Hi: it is not ssd. it is just two 2TB sata hard disks. mdadm is checked every week and I don't see any error report under dmesg. there are 20 VMs running above it and they seems normal. but I wonder it will be normal again after so many verify/resync. so I just pick a test-vm to try. still trying the config options to see if I can get it resync. I can also use dd to resync it but then the problem may disappear and I won't know what happened. any suggestions to find out what happened? 2016-05-19 4:50 GMT+08:00 Veit Wahlich <cru.lists at zodia.de>: > 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.
