[gentoo-amd64] reiser4 desktop - worth it?
I have read that its quite useable now, is anyone running reiser4 ? Is it worth it in terms of performence and reliability? also, is it safe to run all partitions including / on reiser4. Im doing a fresh install (moving up to a raid system) how do I go about setting it up for reiser4? Thanks -- gentoo-amd64@gentoo.org mailing list

Although it will be quite sometime for any changes to make their way down to us users when they do is that going to mean a complete rebuild of our systems? If a function caller places its arguments in one set of registers and the callee uses different registers to receive the arguments in there is going to be problems. Well this issue can wait until the compiler gurus tell us how to deal with it. Well, I'll give a brief answer to this one: This isn't an issue. In the cases were registers are used to pass variables between function the ABI defines which registers should be used. Not that registers are always used. Basically the register allocator just decides which different temporaries or variables shall be stored in a register at a given point and which shall be spilled out to memory (though of course any value which is being currently used by a calculation must be in a register).

Reiser4 does not presently work with AMD64 architectures, so unless you want to lose your data, don't use it on an AMD64. If you want a vanilla kernel that supports Reiser4, you'll need to wait until version 2.6.13 is released. Or later, Andrew is just considering it and has asked Hans Reiser to remove the fs module loading stuff as he believes that it should be in the VFS layer and not the FS layer. I'm considering using Reiser4 for my own desktop machine, in addition to a pair of servers; I am, however, still fairly dubious about the author's grounding in sane filesystem design. While Reiser4 as it is seems to be usable, its future development plans (such as they are) concern me. I believe that Hans, the author of Reiserfs, has a firm understanding of FS design. I also believe that he is pushing it into areas that no one ever considered before and some of those might be dangerous to your data. Directories as files is definitely different from most of the other FS's but when he gets modules going it is going to be very cool and very scary. Cool when you can plugin whatever encryption module you want and scary because if there is a hiccup anywhere your data might never be recoverable. Beware of Ciaran. Yes, Ciaran loves to laugh at people that lose their data on that particular FS. ;-) If a file-system became corrupt and the world was going to end if it could not be recovered he would, in his best Nelson for the Simpsons voice, probably say, Ha, ha. Let the world end! I highly suggest backups for the adventurous. -- Tres -- gentoo-amd64@gentoo.org mailing list

That quite accurately sums up my concerns regarding the filesystem . :) Do you happen to know when the filesystem will be reworked to function correctly on AMD64 systems? I've been considering an upgrade to a pair of dual core Opterons, and I'd like to be able to use Reiser4 over Infiniband with a SAN array. -- Anthony Gorecki Ectro-Linux Foundation pgp9B6VN8guBM.pgp Description: PGP signature

How can you mirror filesystem data on a CPU? The motherboard (for the desktop machine) would likely be one of the Tyan dual Opteron configurations. I thought you meant dual servers.
