[Ocfs2-users] ocfs2 file system hang during copy files

[Zosen Wang]

I am trying to copy a single 42 gb file from et3 file system to ocfs2 file system on node 1. The ocfs2 file system hang
on all nodes after/during the cp. The /p0ebsdb/u13 is an ocfs2 mount point shared with other 2 nodes (3 nodes rac). 

 

The following is unix copy command

[root at b30svrxp-ebsdb1 migrate]# time cp aexp02.dmp /p0ebsdb/u13/junk

 

real    17m49.351s

user    0m0.392s

sys     1m49.065s

 

The following is dmesg on node1

 

ocfs2_dlm: Nodes in domain ("A2AECED66891407D915CBF282A9E9299"): 0 1 2
