Hello! I can't understand how to verify process works. In my mind, it calculate differents between this node (where verify was running) and another replicas. I have three-nodes resource (every with local storage) csshv-90 - Primary csshv-91 - Secondary csshv-94 - Secondary
root@csshv-90:~# drbdadm verify one-vm-106-disk-0 root@csshv-90:~# dmesg -T|grep 106-disk-0|grep 'Online verify found' [Tue Apr 28 18:59:53 2020] drbd one-vm-106-disk-0/0 drbd1034 csshv-91: Online verify found 8 4k blocks out of sync! That's all. Primary get me, that there is only 32kb out of sync on csshv-91 No any error messages on another nodes. Then we go to csshv-91 root@csshv-91:~# drbdadm verify one-vm-106-disk-0 root@csshv-91:~# dmesg -T|grep 106-disk-0|grep 'Online verify found' Nothing found - no problems but in the same time root@csshv-90:~# dmesg -T|grep 106-disk-0|grep 'Online verify found' [Tue Apr 28 19:12:57 2020] drbd one-vm-106-disk-0/0 drbd1034 csshv-91: Online verify found 8 4k blocks out of sync! root@csshv-94:~# dmesg -T|grep 106-disk-0|grep 'Online verify found' [Tue Apr 28 19:13:02 2020] drbd one-vm-106-disk-0/0 drbd1034 csshv-91: Online verify found 97632 4k blocks out of sync! Hm... how many out-of-sync... Why? And, finally go to csshv-94 root@csshv-94:~# drbdadm verify one-vm-106-disk-0 root@csshv-94:~# dmesg -T|grep 106-disk-0|grep 'Online verify found' [Tue Apr 28 19:43:43 2020] drbd one-vm-106-disk-0/0 drbd1034 csshv-91: Online verify found 97632 4k blocks out of sync! No any error messages on another nodes. WTF? 382MB out-of-sync??? Between csshv-94 and csshv-91? But no out-of-sync between csshv-94 and csshv-90(primary)? And only 8 out-of-sync blocks betweeh csshv-91 and csshv-90(primary)? I can't understand this process. Can anybody make clear it for me?
