Description

Hi,

Playing around a bit with vkernels I found that fsx failed quite early on them
in a UFS filesystem, so I wanted to try on a real machine, which produced the
same result.

Check http://leaf.dragonflybsd.org/~tuxillo/archive/temp/test.fsx.dat.fsxlog

I've passed fsx also on my HAMMER filesystem without issues (around 5 minutes also).

Is there any known issue with UFS that makes fsx to fail?

Cheers,
Antonio Huete

Hi,

I've just run fsx on a 2.4.1 VM with UFS filesystem for about 1.30h without a
single failure. See the log here:

There is fragility betwen the VM system and the filesystem. I've
slowly been consolidating the VM getpages/putpages code and some
of the new read-ahead code in vm_fault broke UFS's getpages.

I just pushed fixes. Try it now.

Antonio,
Did you try to reproduce the problem after the fixes were pushed?

Hi,

This can be closed. It survived a 18h test.

testcalls = 23412481
