no, you'll have to reformat. luckily i just ran out of room and want to change my partitions anyway! hopefully this will be merged soon into gentoo-dev-sources |
Not exacly a Filesystems kind of guy, but isn't this something relevant?

i was taking a look at the mm4 sources, but all i see in the kernel menu is ReiserFS. i thought it would say something different for reiser3/reiser4. is this in fact reiser4? because i see a reiserfs and reiser4 directory in the kernel's fs/ dir, leading me to believe this is just v3. _________________ -Tristan |

The last time I converted to a new filesystem, I booted off of the livecd, created a partition the size of the old partition, copied the data from the old partition to the new partition, reformated the old partition, and copied the data back. I know that the last 2 steps are probably unneeded, but anyway . What I want to know is where can I get a livecd that supports the reiser4 filesystem?
[EDIT]: Yay, tux's little helper. |

Wouldn't it be an older version? I mean, it wasn't released (and therefore I assuming, completed) until just recently. I wouldn't want to be using an old Beta version with old bugs in it. I'd want to create and use the partition with the newest patch. |

I've been using reiser4 for all of my partitions (exept /boot) since redeemans first r4 livecd. Most of the time it _was_ stable for me, and of course fast.
But there was a time when noone used to patch it for their kernels, and I tried patching myself, had some crushes and stuff like that. I tought getting back to reiser3 but now I am glad I didn't the move. |

gah. well i looked everywhere for the 4k stacks option, and found it nowhere. i finally just thought to grep STACK .config, and commented out the CONFIG_4KSTACKS=y option. *shrug* works great now. _________________ -Tristan |

But if I want to do a new gentoo install, with my first partitons as Reiser4, I need to wait for a 2.6.8.1-mm2(+or higher) LiveCD right? |

reiser4 is complatible with all of your software(except fs specific stuff like fsck.ext2 of course)
apache runs great on reiser4, especially when serving up a lot of very small files or using dynamic content and having frequent disk writes of small amounts of data.
--
also, reiser4 is perfect for removable disks because of the atomic writes, so if your external drive loses power in the middle of a copy, no problem, no lost file and no lost data whatsoever(unless the disk actually fails)
--
reiser4 is GOOD
--
for those who are weary of trying reiser4, just make an empty disk image using loopback and format it reiser4, and then mount it and copy your system over if you have the spare space. then add a root=/dev/hdx/pathtoimage/reiser4image.disk to your kernel boot params in grub/lilo, then you can check it out without risking your current system. |

i'm using reiser4 for / /home /lib /var /tmp /etc /usr, but not /boot
i have noticed a good speed increase in rsyncs, seems a lot of the bottleneck makeing rsyncs slow is not my net connection(3Mbit cable) but I/O speed on my disks. noticed a %25 improvement in time vs reiserfsv3 in rsync as measured buy a wall clock. i haven't just 'time 'd it so i don't have real numbers but the FEEL is better and ultimately that's whats important
also, shaved off about 4 seconds on boot, no a lot but every little bit counts |

At one point, glibc wouldn't build on a reiser4 partition (gcc bug), and for a long time gstreamer wouldn't work on reiser4. The difference is that you can open *any* file on a reiser4 fs as a directory, and that caused some programs to fail. |

Could you please explain how this works?

WTF?
And then? Can you put a file in that "directory"?

Code: | creideiki lfs # mkdir foo
creideiki lfs # cd foo
creideiki foo # touch bar
creideiki foo # cd bar
-bash: cd: bar: Permission denied
creideiki foo # ls bar/*
ls: bar/*: Permission denied
creideiki foo # chmod +x bar
creideiki foo # ls bar/*
ls: bar/*: No such file or directory
creideiki foo # cd bar
creideiki bar # ls
ls: reading directory .: Not a directory
creideiki bar # touch qux
touch: cannot touch `qux': Not a directory |
That's the way it works right now, on my system. Plugins might add a lot of excitement to that, though. _________________ <laurentius> gentoo linux?

Nice, but what the heck is the point in cding a file if you can't do anything with it? _________________ {Linux User #333296}

oh. the thread I just posted in got moved (https://forums.gentoo.org/viewtopic.php?t=214624)
I guess a cut+paste is easiest..
I patched gentoo-dev-sources (2.6.8-r1) and fixed the rejects myself (four of them).... it *appears* to be stable, but I'm only putting /usr/portage /usr/share/docs and /usr/src/linux on there for now (i.e. things that are easily replaced). It's an external USB2.0 drive coz my laptop HD ran out of space.
Looks like I'll be doing it again for -r3 (some fairly major fixes there..)
I might as well say that I'm running with bluez (bluetooth) patches now (although most of the bluez functionality is in vanilla now).
So my kernel is currently a
linux-2.6.8-gentoo-r1-mh1-reiser4
patched up the wazzu.
Had to resolve the reiser4 patch rejects myself though... |
