Amazingly old mail thread. Anyway, would you try strace and find which systemcall returns the error? And if you can, try re-compiling aufs module with CONFIG_AUFS_DEBUG=y, set the module parameter 'debug' to Y, and reproduce the problem. Then we may be able to see something in the kernel log if we have a luck. J. R. Okajima ------------------------------------------------------------------------------
