Network Time Synchronisation failed

[Vasilij Lebedinskij]

Hello! I've encountered a trouble after hardware update on my server. I have a SAS controller in IT mode and 4 drives with ZFS raid 10 root on it. After I've added two ssd pic-ex drives for cache and log my SAS drives disappeared from bios boot menu - I think its some bios issue but I have no time to dig this out. So I've installed clean Proxmox on USB flash drive, imported rpool and extracted lxc configs to new Proxmox installation. All containers started fine. But if I reboot my host I can't boot again. Boot process hangs on job Network Time Synchronisation - it fails and run again in loop. I can detach sas controller with my pool and PVE boots from flash fine. If I disable time synchronisation service I can't use lxc because I get fuse filesystem error on startup afterwards. What am I doing wrong?

PVE 6.4 (I tried to update but nothing changes)

This service probably relies on NTP (Network Time Protocol) which uses UDP port 123. Deactivating this service is a rather bad idea, because many applications require the participants to have the (nearly) exact same time.

Is this port blocked by a firewall or something similar?

No it not! I've tested ntp and checked its log everything is syncing successfully. I wonder shy does this job fails only when zfs pool is mounted?
