Some information for creating ext3 filesystem

small_boy22 · 02-01-2006, 10:19 AM

hi,
I want to use ext3 for a disk that I have which is mainly for storage of movies, mp3 and stuff..
So I have some questions:

1)What should I use with the -T option: 4K(news) or 1MB(largefile) ?
-> The disk capacity is 200GB.

2)What type of journal should I use ?
full journal, metadata-only etc.. ?

This hard disk is gonna be strictly for storage and not a fileserver or anything else..
I will use 2.6 kernel.

Full journaling makes writes quite a bit slower (takes about twice as long as all data is written twice). I would avoid this.

I would also use the largefile setting, as the files are generally going to be quite large.

I'm guessing you want a fault tolerant filesystem for all that "Legitimate" music and movies you have acquired. The only way you can truly be fault tolerant is with RAID or backups. I do backups of my 70GBs of "legitimate" stuff.

Also, I personally use ReiserFS with NOTAIL mount options and a large blocksize for best speed. Ext3 is slow compared to a properly tuned reiserfs.
Another option for a filesystem would be XFS or JFS. I hear they are really good with large files, but XFS requires more CPU power than JFS.
