Are you utilising SSDs? Is the kernel log (dmesg) clean from errors on the backing devices (also mdraid members/backing devices)? Did you verify the mdraid array consistency and are the array's members in sync? -------- Ursprüngliche Nachricht -------- Von: d tbsky <tbskyd at gmail.com> Gesendet: 18.

I try to play with config options and resync about 15 times, still can not get verify report 0 oos. I have about 10 resource which has verify problem. but it's strange that some resources are ok. the largest resource is about 1T and it is ok. the resource I am testing now is only 32G. the host structure is: two sata disk (mdadm raid 1) -> lvm -> drbd the host has ecc ram so the memory is ok. the most confusing part is the resync data is very small, it is only a few kilo bytes and sync done in 1 seconds. I don't know why it can not be synced correctly. I also try to run command "md5sum /dev/drbdX" at both node to check. they are indeed different.
