Poll: A Slacker's choice for a FS...

trashbird1240 · 06-20-2008, 08:13 AM

I should be a little more detailed:

Code:

/home/joel> mount
/dev/sda1 on / type jfs (rw)
...
/dev/sda3 on /home type jfs (rw)
...
/dev/sdb5 on /media/multimedia type ext3 (rw,acl)
...
/dev/joelusb on /home/joel/usb type vfat (rw,noexec,nosuid,nodev)

I used jfs for / and /home this time because someone (I forget who) recommended it as faster than reiserfs. The big drawback I see, that I failed to notice before I installed 12.1, was jfs does not support ACL, whereas reiserfs and ext3 do. I think my multimedia disk has been ext3 since I got it, and I just didn't change it for lack of space to move the data. I think I'll keep it that way, since the ACL makes it easy to share the data between users on this home desktop.

All my removable drives are vfat, but I may change my main thumbdrive to a Linux filesystem, as I'm even carrying it around less. The digital camera should stay vfat, because I might use it to tranfer photos to a[n unenlightened] family member's machine. They may not respect their own software freedom, but they still love pictures of the kids

I've been using ext2/3 because that's what Slackware setup for me when I started with Slackware 9.1. Been using it since because I've never had to reinstall Slackware.

Maybe it was me, but I can tell you that JFS DOES SUPPORT ACL, see:

I believe that's what you're talking about, right ? POSIX ACL, right ? The above was taken from the 'Linux Kernel v2.6.21.5 Configuration' using 'make menuconfig'.

I'm pretty sure jfs has ACL support as well.

Code:

/usr/src/linux-2.6.24.5/fs/jfs/acl.c

A quick google search for "jfs ACL linux" comes up with some information.

Personally, I'm pretty excited about the upcoming ext4.

slackass · 06-20-2008, 11:48 AM

I've been using ext3 just because thats what Slack defaults to during the install and I didn't know any better. I'm going to do a install on JFS to try it out.
I use a separate boot partition for grub with ext3. Would JFS be suitable for that also?

JFS does support ACL. This is from jfs.sourceforge.net:

Quote:

09/06/02
JFS patches for extended attributes and ACLs are available for release 1.0.21 (see JFS patches)

So, JFS has supported ACL for a while now.

digger95 · 06-20-2008, 01:32 PM

I've been experimenting with xfs for about a week. Then yesterday I reinstalled everything and put jfs on just because I'm in a playful mood and have some free time to experiment. Didn't do any benchmarks so it's entirely subjective, but on my machine ext3 seems to be the best fit. Feels a bit zippier than the other two, and in the past it has always recovered well from power outages. I'm sure the others might have as well, but for now I think I'll stay with ext3. Always fun playing around though.

trashbird1240 · 06-20-2008, 08:40 PM

Gosh, how embarrassing...

Well, I stand corrected, thanks for setting me straight about ACL on jfs.

In case you're wondering where I got the idea that jfs does not support POSIX ACL: the mount(8) page does not mention the acl option for jfs, as it does for ext2,3 and reiserfs. So, when I set up my new fstab after installing Slack 12.1, the option was not recognized -- I forget specifically what problem I had, but I remember not being surprised when I read the mount(8) page. It's not a big deal now, everything's working fine.

Sorry for the misinformation: I've corrected the page on Slackwiki.

The installation times slowed considerably. I tested installing with ext3 and reiserfs. They seem about the same now.
XFS installs about the same as well.

I believe installation is the best test of a filesystem

I used to split the partition into: / : 16384M, swap : 1024M, and /home : whatever is left. I thought this was a good idea.

Then I thought, "Who cares." No I don't bother using swap. I have a Gigabyte of ram. I use the entire partition.

Reiser is stable, so I don't know why Patrick V. decided to default to ext3 now. All this talk of corruption and I've never once lost a filesystem under Reiser, nor have I in ext3.

But I totally understand the feeling you get when you understand something totally such as a tried and tested filesystem like ext3. I keep trying to tell my employer's that upgrading to the latest visual studio is a bad idea. But I think all of the filesystems are important. Lot's of choice is great.

Now if Slackware would support laptops better.

Your choice of course

. Suggestion: "man tune2fs"

. Lets you make an ext3 out of ext2 without loss of data or re-formatting. If needed you can even re-convert back to ext2. I use the "journal=data" option in "/etc/fstab" with no noticeable less fast writing btw. There is also a nearly ready ext4 if you are in the mood to try.

Since some are concerned with compatibility, I'll give a link to UFS Explorer : http://www.ufsexplorer.com/
It's a windows shareware but it may save your life. :P

And XFS here.

JFS for /
JFS on my TrueCrypt drive for /media/storage

Maybe one day I'll remount my home directory as a TrueCrypt drive on session start.

JFS FTW, no matter what the vote indicates. :P

Just curious calraith, Is there an advantage to using TrueCrypt over the builtin Luks/mdcrypt stuff?

You know truecrypt has some rather cool features, one of the most interesting being:
