Please note that drbd creates virtual disk devices above the actual disk partition. For example, you can have /dev/nb0 above /dev/hda2 and /dev/nb1 above /dev/hda3 and so on. Your file systems are created on the virtual device and any data on the disk you access normally is through the virtual device. This way, drbd gets to intervene in these operations and synchronize the secondary node with writes you make to these partitions. Here's an example how to setup a new drbd partition (assuming your configuration file, drbd.conf is ok): mkdir -p /var/lib/drbd" /etc/rc.d/init.d/drbd start drbdsetup /dev/nb0 primary (this makes sure you can access /dev/nb0) mkfs -b 4096 /dev/nb0 tune2fs -j -c0 -i0 /dev/nb0 echo "/dev/nb0 /mnt/disk ext3 noauto,data=journal 0 0" >> /etc/fstab (Udate fstab accordingly) mkdir -p /mnt/disk /etc/ha.d/resource.d/datadisk drbd0 start <aleks.n at telus.net> [DRBD-user] drbd.conf Hi , I am struggling to understand how drbd works ..... In drbd.conf , what is the relationship between device=/dev/nbd/0 and disk=/dev/hda2 ( my root partition ) ? I loaded the module ..... insmod nbd .... then /dev/nbd/0 shows up in my filesystem .... I run /etc/init.d/drbd start which does not show any output ( should there be ? ) ... Then I try mkfs -t ext3 /dev/nbd/0 ..... which fails ( I forget the exact error messages , I'll repost if that's important ) . in /etc/fstab I put ..... /dev/nbd/0 / ext3 ........ etc. Does this make sense ? I get on boot ......... EXT3-fs : unable to read superblock mount : wrong fs type , bad option , bad superblock on /dev/nbd/0 or too many mounted file systems . _______________________________________________ drbd-user mailing list drbd-user at lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user ----------------------------------------------------------------------- Walla!
