Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Nevermind, I used the generic drbd.conf from the HOWTO and unfortunately
the default net settings were too slow. A few omre settings to the
drbd.conf may be a good addition to the HOWTO.

Subject: [DRBD-user] DRBD Long Sync Wait


I am new to drbd and just set up a drbd device of about 55GB in size. It
is mounted by heartbeat (datadisk) as /home. It is to act as a mirrored
filesystem over my two-node cluster.

Here is the drbd.conf file:

resource drbd0 {
  protocol = C
  fsckcmd  = /bin/true

  on bilbo1 {
    device  = /dev/nb0
    disk    = /dev/cciss/c0d0p3
    address =
    port    = 7788

  on bilbo2 {
    device  = /dev/nb0
    disk    = /dev/cciss/c0d0p3
    address =
    port    = 7788

I ran a test and piped a good 1MB of text into a file on the /home
partition, and the entire sync process had to start over. The sync
process looks like it will take over 60 hours.

Is there any configuration change I can make to speed this up? I gather
a failover would be a bad thing during syncing, but its hard to expect a
failure to wait 60 so the syncing can finish.
