I have a user that reported a problem creating a file on our Lustre filesystem.
When I investigated I found that the problem appears to be unique to just one
filename in one directory. I have tried numerous ways of creating the file
including echo, touch, and "lfs setstripe" all return "No space
Can you paste us the file name? I want to see if we can touch
something like this.

The filename is not very unique. I can create a file with the same name in
another directory or on another Lustre filesystem. It is just this exact path
on this filesystem. The full path is:
/lustre/scratch/smoqbel/Cenval/CLM/Met.Forcing/18X11/NLDAS.APCP.007100.pfb.00164
The mount point for this
Hello Robert,
could you please send a mail into our ticket system? Kit or I would then start
to investigate tomorrow.
Thanks,
Bernd

Andreas,
Here are the results of my debugging. This problem does show up on multiple
(presumably all) clients. I followed your instructions, changing lustre to lnet
in step 2, and got debug output on both machines, but the -28 text only showed
up on the client.

Hello Mike,
you really should fill a ticket to us (DDN). I think your problem is from
these MDS messages:
LDISKFS-fs warning (device dm-1): ldiskfs_dx_add_entry: Directory index full!
LDISKFS-fs warning (device dm-1): ldiskfs_dx_add_entry: Directory index full!
And /dev/dm-1 is also the scrat
Hmm, seems there is no solution available except of to turn off dir-indexing.
I never looked into the dir-index code so far, but wouldn't it make sense to
skip the index just for this directory?

Andreas,
I never saw this message either. It is showing up in the output of dmesg, but
is not written to any log files that I can find. I miscounted the number of
files in my original message. The actual number is a little more than 11
million files. I am in the process of working with the user
