There's literary a _bunch_ of threads about this. And a lot of people are already using it as their main filesystem. I did as well. Until a couple a weeks ago when I re-bootstrapped my computer and changed the whole shebang to xfs. Just to try it. I had only positive experiences with Reiser4 though. Especielly when dealing with many small files (emerge sync).

hehe, just did. Shame the search is so crap though ;(
Got some good stuff. Looks like I have to backup my data then restore it when the disk is formated. Any advice as to the best method for this?
Also, I cant find where in the kernel I enable reiser4?
Thanks guys...

Hmm, I agree with you on the search engine here 
Anyway, how I did it - relatively quick and easy:
get a new partition, big enough for the data to be copied to (don't laugh, I know someone who tried to back up his 6G root partition onto a 2G one and wondered why it didn't workl)
boot into a reiser4 live cd (try redeeman's one - search for it  )
mount root and backup partitions
cp -a root > backup
format root to reiser4
cp -a backup > root
edit fstab (!!!!)
reboot
That's it really. It can take a while for the physical copying process to be done but it is easy and painless (well, it was for me).
Obviously, you can tar the root partition and this and that, but I actually found it a lot quicker to do a simple cp -a. You are not going to sending it to anyone so just do it the easy way. (The -a option on the cp command keeps the permissions intact).

Ok, im with u. Thanks
>>cp -a root > backup
That dont work though, i just tried it, it's missing a destination ?
Would cp -a / /freshpartition/ not be the way?
and where is the kernel is reiser4 enabled? I dont see it under Filesystems ---> ??
thanks again

Sorry, they were not meant to be actual commands 
With cp -a root > backup I was implying copy (with the -a option) your root partition to your backup partition
You must boot into a livecd to do this copy process, you cannot copy a running root partition as it will go into an endless loop as it copies the proc directory (as the proc directory will change everytime something happens, i.e. when you copy something).
The actual copy command is: | Code: | | cp -a /a_partition/* /other_partition |
For the reiser4 filesystem, you need a resier4 kernel.
Reiser4 is still considered to be in a testing phase (and quite rightly IMO) and is not in the standard kernel.
Love, nitro and I think xx sources have reiser4 in it.
You must have the reiser4 livecd as well or you won't be able to format your root partion (once copied) to resier4.
You will need to provide specific system info and what you have done (with what livecd, etc) for more specific help. |

Ahh... then I may wait till gentoo-dev-sources feature it. I like to have my kernel in portage ,)
This thread will hardly go to waste though, im really looking forward to reiser4 and will come back when I eventually do it
much thanks for all your help, really appreciated!

Not a bad idea, I had it on my root partition and lost 30G of info from it.
I have it on a spare partition now just to test it and, as can be seen from many, many, many posts on the love and nitro threads, reiser4 has a way to go before it is stable enough for production use.
I find it even funnier that one of the main walking adverts for reiser4 (no names), who says go for it, it's great, etc doesn't use it on his root partition 
I'll wait until it is integrated into the standard kernel before trying it again on a large scale.
Anyway, good luck. |

I was just wondering, wheter I gotta
do this as root or as a normal user when I wanna backup my home partition? When I copy the the whole directory back to the old one doing so as root, will the permissions be set right?

The permissions will be the same if you copy your home directory as root with the -a option, but the owner might have changed. (I can't be absolutely certain, I think it had changed owners on mine but definitely not permission)
If you want to make sure, copy it (as root if you like), do your stuff, copy it back as root and then issue the following command:
| Code: | | chown -R onion: /home/onion |
Obviously, change the first onion to your user name and the second onion to your home directory (which should be the same as your username anyway). The -R option ensures it is a recursive change so all directories and files in /home/onion are changed to onion ownership.
That's what I do.
