Therefore it's most probably related to the WD drives. WD desktop drives are well known for being (voluntarily) crippled for RAID operation. They will almost always create all sort of weird problems when running under high IO load. It is of utmost importance that you at least take care of setting TLER in the correct mode on the drives. Beware that apparently newer WD drives don't even allow setting TLER properly anymore (I said "crippled"). http://en.wikipedia.org/wiki/Time-Limited_Error_Recovery -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | <eflorac@xxxxxxxxxxxxxx> | +33 1 78 94 84 02 ------------------------------------------------------------------------ _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
