Test#2

Today the updated configuration to the nodes of my HA Storage. Created a virtual machine and started to install ubuntu on it. During installation, I rebooted the active node. As a result, the PM node has received:

root@cl02-n01:~# pvscan
  /dev/NASLUN0VG0/vm-100-disk-1: read failed after 0 of 4096 at 34359672832: Input/output error

  Total: 2 [4.29 TiB] / in use: 2 [4.29 TiB] / in no VG: 0 [0   ]


And VM is hungup.

So, after rebooted node returned to online, I rebooted the second one. At PM node has received:

root@cl02-n01:~# pvscan
Found duplicate PV 4hKm0l1uebbcn5s3eV3ZUT6nb6exKjOD: using /dev/sdc not /dev/sdb
PV /dev/sdc VG NASLUN0VG0 lvm2 [4.00 TiB / 3.97 TiB free]

Total: 2 [4.29 TiB] / in use: 2 [4.29 TiB] / in no VG: 0 [0 ]


Seems to be /dev/NASLUN0VG0/vm-100-disk-1 is available now, but VM is in hungup stage anyway. At PM GUI about my VM:

Status: running
CPU usage: 50% of 2CPUs (im use 2 CPU at config)


PS.
At active Storage node dmesg show:
