I Would like to understand well the following message which appears to 
me during a resync:
local disk flush failed with status -95

errno.h seems to say:
#define EOPNOTSUPP      95      /* Operation not supported on transport 
endpoint */

After some research, I have understood that this is in relation with 
"I/O barriers".

If I've got this message, there is something (OS, driver, disk, ...) in 
my system which does not support "I/O barriers", does it ?

So, if "I/O barriers" are not supported, are my data protected ???
