Hello to everyone,
 
I have a lustre file system (servers and cliente with lustre 2.3). The filesystem work fine, but the files of a specific directory I can’t access to the files.
 
For example this files has the next atributes from a client:
 
[root@login-hpc-02 ~]# lfs osts
OBDS::

But if I try to access or delete I only get:
 
ls: cannot access hubble_psf_660__691_555_.psf: Interrupted system call
 
or if I try to delete:
 
rm: cannot access hubble_psf_660__691_555_.psf: Interrupted system call
 
 
Any suggestions to access or delete the files?
 
 
Thanks in advance

Does it fail right away, or after some waiting?
Anything interesting you see in dmesg after that?
If not, perhaps try to capture a lustre log of the operation at some extended log level and see if there are any clues there?

Bye,
Oleg
