And please tell me -- the point of journalling is to reduce fsck times upon failure - particularly important if you have 14TB of raid (yes, we had to fsck after a recent downtime, and it had been > 180 days - took half the day). What is the point of journalling if you have to compare and restore against backup everytime the power fails? This is slower than a mere fsckage. FYI, I think jfs has the same behaviour as xfs - I do notice a distinct lack of usage of a /lost+found, which has been important to me in the past. > ext3 remains the only journaling filesystem that I would, personally, > put any great degree of faith in, since it is still developed in a > cautious and safe fashion, and has a focus on getting the tools to > verify correctness in place before enabling kernel-side features. > > > Obviously, your millage may vary on these topics, as presumably have > your experiences. Sounds about right :) Next time I reformat/get a new drive, I'll be going back to ext3 - never caused any problems for me. -- TimC -- http://astronomy.swin.edu.au/staff/tconnors/ Single White Stick-Figure, L12, enjoys long walks by the shore, cooking up a nice menudo, and bashing small animals with sticks.
