[Ocfs2-users] MMAP shared in OCFS2 filesystem

[Eckenfels. Bernd]

Shared mmap is not supported, we had some discussions on that, but it is
just not there yet. This also affects bdb files.

Hi,

My homedir is inside an ocfs2. When i use mysql client it should create
a .mysql_history file with the commands i've inputted so far.

The file is created but no data is recorded inside. If i do a simlink
outside ocfs everything is ok..

I've narrowed it down to the following code:

...
open("/home/rv/.mysql_history", O_RDWR|O_CREAT|O_TRUNC, 0600) = 3
ftruncate(3, 13)                        = 0
mmap(NULL, 13, PROT_READ|PROT_WRITE, MAP_SHARED, 3, 0) = -1 EINVAL
(Invalid
argument)
close(3)                                = 0
write(1, "Bye\n", 4Bye
)                    = 4
exit_group(0)                           = ?
Process 10776 detached

I'm using 2.6.9-48.ELxenU with ocfs2-tools-1.2.4-1 and
ocfs2-2.6.9-48.ELxen-1.2.5-0.local.

Any info on this?
Thanks
Nuno Fernandes
