Category: Filesystem Group: None >Status: Closed Resolution: Out of Date Priority: 4 Submitted By: David Zafman (dzafman) Assigned to: John Byrne (jlbyrne) Summary: nodedown/kswapd deadlock Initial Comment: I ran the following commands one node 1 (CLMS master) # while(true) > do > cp -f /boot/vmlinuz-2.4.20dzafman-sandbox /tmp > done Then I took nodes 2,3,4 down. although it is possible that only a single nodedown would reproduce this. Nodedown deadlocked with kswapd. The process running "cp" command is also waiting for kswapd.
