /hdd1-1
/dev/sdb1 274G 225G 36G 87% /hdd2-1
/dev/sdc5 274G 225G 36G 87% /hdd3-1
/dev/sdd5
ing those takes more time than restoring the datafile.
That being said, I don't know wether InnoDB files don't get updated metadata
even if no DML happens in them.

There is if you're doing incremental back-ups, in which case adding one byte to
that file costs you 50GB of backup space.

When you activate it, the db will keep reading and using your existing

Converting your existing tables is done table per table us
Hi Vokern,
On a running MySQL Server enabling *innodb_file_per_table* makes no changes
to the existing tables. The newly created table (innodb) will be affected
and have thier own .ibd and .frm tables.
Although, you can enable smoothly. But it's better to have it from scratch.
So, that you can re

That's a very good point, actually, as that will also immediately free the
space from tables you delete.
My instincts say that it's marginally slower, though; although honestly I
don't have any data to support that. Does anyone have benchmarks about that
?

I suggest to have a single ibdata1 file and use *innodb_file_per_table* to

You have to round the size of the last data file (ibdata4) and add the
new ones.
You can find more information on the manual:

Hello,
Currently I have the setting:
innodb_data_file_path=ibdata1:10G;ibdata2:10G;ibdata3:10G;ibdata4:10G:autoextend
Because the last file of ibdata4 is very large (more than 50G), if I
want extend the data to more files, for example, ibdata5, ibdata6...
how to do it?
Thanks!

Well, you're going to need to state how big a record is, what OS
platform you're using, what MySQL version you're using, and exactly
what error message you get when you're trying to insert that 5th
record.
Your my.cnf would help, too.

In my opinion, if you're unable to put InnoDB files on different disks
there is no sense to use separate files. Even more - using the raw
