Newest member and server move

[cirdok2]

Hi,
I am moving my forum from a VPS to a dedicated server and I am running some tests.
What I did a couple of times in the last days is:

- backup on the old server
- restore on the new server

Everything seems working fine but there is one thing I noticed: when I restore on the new server, the newest member shown on the home page is a test member I created after the previous restore. Seems only a visualization issue, because all the members are still there.

Probably an example will clarify what I mean:
- 25 October: backup and restore on the new machine; create a fake member test01 (number of total members 45000)
- 07 November: new backup and new restore; total members 50.000; in the forum statistics the number of users is correct, but the newest members is still test01 (that is not even in the DB since it was created only on the restore then dumped).

I am guessing this is because of the caching system (since I drop the DB before the new restore, that is the only place that info could be saved). What should I do then?

In the config I have

// ******** DATASTORE PREFIX ******
$config['Datastore']['prefix'] = 'forum1';
$config['Datastore']['class'] = 'vB_Datastore_Memcached';
$i = 0;
// First Server
$i++;
$config['Misc']['memcacheserver'][$i]           = '127.0.0.1';
$config['Misc']['memcacheport'][$i]               = 11211;
$config['Misc']['memcachepersistent'][$i]       = true;
$config['Misc']['memcacheweight'][$i]           = 1;
$config['Misc']['memcachetimeout'][$i]          = 1;
$config['Misc']['memcacheretry_interval'][$i] = 15; 

Should I erase the cache before the new restore? (if so, how? )
Should I change the prefix at each restore?
Could this issue carry other problems? Otherwise, I could leave like that, since if I create a new user, it appears correctly in the forum stats.

Thank you

On a related note, when I restore on a new server

Most users ever online was ...

is reset. Is this value not stored in the DB?

I am not sure how that can be cached. It looks like you have not shown that full section. Is it like this?

/*
$config['Datastore']['class'] = 'vB_Datastore_Memcached';
$i = 0;
// First Server
$i++;
$config['Misc']['memcacheserver'][$i] = '127.0.0.1';
$config['Misc']['memcacheport'][$i] = 11211;
$config['Misc']['memcachepersistent'][$i] = true;
$config['Misc']['memcacheweight'][$i] = 1;
$config['Misc']['memcachetimeout'][$i] = 1;
$config['Misc']['memcacheretry_interval'][$i] = 15;
*/

What about this section?

// ****** DATASTORE CACHE CONFIGURATION *****
// Here you can configure different methods for caching datastore items.
// vB_Datastore_Filecache - to use includes/datastore/datastore_cache.php

I omitted the first part since it is commented out.
Anyway, this is the full section:

//$config['Datastore']['class'] = 'vB_Datastore_Memcached';
//$config['Misc']['memcacheserver'] = '127.0.0.1';
//$config['Misc']['memcacheport'] = '11211';

        // ******** DATASTORE PREFIX ******
        // If you are using a PHP Caching system (APC, XCache, eAccelerator) with more
        // than one set of forums installed on your host, you *may* need to use a prefix
        // so that they do not try to use the same variable within the cache.
        // This works in a similar manner to the database table prefix.

$config['Datastore']['prefix'] = 'forum1';

        // It is also necessary to specify the hostname or IP address and the port the server is listening on

$config['Datastore']['class'] = 'vB_Datastore_Memcached';
$i = 0;
// First Server
$i++;
$config['Misc']['memcacheserver'][$i]           = '127.0.0.1';
$config['Misc']['memcacheport'][$i]                     = 11211;
$config['Misc']['memcachepersistent'][$i]       = true;
$config['Misc']['memcacheweight'][$i]           = 1;
$config['Misc']['memcachetimeout'][$i]          = 1;
$config['Misc']['memcacheretry_interval'][$i] = 15;

What happens if you comment out the memcache line and run your forums for a while?

What happens if you comment out the memcache line and run your forums for a while?

just tried: it shows the actual newest member and also the "most usual ever online" is correct!

But if I then uncomment the memcache lines, these two values are wrong again...
Should I flush the memcache before running the restore on the new server?
If so, is this the command?
echo "flush_all" | /bin/netcat -q 2 127.0.0.1 11211Thanks!
