Hi Felix, yes all volumes didn't sync even when the /etc/init.d/drbd status said - Primary/Secondary UpToDate/UpToDate C I just finished to manually copy all devices onto the xen002. And about the " meta-disk /dev/vgmain/lv_drbd-meta[0];" you said you are not familiar with it, have a look here - http://www.drbd.org/users-guide-8.3/ch-internals.html#s-meta-data-size my disk size total is 2 TB that means with drbd formula: Mmb<(Cmb/32768) + 1 Mmb<(1024*1024*2/32768) + 1 Mmb<65 and here - http://www.drbd.org/users-guide/re-drbdconf.html#idp10760864 meta-disk internal, meta-disk device, meta-disk device [index] When an index is specified, each index number refers to a fixed slot of meta-data of 128 MB, which allows a maximum data size of 4 GB. This way, multiple DBRD devices can share the same meta-data device. For example, if /dev/sde6[0] and /dev/sde6[1] are used, /dev/sde6 must be at least 256 MB big. Because of the hard size limit, use of meta-disk indexes is discouraged. My meta lv device is 10GB big (lvcreate -L 10GB -n lv_drbd-meta vgmain), i think big enough for 2TB of max disk usage.
