- I will try to have a look into the jobstats and see what I can find, but I
made sure the files I moved were not in use when I moved them.

Is there possibly something else I am missing? Also, does anyone know a good
way to see if some client is writing to that OST and determine who it is if
it's more probable that that is what is going on?

How safe do you think this would be to run on some files on the OST with it
disabled on the MDS and active jobs running on the cluster? I could do this by
group, possibly to mitigate concerns of open files, if need be.

As I have gone through the testing, I think you may be right. I think I
disabled the OST in a slightly different way and that caused issues.
Do you happen to know where I could find out a bit more about what the "lctl
set_param osp..max_create_count=0” command would do?

# 4 and #2 are the only expected behavior. I'm not sure what the behavior
should be in the case of #1 and #3.

3. Deactivating the OST shows it as inactive in the MDS but UP in the Client.
(not expected.)
4. I am able to delete a file that spans that OST with the OST deactivated, no
hang.
I think the only thing here that concerns me a bit is #2.

Hi Rick,
I thought what I had done was disable it on the MDS, but perhaps I was
following the wrong instructions. Do you know where the best instructions for
what you are describing can be found? I would be willing to try again.

Does anyone know of a good quota reporting tool that can give quota information
in the same way as a 'repquota -u' or 'repquota -g' would?

Oh and as for the MDS/OSS setup, here's a brief overview too:
2x MDS in failover mode with one MDT
12x OSS in fail over pairs with 12 OST per pair 6 running on each OSS. (72 OST,
6 active on each of 12 OSS for load sharing.)
Each OSS pair is hooked to the same set of 2x RAID Arra

Any thoughts anyone?
