Hello guys,

I'm sync'ing a DRBD unit, and I noticed that the amount of data to be
sync'ed differs on the /proc/drbd output. Is it a regular situation??

Here is the output from both:

==> node0:

version: 8.2.6 (api:88/proto:86-88)
GIT-hash: 3e69822d3bb4920a8c1bfdf7d647169eba7d2eb4 build by
buildsvn at c5-x8664-build, 2008-10-03 11:30:17
 0: cs:SyncSource st:Secondary/Secondary ds:UpToDate/Inconsistent C r---
    ns:11692032 nr:0 dw:0 dr:11692032 al:0 bm:799 lo:0 pe:12 ua:0 ap:0
oos:7023108792
        [>....................] sync'ed:  0.2% (6858504/*6869922*)M
        finish: 188:29:21 speed: 10,316 (10,172) K/sec

==> node1:

version: 8.2.6 (api:88/proto:86-88)
GIT-hash: 3e69822d3bb4920a8c1bfdf7d647169eba7d2eb4 build by
buildsvn at c5-x8664-build, 2008-10-03 11:30:17
 0: cs:SyncTarget ro:Secondary/Secondary ds:Inconsistent/UpToDate C r-----
    ns:0 nr:11695104 dw:11695104 dr:0 al:0 bm:745 lo:0 pe:0 ua:0 ap:0 ep:1
wo:b oos:7023484216
        [>....................] sync'ed:  0.2% (6858868/*6869920*)M
        finish: 183:40:06 speed: 10,620 (10,176) want: 10,240 K/sec

The node0 says 6,869,922, and the node1 says 6,869,920.

I have tried to sync this box a couple of times already, and it always gets
stalled at 100%.

I'm now upgrading from 8.2.6 to 8.3.12. Meanwhile, I was wondering if this
diff is acceptable.

Thanks,
Marcelo
