Hello,

I use the following configuration for my firebird data partition:

ext3/dm-crypt/HW RAID with battery puffer (HP ProLiant DL320 G6)

What have I to do, that I have in nearly all cases consistent data after a power failure?

Is is it necessary to mount the ext3 portion with the option barrier=1?
What is the optimal ext3 journal mode for my requirements?

Did the dm-crypt need special options?

I think using the hardware raid write cache is no problem, if the power fails it is saved by the battery puffer. Is this correct? What are your experience?

Are there more problems (problematic caches)?

Thank you for your answers.

Thomas
