[Lustre-discuss] lustre can not mounted problem

[Klaus Steden]

Hi there,

I suppose I should ask all the obvious questions, like:

* does your IB card have an IP address assigned to it?
* does it have the right netmask configured for the address?
* do the other machines on the IB network also have addresses on them with
the correct netmasks?
* have you tested TCP/IP on any other hosts in your cluster and confirmed
that it is working as expected?

I don¹t have a lot of experience with broken IB cards, but they¹re just as
subject to IP misconfiguration as Ethernet can be ... I don¹t recall offhand
if there are hardware layer diagnostics for the (I¹m assuming Voltaire) card
itself, but there probably are, and they could help you verify physical
connectivity. However, assuming your IP configuration is both valid and
usable, if it¹s still inoperable, then you probably have a bad card. Have
you tried the other IB port (if the card has more than one), or swapping
another IB card from another host that you know to be working?
