I've read the features and it looks very good. Can i install that in my system ? I have mandrake 9.0 and Windows XP run on PC 1.5G cpu.

Thanks

Does anybody have experience changing filesystems?

Sneeze:
Yes you can, in fact, during your Mandrake install, you even have that as an option should you choose it (advanced install).

You shouldn't hijack threads, at least not until an answer has been given to the original poster. Instead you'd be better off starting your own, this will not only give your more direct answers, but more answers all together since most people will view this thread to answer sneeze's question.

But yes, I've changed filesystems. Unless you are going from ext2 to ext3 or back, then you will lose your data (likely) so a backup is a must. Then it's just a matter of:
mkfs
Each filesystem supported by your version of mkfs can be called by it's type, but read the man page for more info:
man mkfs

Kernel support is also a must, but as I mentioned, Mandrake definitely has it in the default kernel.

Cool

I use it only on my secondary hard drive. I format it as xfs instead of converting it from another filesystem. I'm thinking on converting my / (everything except /home) to xfs, but I rather just format that entire partition instead of converting. Of course that I'm going to make either an image file of it or use a good copy utility. Though, I don't know what day or month that I will do it.

XFS is great if you have a 64 bit processsor, but today's processors (32 bit) can only handle 4 gigabytes. Soon the Athlon 64 or Optron will be out and this filesystem will be worth it. Another great feature that XFS has is it can handle a million files or more in a directory with out a performance penalty. I'm using Mandrake's XFS rpm packages, so I don't know if they used the right compiler to take advantage of this 64 bit filesystem.

Overall I don't have any problems.
