Good Morning, One of the OSTs in a lustre file system I manage is showing a higher usage. I attempted to stop writes by setting the max_create_count to zero and then moving data off it but that doesn't seem to be working.
> lfs df | grep OST:15lustre19-OST000f_UUID 71145018368 62653382656 8491631616 > 89% /lustre19[OST:15] MDS> lctl set_param osp.lustre19-OST000f*.max_create_count=0 MDS> lctl get_param osp.lustre19-OST000f*.max_create_count losp.lustre19-OST000f-osc-MDT0000.max_create_count=0 lfs find /lustre19/expphy/volatile --ost lustre19-OST000f -size +50M | lfs_migrate -y I've been watching it, and the ost in question isn't shrinking. I can see its size usage go down a bit... and then tick up a bit w/r, Kurt J. Strosahl System Administrator: Lustre, HPC Scientific Computing Group, Thomas Jefferson National Accelerator Facility
