Resolved Error migrating tool

[SalvadorS]

Server operating system version

Debian 12

Plesk version and microupdate number

18.0.68

Hello,

I starting receiving this error when I try to use the migration tool:

Failed to fetch basic information about resellers, clients and domains data from source servers
Cause: Command execution failed on the local server with non-zero exit code.
command: rsync -r --chmod=Fu=r,Du=rwx,go= --timeout=30 -e 'ssh -i /usr/local/psa/var/modules/panel-migrator/sessions/20250329081054/ssh-keys/id_rsa.x.y.z.a -p xx -o PasswordAuthentication=no -o StrictHostKeyChecking=no -o GSSAPIAuthentication=no' /usr/local/psa/admin/plib/modules/panel-migrator/backend/lib/python/parallels/plesk/source/legacy/extras/plesk_17_0_pmm_shared/ [email protected]:/root/plesk_migrator/plesk_migrator-e6jimuvwpzgx5ysj5qnjjysy5x54rajq/pmm_agent
exit code: 30
stdout:
stderr: [sender] io timeout after 30 seconds -- exiting
rsync error: timeout in data send/receive (code 30) at io.c(201) [sender=3.2.7]

That is a critical error, migration was stopped.

The destination server is a new server and I never receive this error before....

I check it two different days always the same

Hello, @SalvadorS . Are you able to establish a successful SSH connection from the source server to the target server without the migrator, please? The error could result from a connectivity issue.

Hello @Sebahat.hadzhi and thanks a lot for your reply.

Yes, I can connect via SSH to the server. In fact the error is after I select the domains to transfer, so there is a initial connection....

 

[Sebahat.hadzhi]

Thank you for the confirmation. Could you please also try:

nmap source-server-IP -Pn -p22

traceroute -T source-server-IP

and confirm if you notice any connectivity issues? Also, could you please confirm what type of website you are attempting to migrate?

Hello,

Thanks again @Sebahat.hadzhi for your reply.

I can do that without any problem from the destination server:

Starting Nmap 7.93 ( Nmap: the Network Mapper - Free Security Scanner ) at 2025-03-31 13:00 CEST

Nmap scan report for servername (IP)

Host is up (0.00036s latency).

PORT STATE SERVICE

xxx/tcp open emsd-port

MAC Address: XXX

Nmap done: 1 IP address (1 host up) scanned in 0.11 seconds

traceroute to IP (IP), 30 hops max, 60 byte packets
1 servername (IP) 0.151 ms 0.152 ms 0.163 ms

Regarding type of website is a normal one, mail web... nothing special.

Is it possible that in the latest version of Plesk 18.0.68 there is some kind of problem with the migration tool? The Plesk firewall is enabled on both servers (allowing SSH access from the corresponding IPs), but even disabling it, the problem remains the same.

Thank you for the update and the provided details. This doesn't sound like an issue with the migrator to me. That error is observed due to poor network connection between the servers, which is something common. Although from the provided details doesn't seem like there's nothing obvious, at least with the first hop, that's not guarantee there isn't internment connectivity issue. If you have the option to get in touch with our support team, that will be my advise so they can connect to both servers and perform tests. If not, what I can recommend is to try creating a wrapper for rsync (at your own risk):

# mv /usr/bin/rsync /usr/bin/rsync_orig
# touch /usr/bin/rsync
# printf '#!/bin/bash\n/usr/bin/rsync_orig \"$@\"\nsleep 5\n' > /usr/bin/rsync
# chmod 0755 /usr/bin/rsync

Hello,

Thank you very much for your support. It seems there was a root process hung. Therefore, I restarted the server, and everything is working correctly again.
