Hello list! I use DRBD 0.6.12 (with heartbeat 1.21). Sometimes I get some real high load on my machine (load average around 6) and a zombie process like drbd_syncer_2 or drbd_syncer_3. I believe the zombie process causes the high load. Also i lost a drbd connection without reason (one connection of four). Additional information: the zombie processes disappear after some time and the load is normal again. Zombies exist only on the drbd "PRIMARY" machine (all drbd devices in primary mode). My questions: 1. Could it be a zombie process who killed the drbd connection? 2. Why these Zombies live on my machine? Here some output: # top --- snip --- 3339 root 9 0 0 0 0 SW 0.0 0.0 0:00 drbd_asender_3 3340 root -1 -20 0 0 0 Z < 0.0 0.0 0:00 drbd_syncer_3 <defunct> --- snap --- --- snip --- node1:/# cat /proc/drbd version: 0.6.12 (api:64/proto:62) 0: cs:Connected st:Primary/Secondary ns:576 nr:0 dw:576 dr:425 pe:2 ua:0 1: cs:Connected st:Primary/Secondary ns:3596 nr:0 dw:3596 dr:1393 pe:5 ua:0 2: cs:Connected st:Primary/Secondary ns:36 nr:0 dw:36 dr:385 pe:0 ua:0 3: cs:Connected st:Primary/Secondary ns:98566160 nr:0 dw:16 dr:98566297 pe:0 ua:0 node1:/usr/src# node2:/# cat /proc/drbd version: 0.6.12 (api:64/proto:62) 0: cs:Connected st:Secondary/Primary ns:0 nr:568 dw:568 dr:0 pe:0 ua:0 1: cs:Connected st:Secondary/Primary ns:0 nr:3576 dw:3576 dr:0 pe:0 ua:0 2: cs:Connected st:Secondary/Primary ns:0 nr:36 dw:36 dr:0 pe:0 ua:0 3: cs:Connected st:Secondary/Primary ns:0 nr:98566160 dw:98566160 dr:0 pe:0 ua:0 --- snap --- THANKS for any help! -- Best regards, Andreas Semt
