Hi,
I'm planning to build a rig like mine for my brother before to long. I
know there are lots of opinions on the net but want some personal
experience information on this. My brother does not have a UPS. I may
can talk him into getting one but not sure. What is a good file system
that recovers well from a improper shutdown? I use ext2, ext3 and
reiserfs here but never had a power problem, except when hal broke my
stuff. I know XFS is not good for this already from my own personal
experience.
Does anyone here have any personal experience on this? Just a 'I use
this and had a power failure and it powered up fine with no data loss'
would be nice. If this happened a lot and still worked, that would be
even better.
I'm not looking to start a turf war. This will be a plain old desktop
so it doesn't need a fancy file system, just one that recovers from a
power failure.
Down here we have Africa power.
Africa power makes post-Katrina power look tame.
Total corruptions in 5 years with reiserfs-3.6 and NO ups in that environment
= zero.
I can't fairly comment on ext[234] as I don't have the same length of
experience with them. From what other commentators have said elsewhere it
looks like with optimum settings and tweaks they can be just as good as I got
from reiser, but that's just hearsay from me.
My gut feel on this is that any modern fs will be built to be able to tolerate
blackouts - it's almost a requirement these days. So it's likely a 6 and half-
dozen question in reality. Except XFS as you know, but that's a special case
(aggressive caching virtually requires a UPS or guaranteed no-downtime power)
I have /boot on ext2. Portage is on ext3. I have reiserfs on
everything else. I did have the hal problem and a power supply fan that
died and I had to pull the plug. All the file systems I use recovered
nicely after those problems. I didn't lose anything that I know of.
Is reiserfs being maintained anymore? I have read where some say it is
not but I have also read they are working on version 4 and it is being
maintained. Not sure what to believe on this one.
Thanks.
Dale
