[Orange-tech] xseed: errors in opening files on some nodes

[Toni Alatalo]

hi again Mark,

started getting strange behaviour with files, but only on some nodes:

now for this certain file e.g. node 42 works:
xseed1:~ orange$ /opt/pdsh/bin/pdsh -w 10.224.10.42 
ls /nfs/xseed2/homes/orange/elephant/production/02_scissor_attack/02_04.blend 
10.224.10.42: /nfs/xseed2/homes/orange/elephant/production/02_scissor_attack/02_04.blend

but e.g. node 44 does not:
xseed1:~ orange$ /opt/pdsh/bin/pdsh -w 10.224.10.44 
ls /nfs/xseed2/homes/orange/elephant/production/02_scissor_attack/02_04.blend 
10.224.10.44: 
ls: /nfs/xseed2/homes/orange/elephant/production/02_scissor_attack/02_04.blend: 
Input/output error

.. opening the file (with Blender) fails on the nodes where that ls command 
fails too. so based on the info about which nodes succesfully started 
rendering, these nodes work now for that file, but not others:

10.224.10.42
10.224.10.49
10.224.10.50
10.224.10.55
10.224.10.56
10.224.10.57
10.224.10.59

should pdsh and the fileshare work reliably, or am i using a wrong approach 
for the distributed rendering? .. without pdsh working we would not be able 
to start drqueue slaves either, so i guess it has to be trustworthy..
