Hi all,

I have drbd 8.3.0 compiled onto SLES 10 SP. It synchronises according to
/proc/drbd.
(version: 8.3.0 (api:88/proto:86-89) - GIT-hash:
9ba8b93e24d842f0dd3fb1f9b90e8348ddb95829 build by root at SS3, 2009-02-19
14:33:19)

I am curious as to the meaning of the abbreviations "cs:, ro:, ds:, C,
r---" and "ns:, nr:, dw:, dr:, al:, bm:, lo:, pe:, ua:, ap:, ep:, wo:
oos:" on Primary:
0: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r---
ns:0 nr:1647046760 dw:1647046740 dr:0 al:0 bm:89398 lo:5 pe:0 ua:5 ap:0
ep:1 wo:b oos:0

and on Secondary:
0: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r---
ns:1647533344 nr:0 dw:1027130144 dr:1519887000 al:436112 bm:448475 lo:0
pe:1 ua:0 ap:1 ep:1 wo:b oos:0

I have seen a question about it some many months ago in this list I
believe, but can not find it any more. "man drbd" does not explain it,
and on the website I can not find anything.

Could someone direct me to the info please.

TIA

:-)
Al
