Just image,there are two machines which are connected to each other through network device. One is install RH9.0, and the other is SuSE 9.0 which used reiserfs formation.

If data are transferring from RH9.0 machine to SuSE by NFS service, it also means copying ext2 to reiserfs formations.

As we all know, reiserfs has log information acts more powerful than ext2, so I think reiserfs has larger storage space than ext2.

The question is, what's happening when transfer between ext2 and reiserfs? Does the data file in ext2 be re-written to reiserfs formation?


Thanks.

It only sees it as a file. It doesn't matter what file system that are used. It will place the files on the drive and add any information that it needs to for reiserfs. The same can be said if you were copying from reiserfs to ext2. It would just place the files on the drive without the extra information.

It will be fine to just copy it over. I have never heard of it causing any trouble and don't see how it could really. This would not work if you were using dd though.

Does that help?

Thank you,Dalek.
I've ever heard of that copy files from Linux(ext2) to MS-Windows directory(NTFS) through smb service, it could be atteched more extra information, does this matter the data integration?

Permissions and ownerships differ, nothing else. Those aren't kept IN
the file, though, but in a separate area of the file-system. As far as
the file-content goes, this is completely file-system and transport
agnostic. There's no piece of ext2 coming to your reiser partition,
and NTFS won't pollute ext2.

That's what I was trying to say. Thanks. Me tongue was tied. O_O

Hmmm,I see.
It's very kind of you, Tink and Dalek.
Thanks a lot.
