>Description:
sorry for bad english
I am using unionfs to create jail environment:
/usr /opt3/jail/ka6ah/usr unionfs ro,noatime
0 0
/bin /opt3/jail/ka6ah/bin unionfs ro,noatime
0 0
/lib /opt3/jail/ka6ah/lib unionfs ro,noatime
0 0
/libexec /opt3/jail/ka6ah/libexec unionfs
ro,noatime 0 0
/sbin /opt3/jail/ka6ah/sbin unionfs ro,noatime
0 0
When i start jail, jail processes deadlocks ("D" in ps), i cannot even
reboot after it.
Also after starting jail any process(non jailed) that trying to access
unionfs inside jail deadlocks too.
>How-To-Repeat:
try to make jail environment using nullfs, and start jail.
