JFS On Arch Linux

Hey all! I know that XFS isn't a good choice if I want one huge partition since Pacman hates it. But what about JFS? Does JFS work well with Pacman?

Hmm. This is kind of an ambiguous statement.
Pacman doesn't hate XFS. Rather, XFS is typically slower than other filesystems when dealing with many small files.  YMMV.
Pacman's cache is stored under /var. /var contains many small files.

FWIW, I use JFS for everything and pacman is fine; quite zippy.
Try using the deadline i/o scheduler with JFS, and see the JFS wiki page for more.

Re: JFS On Arch Linux

I'm also using JFS for everything on both my workstation and lappy. I find it much faster than ext3 and less prone to lag in large directories. Use it -- it works!

Re: JFS On Arch Linux

I just use ext3 for everything - it doesn't seem any slow than JFS, and directory indexing makes it as fast as ReiserFS with large numbers of small files.

Re: JFS On Arch Linux

Ever since I was shown JFS, I just used it. All my partitions (except those used by other OSes such as Syllable which require eg AFS) use JFS.

As I'm getting a new PC, I've been considering different filesystems and for Windows compatibility I may need to use FAT32 or ext2 (and the Win32 IFS driver) for my data partition(s), but in terms of Linux, if the kernel is built with support for JFS, I'll use JFS.

I see you've referenced XFS a bit. Does Linux have XFS now?!

Windows was made for looking at success from a distance through a wall of oversimplicity. Linux removes the wall, so you can just walk up to success and make it your own.

Re: JFS On Arch Linux

I use JFS for everything except /boot these days... I'm not 100% sure about it's 'stability' in terms of power outages etc as I'm experienced some issues with external hard drives that loose power without being unmounted, and the laptop battery dying before shutdown. The normal boot-up checks didn't fix it and I had to run a manual fsck to get the devices to mount again.

Yes, for quite a while now

...ported to Linux, with the first distribution support appearing in 2001/2002

I would love to see some data/tests (that I could duplicate) that show ext3 performs as fast as reiserfs when dealing with a large number of small files. It would immediately convert me to ext3 forever!
