[DRBD-user] Setting up a new configuration without lose files..

[Ítalo Rossi]

Hello,

I have a linux server with two disks (1.7T) using LVM2 (xfs  
filesystem) and I want to use drbd to replicate this device to  
another server.

How can I activate this configuration without lose any files on  
production server?

My server is redhat el4 and drbd Version: 0.7.24 (api:79).

This is my scenario:

Disk /dev/sda: 1796.7 GB, 1796776919040 bytes
255 heads, 63 sectors/track, 218445 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb: 1796.7 GB, 1796776919040 bytes
255 heads, 63 sectors/track, 218445 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda and /dev/sdb with LVM2 and xfs filesystem:

/dev/mapper/stg--emails-md3000--0    3509190656 2436322340  
1072868316  70% /my_mountpoint


the res0 is in production without any problems...

resource res0 {
	...
}

resource res1 {
        protocol C;
        disk {
                on-io-error detach;
                size 3509321728;    # <-- Is this correct??
        }
        syncer {
                rate    100M;
        }
        on host1 {
                device  /dev/drbd1;
                disk    /dev/stg-emails/md3000-0;
                address xxx.xxx.xxx.xxx:7789
                meta-disk       internal;       # <-- Is this  
recommended?
        }
        on host2 {
                device  /dev/drbd1;
                disk    /dev/sdb1;
                address xxx.xxx.xxx.xxx:7789
                meta-disk       internal;
        }
}

I'll need to format de /dev/drbd1 ?

Thanks in advance!
