[DRBD-user] changing clock time and sync

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

I encountered a similar problem, I believe.  Sometimes, while the two hosts are in full sync., there is a glitch in the connection, and consequently they restart the full sync from the beginning.

Is there anything that could be done to avoid this.  I have started by increasing the timeout value in drbd.conf.  I still haven't checked if it helps.
Anything else that can be done?

[DRBD-user] changing clock time and sync

Today I changed the time of my primary node from 05:44 to the correct 06:44
UTC, which should be nearly the same as on the secondary. I did this by a
reboot of the primary only and changed the time in BIOS.

Here the part of syslog on the secondary:
Mar 22 06:45:57 via2 kernel: drbd0: Connection lost.
Mar 22 06:47:53 via2 kernel: drbd0: Connection established. size=2980 KB /
ze=4096 B
Mar 22 06:47:53 via2 kernel: drbd0: Synchronisation started blks=64

Now it seems to sync forever:
root at via2:~# date
Mo Mär 22 10:27:32 UTC 2004
root at via2:~# cat /proc/drbd
version: 0.6.10 (api:64/proto:62)

0: cs:SyncingQuick st:Primary/Secondary ns:0 nr:0 dw:0 dr:0 pe:0 ua:0

This seems to be very long for 3 GB and a 100 Mbit direct link. 
Did I hit a curious testcase?

This is my (untuned) drbd.conf:
resource drbd0 {
  protocol = C
  fsckcmd  = fsck -p -y

  disk {
    disk-size = 2980k
  net {
     sndbuf-size = 512k
     sync-nice  = -18
  on via1 {
    device  = /dev/nb0
    disk    = /dev/hdc1
    address =
    port    = 7788

  on via2 {
    device  = /dev/nb0
    disk    = /dev/hdc1
    address =
    port    = 7788
