Abel Coto's questions

I have been investigating a bit previously to install Centos 5 in a box that it will use applications managing large files (i think more than 300 MB minimal).

I was thinking in , as / has a lot of small files, it would be better use ext3 instead xfs , and use only xfs in /home.

But i don't know if use xfs in / could give some increased performance to the applications that will be used there.

As those apps use large files i think perhaps , have / as xfs could benefit those apps when running them.

The data will be in /home,but as the apps would be installed in / , and perhaps as they manage large files , having also / as xfs could be good.

PD: I know that in centos 5 , anaconda doesn't let to format a partition in xfs, but once installed,installing first a new kernel supporting xfs , and installing xfsprogs, i can use a live-cd and with rsync backup / and /home to another disk , format partitions to xfs and then restore backup.

What do you think about using xfs for / in this case?

I have been having some electrical issues,mostly power going out suddenly for a few months,and although ups solve the thing mostly.

But still i am worried about filesystem corruption,and data lost.

It is xfs worse than ext3 or less reliable when the computer goes off,or crashes or other filesystem issues?

Having a ups and a good backup strategy (i have a 1,5 tb disk that i want to use to backup all the critical data) is enough ,and i shouldn't be worried ?

I have been reading that xfs zero out data (although i think this has been solved) when the power goes off ,and things like that XFS is not safe against data corruption.

Enabling write barriers and tweaking xfs correctly, and having a ups and backups , could be xfs as reliable as ext3, or at least acceptable enough?

If i use xfs for / and /home to have more performance (with large files mostly), I will risk more my data,than using xfs?
