Unwanted JFS and XFS processes

Hi there, I'm not sure this thread belongs here but... here goes.

I found that was my system was not responsive to my tastes - considering that Arch is pretty minimal, that wasn't good. I did a ps ax and here's what I found :

151 ?        S      0:00 [jfsIO]
  152 ?        S      0:00 [jfsCommit]
  153 ?        S      0:00 [jfsCommit]
  154 ?        S      0:00 [jfsSync]
  155 ?        S<     0:00 [xfslogd/0]
  156 ?        S<     0:00 [xfslogd/1]
  157 ?        S<     0:00 [xfsdatad/0]
  158 ?        S<     0:00 [xfsdatad/1]
  159 ?        S      0:00 [xfsbufd]

Processes concerning JFS and XFS, one might think, heh. The problem is that I'm not using these two filesystems at all and I don't want useless processes running on my machine, obviously.

Now, I know that filesystem support is built into the kernel so, would I need to recompile my current kernel to remove support for both or are those processes started somewhere else ? I've looked at /etc/rc.conf but to no avail.

Thanks.

Re: Unwanted JFS and XFS processes

Got them here too:

root       138  0.0  0.0      0     0 ?        S    19:35   0:00 [jfsIO]
root       139  0.0  0.0      0     0 ?        S    19:35   0:00 [jfsCommit]
root       140  0.0  0.0      0     0 ?        S    19:35   0:00 [jfsSync]
root       141  0.0  0.0      0     0 ?        S<   19:35   0:00 [xfslogd/0]
root       142  0.0  0.0      0     0 ?        S<   19:35   0:00 [xfsdatad/0]
root       143  0.0  0.0      0     0 ?        S    19:35   0:00 [xfsbufd]

... And my system is like greased lightning.

(What filesystem are you using? If it's ext3, the reason for low performance might be that you're not using dir_index.)

Re: Unwanted JFS and XFS processes

To remove these process, you'll need to recompile your kernel without xfs and jfs. However, these process don't affect your performance as they don't use any CPU or RAM.

Re: Unwanted JFS and XFS processes

Well if they don't eat resources, I won't be recompiling my kernel just to clean up my process list. Thanks.

Gullible Jones : I'm using ReiserFS as filesystem except for my /boot partition which is ext2.
