Disk Space used by filesystems?
So. Everything in Linux is a file right? After redoing my laptops FS from EXT4 to JFS, this was because I read somewhere that JFS was very fast, I find that my HD is only using about 600MB vs the 950+MB that it did wih EXT4 after a fresh install. I've Google-ed and looked around and can't find out file-system comparisons by well....the space the file system using on the drive. Any info would be great. Thanks

Re: Disk Space used by filesystems?
Ext4 and JFS/XFS are more or less on par with each other in my experience. I dunno what to tell you about the 600 MB vs. 950 MB thing...

Re: Disk Space used by filesystems?
Don't know about Ext4, likely it's the same. EXT3 has "reserved blocks" in order to avoid system problems when the FS gets full.
To disable them, you might want 'tune2fs -m 0 -r 0 <device>', but then be careful to never get the root FS full.

Re: Disk Space used by filesystems?
Renan is right... I forgot about that. You probably don't wanna disable them though.
