<DIV name="wrteplaceholder"><PRE dir=ltr>Today I changed the time of my primary node from 05:44 to the correct 06:44
<BR>UTC, which should be nearly the same as on the secondary. I did this by a
<BR>reboot of the primary only and changed the time in BIOS.
<BR>
<BR>Here the part of syslog on the secondary:
<BR>Mar 22 06:45:57 via2 kernel: drbd0: Connection lost.
<BR>Mar 22 06:47:53 via2 kernel: drbd0: Connection established. size=2980 KB /
<BR>blksi
<BR>ze=4096 B
<BR>Mar 22 06:47:53 via2 kernel: drbd0: Synchronisation started blks=64
<BR>
<BR>Now it seems to sync forever:
<BR>root@via2:~# date
<BR>Mo Mär 22 10:27:32 UTC 2004
<BR>root@via2:~# cat /proc/drbd
<BR>version: 0.6.10 (api:64/proto:62)
<BR>
<BR>0: cs:SyncingQuick st:Primary/Secondary ns:0 nr:0 dw:0 dr:0 pe:0 ua:0
<BR>
<BR>This seems to be very long for 3 GB and a 100 Mbit direct link.
<BR>Did I hit a curious testcase?
<BR>
<BR>This is my (untuned) drbd.conf:
<BR>resource drbd0 {
<BR> protocol = C
<BR> fsckcmd = fsck -p -y
<BR>
<BR> disk {
<BR> do-panic
<BR> disk-size = 2980k
<BR> }
<BR> net {
<BR> sndbuf-size = 512k
<BR> sync-nice = -18
<BR> }
<BR> on via1 {
<BR> device = /dev/nb0
<BR> disk = /dev/hdc1
<BR> address = 10.0.10.10
<BR> port = 7788
<BR> }
<BR>
<BR> on via2 {
<BR> device = /dev/nb0
<BR> disk = /dev/hdc1
<BR> address = 10.0.10.11
<BR> port = 7788
<BR> }
