Re: [SLE] differences between reiserfs and ext2?
[Clinton Rogers]
stupid gnubie question for today: what are the differences between reiserfs and ext2? are there any throughput/speed enhancements for using reiserfs?
Hello. I'm using ReiserFS since one or two days, and I have the strange feeling it is a bit faster on reads. `bonnie' has a different opinion: using default options (I'm lazy, but maybe not very serious), `bonnie' says: -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU ext2 100 714 87.2 4420 48.5 1938 49.1 1214 90.6 4728 73.2 80.7 10.0 reiserfs 100 985 66.2 4266 39.1 1158 25.1 862 65.0 4818 66.9 92.5 11.2 Also, especially during the ReiserFS test, the machine was not quiescent. The main user difference I see is that ReiserFS recovers quite safely, and also much faster, from a power failure. Also, since that file system does not use i-nodes, you do not have i-node limits (yet in practice, for one, I did not meet any i-node limit in years). Note that you cannot boot a kernel image from a ReiserFS partition. Instead, people set up a small ext2 `/boot' partition (a few Megs at most) for this. -- François Pinard http://www.iro.umontreal.ca/~pinard -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

You can. Just mount the partition that contains the kernel with the -notail option. Ciao, Stefan -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
