Recently I read a lot about "new" file systems.
I checked some benchmarks that show MySQL working faster on EXT4 or XFS (and some other FS).
I also "found" that XFS and EXT4 are included in CentOS 5.X
However most of the articles I read speaks either very positively either very negatively on XFS. Same for EXT4.
Despite I have some Debian's that work on EXT4, I do not have experience with it.
Questions are - Is it safe?
If power stops - what will happen and what data could be lost?
If system crashes what will happen and what data could be lost?
If memory or some hardware (not the HDD controller or HDD) broke - what will happen and what data could be lost...
