 Posted: Fri Oct 22, 2004 4:52 am Post subject: Has reiser4 been removed from kernel 2.6.9? |
 |
|
Recently I've emerged gentoo-dev-sources-2.6.9, willing to find there reiser4 built in. Suprisingly, there was no sign of reiser4 at all. I emerge development-sources to find out whether it's been removed or not, and I found there was no reiser4 in the original kernel either. Do you know by any chance why, or when (linking to changelogs is also OK)?
10x in advance |

It's in the -mm (unstable/testing) kernel patchset. The Gentoo kernel developers/maintainers have said they will not officially include Reiser4 support until it's in the vanilla 2.6 from Linus himself.

| Thanks for the answers. I think i'll go in for the -mm patchset, and if it's no good i'll check out 2.6.9-flapjack |

from the mailing list
| Hans Reiser wrote: | No distro using reiserfs V3 as the default is going to keep doing so
once reiser4 meets their stability requirements. Reiserfs is used by a
lot of people, and reiser4 obsoletes it, and the users know that. None
of the distros have expressed any intent of staying on V3, and they'd be
silly to do it. Many of them have expressed a desire to use reiser4.
Next year, indications are that reiser4 usage by distros as their
default will exceed that which is today possessed by V3. The higher
performance of V4 is going to increase our market share.
I would like to encourage its inclusion as an experimental filesystem
BEFORE vendors ship it. I think first putting experimental stuff in the
kernels used by hackers makes sense. I think it creates more of a community.
I'd like to point out that there is a lot of stuff in the kernel that is
a lot less stable than reiser4.
That said, inclusion in -mm found some bugs, and we are still testing
one of the fixes which was a bit deep. I want to finish that testing
(not more than 7 days) and send you all fixes before asking for inclusion.
Also, Hellwig made a valid point about getting rid of some macros that
reduce readability (I also hate code that prevents editors finding
called functions), and zam is working on fixing that.
Lindows is planning on shipping with reiser4 in its next release. I
would very much like to see our inclusion before that. |

|
|
when googling around for any sort of status of the efforts of Reiser4 being officially released in the vanilla kernel, I saw a lot of disturbing talk about not seeing Reiser4 for quite some time and perhaps even not in 2.6.
Can anyone confirm or deny this? 
As for chatter relating to the Reiser4 plugins and various migration tools (r3 -> r4) I couldn't seem to track anything remotely concrete down as far as deadlines or milestones.
This is one of those paradoxes I suppose where Reiser4 must be stable in order to be released, but must be widely tested on all the possible software combinations to be made stable. More specifically we have issues like Apache and NFS that don't play nicely with Reiser4 and will improve their support faster once it is declared "stable" as defined by the whole of the linux community.
Personally I recommend LVM and EVMS for efforts at using Reiser4. Given enough disk space at your location you can then more easily swap back and forth when problems arise. Examples are breaking off NFS mount points to separate logical partitions and then using another filesystem for that... same with areas serving files from Apache.
Hard drives are cheap(er) and this method more easily allows you to copy from the non Reiser4 partition to the new Reiser4 partition. Taring to temp location and then extracting to the Reiser4 partition is bad as the files are not restructured optimally. I have no idea of the effects of using cpio. |

Thank you for your input, good recommendations are always needed.
However, I personally tried the nitro and love sources for awhile and found them to be what they are... bleeding edge.
There are many problems with nicksched, 1G low mem patch, 4k mem block, and the as schedulers and finding the perfect combination takes some time. I realize btw that some of these are in other patchsets.
Nitro and Love pull some of the latest patches from all over, that means that these are not just fixes but feature addons. It is like repairing a hole on an aircraft wing while in flight and others are removing, adding, or modifying engines, compartments, stabilizers and cockpit interfaces. Meanwhile you have a pool of pilots that each fly differently.
Bleeding edge is just that and can't be beat for the bragging rights if that is your bag. I have often found that only bleeding edge solutions will allow me to solve actual stability problems in more stable versions so anything is possible.
btw, I am having mondo stability problems on nitro2 right now and am now passing the following params to the kernel (elevator=as acpi=off pci=noacpi). My hardware is different than yours and others (IBM 305's as well as one IBM ThinkCentre)
I could certainly do things on these computers that others would never find acceptable or stable. Isn't that the nature of bleeding edge? (note that no where did I say "good" or "bad" to nitro, love, or bleeding edge in general)

very nice, thanks Jake
perhaps I will just create an ebuild with a reiser4 use flag to make it easy for me. If that works then I suppose it wouldn't hurt to throw it in bugzilla. |
