[SOLVED] Slow operation when migrating a container

[ninelynx]

Hi all. I'm trying to do a project for school with high availability and we choose do it with proxmox, but I have a little problem.
I have 3 nodes, and the storage the de VMs and containers is on NFS connected directly with the nodes of proxmox.

My problem is, when I try to migrate doing restart method on container, it takes several minutes to power on with all the services configured there,
By the way, I can do ping to the machine.

Someone knows the problem?

Special thanks!

Hello and welcome on PVE

Maybe not enough power? Please give us some more information:

1. pveversion -v
2. what os runs in the container and what applications
3. Gigabitconnection is working fine on all hosts?
4. What HW exactly you have deployed? What CPU, HDD's/SSD's, what Raidlevel
5. Raidcontroller, ZFS?
6. What OS is the NFSserver, and what hardware is there deployed?

Please do also an pveperf on you storages. For example:
For you lokal machines if you have only the system use only that command "pveperf"
For NFSshare use it with path "pveperf /mnt/pve/yournfsshare"
If you have your NFSserver also installed with pve it is easy to do this command directly on you NFS-Server.

2.- The container is running with Kodi Media Server and Debian 9.

3.-Yes, Gigabit connection is working fine with all servers.

4.-
Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz (1 Socket)
16GB RAM
I don't have SSD in the machine.
Also a HDD of 500GB, and no RAID.

5.-Any raidcontroller or zfs.

6.-

The OS in NFS is debian 9 the latest version. Also im not sure about the HW because it is a machine that the school give to me for do the project.

Thanks a lot!

SOLVED.
I try to reduce de size of the HDD in the containers and it work.

I have 8GB on the containers, before they have 30GB.
