[Ocfs2-devel] System hang issue when access the same dir/file from 2 different nodes at the same time

[Chen, Yukun]

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

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

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.
