Diskless means just what it sounds like. The disk is not available. Probably its been grabbed by the LV manager. A primary/diskless node will simply do I/O on the peer, but I dont believe that will work unless the peer is also primary which is not your situation.
I dont think you are looking at what you believe you are looking at. hth Dan From: [email protected] [mailto:[email protected]] On Behalf Of Edwige Odedele Sent: Thursday, July 21, 2011 7:28 AM To: 'Felix Frank'; 'drbd-user' Subject: Re: [DRBD-user] cs: Unconfigured Hi, I just want you to know that it is working beside the issue of this commands: > root@sd-xxxx5:~# cat /proc/drbd > version: 8.3.7 (api:88/proto:86-91) > GIT-hash: ea9e28dbff98e331a62bcbcc63a6135808fe2917 build by root@sd-xxxx5, > 2011- > 05-04 10:47:00 > 0: cs:Connected ro:Secondary/Secondary ds:Diskless/UpToDate C r---- I made the node primary and also test: lvscan, pvscan, vgscan and all issues was right. I also checked the disk contains. But I wonder to know why I still have ds:Diskless. Did somebody ever faced this problem?

I'm especially unsure whether the empty lvs output means that LVM is not the culprit. You may want to check vgscan, pvs and their ilk. Do find out what has claimed your backing device. That's the single most important step right now. HTH, Felix
