Hello!
So far I got 5 replies, but no answers. So, I'll try again... does
anybody know what the wikipedia articles are talking about in terms of
those data loss scenarios with ext3 and ext4? And more importantly,
which one I should use (to be safest) and how should I set up those?
All insight and help regarding ext3/4 setup is greatly appreciated.
Thanks,
HG

Still, there is a data disk that should be kept alive... what is the safest way to go? I was initially thinking about ext3 + full journal of data and metadata. However, according to Wikipedia, this isn't safe from crash (http://en.wikipedia.org/wiki/Ext3#No_checksumming_in_journal). However, it says that: "The ext3 barrier option is not enabled by default on almost all popular Linux distributions[citation needed] except openSUSE" Is this true (11.1)? And what does it mean and how do I check it? At least I didn't see the mentioned "barrier=1" in YaST - Partitioner.
Wikipedia then mentiones that ext4 is released and that it is to fix this thing. However, again according to wikipedia (http://en.wikipedia.org/wiki/Ext4#Caveats) it again has different, but similar problems. Of course, with ext4 I would use the same journaling.
So, what to choose and how to set up? Disk/Partition is 2Tb. The data will be mainly large photographs (RAW) and video files. Performance is important, but safety during power outages is more important. Separate system drive (Ext3).
