Formating options for large partition/files

Formating options for large partition/files

[Cédric Lemarchand]

I plane to use XFS on a >50TB partition, that will host a few big
(backup/archives) files. Reading the chapter 4 of the online
documentation, I find 2 formating options that could fit :

- max out the allocation block : -b size= 64KB
- max out the sector size : -s size=32KB

I am not an expert, so any light will be appreciated.

Cheers,

Cédric

Replaying to myself, it seems default values will cover all my needs :

- blocksize = 4k (max value for adm64 arch)
- sector size = 512 ( hard drives are virtual, so not 4k)

Any advices on mount options ?

Cheers
