[Linux-cluster] RHEL5 CLVMD hang

[Finnur Örn Guðmundsson - TM Software]

Hi,

Althought i have not been in a similar situation, i would start by upgrading your nodes to the latest kernel & updates and see if you can re-produce the problem there. Otherwise your best bet would be contacting Redhat Support.

Thanks,
Finnur
