[SuSE Linux] Disk Fragmentation
My most recent forced fsck revealed that the partition mounted as /opt contains 13.5on-contiguous files. That sounds high to me, at least from a DOS FAT perspective. My /opt has had a lot of items removed (Applix) and added (kernel source via link to /usr/src), so I'm not too surprised. Do I need to take any action with non-contiguous files at a 13.5% level? If so, now what? I don't think I've seen any "defrag" apps for Linux. Does one tgz, rm and untar? Opinions of wiser heads needed.

.... I haven't had any issues with it myself, but I know Wolfgang had posted something a couple of times about disk fragmentation on linux, if I can find it I'll forward it to you private mail.... maybe it'll be of some use to you. He basically said that fragmentation on Linux isn't such a big deal, and that you don't need to 'defrag' as you would with the other os Michael On Wed, 2 Sep 1998, Howard Arons wrote:

Aeh, I merely translated. The original (in German) is by Kristian Koehntopp.

wrong perspective. :-) Well, I'll forward you the text, if anyone else wants it, please mail me. If many want it, I'll put it on the list. The short answer is: The ext2 filesystem does use clever routines so that fragmentation only appears in non-dangerous ways even with concurrently writing processes and 95 0.000000illed disks. The internal readahead and cache algorithms see to it that any existing fragmentation is not hurting the total throughput. -Wolfgang -- PGP 2 welcome: Mail me, subject "send PGP-key".

I _knew_ that DOS perspective would eventually distort my vision :-) Your answer is quite reassuring (and the detailed filesys info is informative as well). I'm not going to worry about it any more; I'm in good hands with Linux.
