Hi,
this applies for drbd 0.7.17.
I was trying to get drbd to work only using drbdsetup (not drbdadm) without
configuration files.
As I wrote in
http://lists.linbit.com/pipermail/drbd-user/2006-April/004856.html I'm
experiencing very slow syncing.
Now I found that maybe the default syncing rate in drbd/drbd_main.c line
1339 is given in B/s and not in KB/s as it should be.
I guess instead of
mdev->sync_conf.rate = 250;
there should be
mdev->sync_conf.rate = 250*1024;
I don't understand the shaping algorithm up to now but changing that seems
to work somehow. Now I see in /proc/drbd:
version: 0.7.17 (api:77/proto:74)
SVN Revision: 2093 build by XXX, 2006-04-24 19:09:50
0: cs:SyncTarget st:Secondary/Primary ld:Inconsistent
ns:0 nr:37104 dw:37104 dr:0 al:0 bm:10 lo:15 pe:6384 ua:15 ap:0
[======>.............] sync'ed: 32.3% (86076/123120)K
finish: 0:01:29 speed: 924 (820) K/sec
instead of:
finish: 0:15:21 speed: 4 (4) K/sec
This is for sure better - since faster - but somehow not really shaped at
250 K/sec. I don't mind that since I don't really need shaping.
Warm regards,
Martin
