Probably so. > As for STONITH use, I think you should always use power reset, like the > stonith script external/ipmi, power reset can do a quick and "real" reset > to the server hardware and not depend on OS behavior, that's what we need > for stonith to do. Yes, I'd agree. My only worry was that, at least during a testing phase, the hardware may get more than its fair share of tear and wear. AFAIK, hard reset is the equivalent of pulling the power cord. > Recently I build a 4-node HA cluster for my cite's LVS with pingd and > stonith supported.

Under which circumstances was that happening? Is that a problem with ipmitool or with the stonith script itself? Thanks, Dejan > > Regards, > > Chun TIAN (binghe) > > ?? 2008-1-23??????11:40??
