Softupdates I believe are a little faster than journaling, but it's drawback is long disk checking after a dirty shutdown. I've never had a ufs specific issue in hundreds if not thousands of deployments, but nothing is guaranteed. ufs does have a great track records and bunch of service hours logged. > > Also if something goes wrong with the filesystem what are the tools to > check the drive and repair errors as in Linux I use e2fsck followed by > device ID. > Example after a dirty shutdown: fsck -y > In fact I am only really after ZFS for its self healing properties as I > don't mind going with any file system as long as it's stable. Ext3 although > easily repairable is quite unstable on my systems anyway! That's actually a bit disconcerting, do you have hardware instability? -- Adam Vande More
