SOLVED The server failed to synchronize “[email protected]”’s mail because an error happened

[rardark]

Hi All,

I tried to transfer a cpanel account to a new server by transfer tool but I received a following warning:

The server failed to synchronize “[email protected]”’s mail because an error happened: (XID bd3hhg) “/usr/bin/dsync” reported error code “75” when it ended: Cpanel::Exception/(XID 75ajcy) Access Denied at /usr/local/cpanel/Cpanel/CpXferClient.pm line 273. Cpanel::CpXferClient::read_headers_from_socket(Cpanel::CpXferClient=HASH(0xf340d8)) called at /usr/local/cpanel/Cpanel/CLI/DsyncCpsrvdClient.pm line 64 Cpanel::CLI::DsyncCpsrvdClient::run(bin::dsync_cpsrvd_client_whm=HASH(0xa3cb20)) called at bin/dsync_cpsrvd_client_whm.pl line 55 doveadm([email protected])<31740><Yt1kCcEk1GH8ewAA+DqisA>: Error: read(remote) failed: EOF (version not received) doveadm(31740): Error: Remote command returned error 255: /usr/local/cpanel/bin/dsync_cpsrvd_client_whm xxx.xxx.xxx.xxx root 98DAQ8NNLP44XCV4PPB4J1IPKVIJB93S [email protected] server

However, I checked the mailbox of [email protected] and all the mail were successfully transfered. May I ask if this warning can be ignored or not?

Thank you very much!

If all the mails are there then it can be ignored. The error says that dovecot (IMAP server) returned an error while synchronising the mails:

Error: read(remote) failed: EOF (version not received) doveadm(31740): Error: Remote command returned

Are you transferring from an EOL server like CentOS 6 to a newer server?

Yea, both old and new server are running CentOS v7.9.2009.

By the way, may I know if I can "Pretransfer" the account to the new server so I can use the option "overwrite" to only update the modified files in order to speed up the migration process?

Thank you very much!

Overwrite will transfer everything again so unfortunately you can't pre-transfer easily from WHM but manually using rsync.

The transfer tool needs one hour to transfer the whole account but only needs 5mins to complete the overwrite process. It seems that "overwrite" uses rsync?

 

[andrew.n]

I was wrong, I apologise. You are absolutely correct. It does rsync the data what has changed and won't transfer everything over again. There was an old thread about this as well:

WHM Transfer Tool - overwrite option - does it rsync?

When using the "Overwrite" option in WHM Transfer Tool for an account that has the same username, does it rsync the data in the home directory, or does it perform a full deletion and rewrite from scratch?

Sorry for the wrong info

Never mind, thanks for your reply!

So I believe it is ok to pretransfer the account for speeding up the migration?

 

[andrew.n]

Yes it is certainly!

 

[rardark]

Yes it is certainly!

Thank you!
I'll do the migration later on.

 

[rardark]

Yes it is certainly!

I got so many duplicated mail after the overwrite process, strange...Do I have to remove all the emails in the new server before transferring?

 

[andrew.n]

@cPanelAnthony can you advise here why the "overwrite" option during the transfer might not sync the emails correctly?

 

[rardark]

May I ask if I can remove all emails by deleting all folders and files in /home/user/mail via ssh?

You can easily remove all email accounts from cPanel, that would be safer.

 

[rardark]

Migration success. Thank you very much!

 

[cPanelAnthony]

I'm so happy to hear you got the migration completed!
