[Lustre-discuss] ldlm_cli_cancel_req()) Got rc -108 from cancel RPC: canceling anyway

[Miguel Angel Gila Arrondo]

Hi all,

We're seeing the same error message in our Lustre clients when umounting a 
lustre filesystem, but only in a very specific situation:

When trying to empty an OST with the simple data migration script 
(http://manual.lustre.org/manual/LustreManual18_HTML/LustreOperatingTips.html#50532487_pgfId-1292867), 
sometimes inconsistences appear. Doing ls -lh in the client that just ran the 
script shows 0 file size for some files, while doing it in another client shows 
the correct file size for the same files. 

This gets solved by umounting and mounting again the Lustre filesystem, 
although the mentioned error messages appear in /var/log/messages of the 
client:

Is anybody else seeing these messages in this situation? Does anyboyd know for 
a workaround??

Cheers,
Miguel
