| Yea, I think reiserfs is better when it comes to handling a lot of small files. |

/agree
XFS is good for a lot of really big files.

I currently have a partition for "/" and "/home". I recently copied "/" from reiserfs to ext3 and the disk usage went from 12 GB to just over 13 GB. So reiserfs seems well suited for storing many large files.
The reason I went from reiserfs to ext3 is because I've had problems with reiserfs in the past, and now there's reiser4, which I'm sure will have bugs. If you want to be 100% sure of avoiding headaches in the future, I'd stick with good ol' ext3. |

Probably becuase Resier uses a smaller default block size (1024 or 512, iirc) than ext3 (4096 bytes), so even if a file or inode is smaller than 4K, it still uses up that entire block...I hope I make sense...

Actually, the best FS for /usr/portage is Reiser4. Lightning fast.
Yes, I know that Reiser4 isn't really stable yet - but consider this. Its /usr/portage.
`emerge sync` and its back there in all its glory. Stability is pretty much a moot point here. |

did think about reieser4 and as it will have own partition it does not really matter if it does dies, though as i am trying to get this and couple of other partition running on raid5 via evms i am not sure if reiserfs will work.
Just thinking though, could set /usr/portage as raid 0 which would also make it faster

I don't think reiserfs on raid0/1/5 will be a problem. I'm using it for long on a raid1 device.. Theoretically of course, software raid should work with any filesystem..
Getting on new Reiser4.. From what I read, it's faster than the current Reiserfs but it also uses more cpu because of the advanced algorithms that are used.. So if you are going to use software raid and Reiser4 together, have a look at your cpu with the highest datarates. I guess a slowdown through cpu is not impossible, of course depending very much on you PC..
Anyway, if you don't care about the data and a possible loss, Hans Reiser might be very thankful for you to try it (and to send bug reports if it doesn't work out)

edit: I just notice your posting isn't that fresh.. Have you tried it yet? |

I've been using reiser4 since March (2.6.4-love3) with no problems, and a month or so ago I moved /usr/portage from xfs to reiser4, works fine and a bit faster, too  ...

Cryptic ? You asked a question, I posted an answer, I don't see anything cryptic about that. |

Why's that cryptic? Its a filesystem that would make a good choice. Assuming you have lots of RAM, and arn't bothered about rebuilding your portage tree from scratch every time you reboot.

So how to move from a "normal" reiser filesystem to a new reiser4?

Copy the data, wipe the partition, create the reiser4 partition, move the data back.
Only way AFAIK.
Since it's /usr/portage, I'd just copy the distfiles elsewhere, if your bothered about them that is.
Going back to Genone's post, I assume it's possible to have mount points withing a tempfs.
I.e. keep /usr/portage on tempfs and /usr/portage/distfiles on say reiser?
That would be quite nice.

As you are Gentoo god (dev) it may not be but for a mere mortal it is, i have seen this tmpfs in fstab and thought it was a tempory filesystem but never thought it could be used for anything such as portage!!
A little more info with your post as to why it would be best may have been more helpful.
Thanks for your post though,

| If you put your whole portage treen in tmpfs, won't you lose it when you reboot? |

yes, but at least you know that it will be gone (compared to the uncertain state with reiser4). Also if it's a server (or in general isn't rebooted regulary) it doesn't matter. And finally you can always recreate it without problems (put `emerge sync` or something similar in local.start).
Point is: there is no "best" filesystem, it all depends on your needs and environment. |
