Choosing the type of file system on Linux: if you have any doubt ...
Hi all, It is under the threatening sky that I take my pen to dig into a test I have wanted to remake for some time:
That is the impact of the choice of the type of file system on which to implement your chunks for Informix Dynamic Server on Linux.
As you probably know, raw devices have for some time been considered obsolete technology on most Linux distributions. It is typical of the conflict of interest between database vendors who advocate its use, and the editors of the OS and hardware manufacturers who go in the opposite direction.
How to implement chunks in IDS is not without effect, insofar as it directly affects the performance of input-output, and so the overall performance of the Informix server. As a reminder, it's always good to divide up the data on the maximum number of disks, and to mirror the physical devices. That's why it is better to create the chunks on disks configured with some redundancy (ex: RAID 0/1, RAID 5, journaled file system, etc. ..), but there are costs in terms performan...
