Backup and restore not working correctly

sfulham

Hey guys, so I’m trying to restore a backup, however, while the backup seems to go fine, when I attempt to login to an account in SOGo, it logs in, but shows no mailboxes or emails. If I attempt to resync, I get the following error:

Error: auth-master: userdb list: connect(/run/dovecot/auth-userdb) failed: No such file or directory Panic: file auth-master.c: line 436 (auth_master_unset_io): assertion failed: (conn->to == NULL) Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7fedbce2f872] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7fedbce2f98e] -> /usr/lib/dovecot/libdovecot.so.0(+0x1025eb) [0x7fedbce3c5eb] -> /usr/lib/dovecot/libdovecot.so.0(+0x102621) [0x7fedbce3c621] -> /usr/lib/dovecot/libdovecot.so.0(+0x55589) [0x7fedbcd8f589] -> /usr/lib/dovecot/libdovecot.so.0(+0x528b4) [0x7fedbcd8c8b4] -> /usr/lib/dovecot/libdovecot.so.0(auth_master_user_list_deinit+0x13f) [0x7fedbce264af] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_storage_service_all_next+0x4b) [0x7fedbcf7686b] -> /usr/bin/doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x734) [0x55ad27531fc4] -> /usr/bin/doveadm(doveadm_cmd_run_ver2+0x501) [0x55ad27542211] -> /usr/bin/doveadm(doveadm_cmd_try_run_ver2+0x3a) [0x55ad2754228a] -> /usr/bin/doveadm(main+0x1d4) [0x55ad27520e64] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xea) [0x7fedbc9ebd0a] -> /usr/bin/doveadm(_start+0x2a) [0x55ad275210ca]

Any ideas on how to fix this issue?

You did name everything (especially container and volume names) exactly the same as the backed up installation?

Yes

So I got everything back up and running. Turns out the issue was that the dovecot container wasn’t starting correctly because it couldn’t resolve domains. This was because I changed the subnet of mailcow due to conflicts, so I just had to add an access allow in the unbound configuration for that subnet, and it worked!
