[Ocfs2-devel] System hang issue when access the same dir/file from 2 different nodes at the same time
Hi All
I met a bug on kernel 2.4.24, rev 1303,bi-node system. Steps to
duplicate(a bug #111 has been reported to the bugzilla of
oss.oracle.com)
1.Write to a file(or create files in a dir) on one node for a
while(write to
the file 1000 times or create 1000 files in the dir)
2.Write to the same file ( or create files in the same dir) on another
node at
the same time.
Then, the system will hang with following error messages
...
(5461) ERROR at vote.c, 921: inode 67643, vote_status=0, vote_state=1,
lockid=34633216, flags = 0x8000, asked type = 5 master = 1, state = 0x0,
type = 5
Jul 27 16:31:06 westvile2 kernel: (2035) ERROR at vote.c, 921: inode
67661, vote_status=0, vote_state=1, lockid=34642432, flags = 0x40000004,
asked type = 5 master = 1, state = 0x0, type = 5
Jul 27 16:31:36 westvile2 kernel: (5461) ERROR at vote.c, 921: inode
67643, vote_status=0, vote_state=1, lockid=34633216, flags = 0x8000,
asked type = 5 master = 1, state = 0x0, type = 5
...
I have tried net vote and disk vote but get the same error message on
screen.
Any ideas on it ?
Thanx.

What revision of svn are you running? Would you mind trying the latest and seeing if it happens (some code to fix these cases has been committed) --Mark -- Mark Fasheh Software Developer, Oracle Corp mark.fasheh@oracle.com
