Hi there ! I need some more explanations in order to know from where comes a barrier problem (message local disk flush failed with status -95). I have identified the following different levels of the chain that may be involved: - OS: I am currently running on Red Hat Enterprise Linux ES release 4 (Nahant Update 6) kernel 2.6.9-67.ELsmp. Is there a minimum required kernel version for the barriers implementation ? - DRBD: The current version I am using is drbd-8.2.5. - Drivers: I currently use disks connected on a HP Smart Array 642 Controller using the cciss driver 2.6.16 provided by the Red Hat Enterprise Linux ES release 4 (Nahant Update 6). I haven't seen any option on this driver. - Controller: I will check in there is any cache option in the HP Smart Array 642 Controller firmware. - Disks: I will try to find any information on the disks used in order to check if the used some cache. Anything else I have forgotten ? Thank in advance, Best regards. -- Hervé GAUTIER
