I've deleted those files with the native pvfs2-rm command which informed
me to run pvfs2-fsck. Running pvfs2-validate turned up a number more
which I removed. So there is nothing to pvfs2-viewdist on.
FWIW I'm running a meta on the head and the I/O servers on 16 compute
nodes, version 2.8.2

Ugh! Server 1, Received 64789 total handles instead of 64792
So the total handles have changed, as expected because of the removals,
but the difference is the same. Now to be honest, when I made that
filesystem, I didn't run an fsck so it could be a remnant from last
month. I don't know. But we have a bunch of Genomics people wrecking
havoc with those strange files in kernel space. I was able to do an
pvfs2-ls on them (user space) but didn't really pursue, hoping instead
to just make the problem go away!
Thanks,
Bill

Hi Bill,
Can you provide the output of pvfs2-stat on the parent directory
and affected files and 'pvfs2-viewdist -f <path>' on the affected files?
Do you see any complaints in the server logs related to accessing these
files?

Having some trouble with my filesystem. There are a few files which did

These cannot be removed. In the past, a run of pvfs2-fsck seemed to
correct these types of problems but this time all I get is the following
message and the fsck terminates. I'm not sure how to correct this.
Googling leads me to the source code. Anyone have any suggestions?
# pvfs2-fsck -p -v -m /scratch/pvfs2
# Current FSID is 1922795883.

Thanks, and Happy New Year to all!
