Hi all;
When I access the data hosted in that share using others mount ways
(except the smbmount/mount.cifs/mount -t smbfs/mount -t cifs) all works
fine, downhere a benchmark:
1) Transfer a 500 mb file:
netcat - 27 seconds
ftp - 31 seconds
smbclient - 38 seconds
mounted (cifs) - 2:58 minutes
I'm having a big problem with delay mounting a share using smbmount or
mount -t cifs.
First idea, wonder that could be the kernel (2.4.33.3), I was having a
locking issue too so I upgraded to 2.6.19.2 for use CIFS (later, in
other compilation, went to 2.6.19.3), same problem.
I already tried all "smb.conf tweaks" - like read raw, socket options
and all that kind, nothing solved this problem. Already compiled the
both kernels (server and client) with SMB/CIFS options and nothing seens
to solve my problem. Here is my last smb.conf (just the basic - note:
the smb.conf tweak don't change nothing in this case):
[global]
workgroup = TEST
netbios name = TEST
valid users = @users
admin users = @users
[data]
comment = data
path = /data
read only = No
There are around 150 terminals which should access that share (that runs
a Cobol's 35 Gb database), half users are Windows and for those, the
access is just perfect, the others users should access from Linux using
smbmount (or another way that I don't know) and they run directly to
that longe delay scenario.
Thought that could be a DNS issue, so created a DNS (and Winbind) zone
with everything OK, created /etc/hosts entrances for each Linux box (and
at each client for the server) for eliminate this possibility, so,
nothing change.
The CIFS logs at clients are alright (and in fact, if I map using smbfs
instead CIFS, the efect runs just the same).
The commando used for mounting is:
mount.cifs //10.1.15.105/data /data -o username=user,password=test
Note: the options recordio, noperms, nobrl and the whole meal were just
tested.
Checking...
samba version (from 3.0.23c to 3.0.23d)
smb.conf
kernel version (from 2.4.33.3 to 2.6.19.3)
name resolution
cifs for better performance
I'm just running out of possibilities, googling that I found some
related problem (but without solution) to gigabits NICs - and my whole
DMZ is 1000 mbps.
Can someone please give me a light? I'm just running out of options.
Thanks.
