[Lustre-discuss] rc -43: Identifier removed

[Per Lundqvist]

I got this error today when testing a newly set up 1.6 filesystem:

   n50 1% cd /mnt/test
   n50 2% ls
   ls: reading directory .: Identifier removed
   
   n50 3% ls -alrt
   total 8
   ?---------  ? ?    ?       ?            ? dir1
   ?---------  ? ?    ?       ?            ? dir2
   drwxr-xr-x  4 root root 4096 Feb  8 15:46 ../
   drwxr-xr-x  4 root root 4096 Feb 11 15:11 ./

   n50 4% stat .
     File: `.'
     Size: 4096            Blocks: 8          IO Block: 4096   directory
   Device: b438c888h/-1271347064d  Inode: 27616681    Links: 2
   Access: (0755/drwxr-xr-x)  Uid: ( 1120/   faxen)   Gid: (  500/     nsc)
   Access: 2008-02-11 16:11:48.336621154 +0100

   Change: 2008-02-11 15:11:31.352841294 +0100
   
this seems to be happen almost all the time when I am running as a 
specific user on this system. Note that the stat call always works... I 
haven't yet been able to reproduce this problem when running as my own 
user.

dmesg from client:

   ...

where error 43 means: Identifier removed. 

No error messages from the MDS or OSS:s.

setup:
