Dear All,

Lustre version: 2.4.3

OS: RHEL/SL 6.5

Just wondering if anybody has seen something similar: I have some applications that fail with an error “No space left on device”, for example a copy command has failed while copying a 500MB file while we have over 500TB space left.

And this is intermittent, I have been able to copy files larger than that after those failures. I have seen this erorr with applications like CHARMM and Gaussian.

Only a handful of 3% of our OST’s have reached 100% usage, but this should not cause it as I understand.

Any thoughts on what could be causing this and how can I go about debugging this will be a great help.

Thank you,
Amit
