Even with so called stable 2.6.18 release there are same problems.
When a process get stuck in D state inside VE (probably trying to access files on nfs mounts), there are usually corresponding one of the [events/cpunum] kernel thread in D state, meaning the only way
is to hard reset the node (or little better use MagicSysRq for cleaner reset).
One of the things i've noticed that makes these hangup D processes
to appear much less frequently, is that you should run portmap on HN too (since i've noticed there are HN dmesg notifications smthing like portmap not responding, i don't know if it's regaring portmap not reponding inside VE of the HN itself, since there is one kernel
and one dmesg, and i can't if a specific dmessage is related to some VE or the HN itself). Another thing i did ,out of paranoia, is just install nfs-utils on HN too. I'd love to hear from the developers what they think about this portmap issue?
In general the nfs support in OpenVZ is very BAD, i've bugged the
developers several time about a year ago, but nothing changed since. Since i've got the feeling that nfs support is not important feature for them i've not bugged them since then.
