	DRBD setup problem by Szasz Tamas-2 Mar 26, 2008; 03:15am :: Rate this Message: - Use ratings to moderate (?) Reply | Reply to Author | Print | View Threaded | Show Only this Message Hi list, I installed drbd-8.2.5 from source on a running system. I have moved all from the /var partition to a created /var directory. I want to use this free partition(/var) to drbd. When I want to start the drbd, I get this error: # drbdadm create-md data v08 Magic number not found md_offset 67225174016 al_offset 67225141248 bm_offset 67223089152 Found ext3 filesystem which uses 66589392 kB current configuration leaves usable 65647548 kB Device size would be truncated, which would corrupt data and result in 'access beyond end of device' errors. You need to either    * use external meta data (recommended)    * shrink that filesystem first    * zero out the device (destroy the filesystem) Operation refused. Command 'drbdmeta /dev/drbd0 v08 /dev/sda5 internal create-md' terminated with exit code 40 drbdadm aborting Here is my config file: global {         minor-count 1; } resource data { protocol C; #incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; halt -f"; startup {     wfc-timeout        0; ## Infinite!     degr-wfc-timeout   0; ## 1 minutes. } handlers{    local-io-error "echo 0> /proc/sysrq-trigger; halt -f";    #split-brain "echo split-brain. drbdadm -- --discard-my-data connect $DRBD_RESOURCE ? | mail -s 'DRBD Alert' root"; } disk {     on-io-error pass_on; } net {     # timeout           60;     # connect-int       10;     # ping-int          10;     max-buffers         2048;     ko-count            4;     after-sb-0pri       discard-older-primary;     after-sb-1pri       call-pri-lost-after-sb;     after-sb-2pri       call-pri-lost-after-sb;     # max-epoch-size 2048; } syncer {     rate   10M;     #group   1;     al-extents 257; } on YBKX007453 {     device      /dev/drbd0;     disk        /dev/sda5;    address     192.168.10.13:7789 ;     meta-disk   internal; } on YBKX007451 {     device     /dev/drbd0;     disk       /dev/sda5;     address    192.168.10.12:7789 ; } } Where is my misstake?
