[Lustre-discuss] More detail regarding soft lockup error

[Fourie Joubert]

  Hi

Many thanks for the reply!

The MDT is only 5% used.

OST's are all around 30%.

I have run the full series of e2fsck's.

Have been running 1.8.1 as it was built with weak dependencies to 
Infiniband, and I needed OFED 1.5 for my hardware....

But, I have recently been told by Marco Gomes (based on a recent forum 
discussion?) that 1.8.3 seems to work with OFED 1.5.2-rc2.

Will try to upgrade and see...

Thanks and kindest regards!

Fourie
