This seems to be true (in Fedora, at least) for xfs as well, not just ext4.
I had been running the -fixes branch in Slackware 13.37 using xfs. All
worked fine and pretty quickly, too.
I had a problem (mentioned recently on this mailing list) with my remote
control in Slack so I switched to Fedora 15. I installed using xfs
since it is my fs of choice.
I was able to get things working but when I tried mythfilldatabase, the
drive light went on solid, my loadav went up pretty high and it just sat
I reformatted the partition into ext4, thinking that might fix the
problem, but no, it did the exact same thing, light on solid, etc. So,
I asked on here and was told to try ext3.
Just so everyone knows, yes...that fixed the problem. And thanks to
everyone who helped me.
One thing I *did* notice, is that it is slower than my previous
Slack13.37/xfs setup. I'm not sure if it is the more recent version of
MySQL with Fedora, or not...but, I did want to let people know that xfs
can be problematic as well.
