Re: [ubuntu-in] Which is the best filesystem to use??

Hi Kingsly,
Tricky question. People would swear by a file system as ideal. I have 
read that ext4 has zero tolerance for powerouts and much greater chance 
of it being corrupted in such circumstances, so it is out of question 
for people like me.
    

Choosing a filesystem because it's "power outage resistant" is not logical at
all.  No file system is geared for power outages which is a physical failure. 
So singling out ext4 is bad because you can suffer just as bad a corruption
on a power outage on any filessytem.
Sure, I understand that. I have never said that ext4 is bad. In fact, what is bad is that I can not use it. Would you point out where I have said ext4 is bad?
An OS crash is a software event and filessytems can be geared to deal with
it, whereas a power outage is physical event and there is no way for software
to deal with it.
Agreed. I have no issues here.
That's why you have things like UPS to ensure that your system goes for a
clean halt/suspend during a power outage.
Very true. And in addition to the UPS, I have solar energy and a windturbine providing me backups. However, in spite of these, power can fail. And does fail once in a year or some times more frequently. Perhaps that is not an issue for you, but it is for me. And so I remain with ext3, and yes, I do realise that this also may fail some time and I might loose data...
