Is ZFS production ready?

UFS2 is here since IMHO year 2005.

Now the only problem is fsck time.

actually IMHO fsck can be improved a lot but someone must have time and 
will to do this. if parallelism would be exploited on gstripe type(*) 
volumes then it should take less than 30 minutes no matter how large the volume 
is.


Anyway - even with UFS which is the most fault-resilent filesystem i know 
- i would not recommend creating gstripe type volumes taking too many 
disks for the reason i already explained.

For now softupdates+journal is fine, you actually have to do full fsck now 
and then, but at spare time.

*) gstripe type means gstripe, gstripe+gmirror, graid5, graid5+gstripe, 
hardware matrix controller with any type of RAID configuration.
