you are just lucky.
before i would start using anything new in such important part as
filesystem, i do extreme test, ssimulate hardware faults, random
I did it for ZFS not once, and it fails miserably ending with
unrecoverable filesystem that - at best - is without data in some
subdirectory. at worst - that crashes at mount and are inaccessible
under FFS the worst thing i can get is loss of overwritten data only.
overwritten inode - lost file. overwrite data blocks - overwritten files.
what i don't talk about is ZFS performance which is just terribly bad,
except some few special cases when it is slightly faster than
It is even worse with RAID-5 style layout which ZFS do "better" with
Better=random read performance of single drive.
