Hi folks, drbd in Primary/Secondary mode, using drbd 8.4.10 on Debian 10:
I had a problem with a RAID controller; all disks became unavailable. Drbd took over giving the node access to the disks on the other node via network. Amazing. I took down the containers running on the affec- ted host, made the other host primary and started the containers on the "good" node. Now the RAID controller has been replaced, but after running a verify /proc/drbd shows me that the hosts are not in sync: # cat /proc/drbd version: 8.4.10 (api:1/proto:86-101) srcversion: 473968AD625BA317874A57E 1: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r----- ns:0 nr:92520660 dw:92520660 dr:663924532 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:732 2: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r----- ns:0 nr:5103000 dw:5103000 dr:663924532 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:1036 How comes that the secondary doesn't pick up the data from the primary automagically? Using policy C it is obvious the the unaffected host got all the data.
