2 TB limit on a samba share
I'm running a server with Centos 3 that I have set up a smbfs share to a
Buffalo LinkStation. The LS has 4 drives configured with RAID 5. Each
disk has 1 TB capacity, so the resulting drive is approximately 2.7 TB.
When doing a df, the result shows 2 TB, and no used blocks. Is there
some setting I can change so that Centos sees and uses all 2.7 TB or
does Centos 3 not support this?

ethtool
We've just moved one a new server from our sever room, where I built it,
to the datacenter. We want to force autoneg off, and tell it gigabit and
full duplex. Using ethtool, I get no errors setting the speed or duplex.
HOWEVER, autoneg on works... and autoneg off utterly refuses to work, and
gives:
ethtool -s eth0 autoneg off
Cannot set new settings: Invalid argument

Disable autoneg on r8169?
Two problems I hope to solve:
1. The switch being used has autoneg off and has port set to 100 full duplex.
2. Many times NIC fails to come up properly during PXE boot:
r8169: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready
I can't use ethtool to disable autoneg because the nic driver is built
into a bzImage. The root fs is currently being mounted via nfs during
pxeboot at

OT: redhat training and RHES6
Greetings.
I am planning on getting my RHCE in the near future. I thinking I
should wait until 6 comes out before proceeding. That being said, I
don't want to wait past the end of this year.
That being said, do you all have any information about how long it takes
for their training platform to catch up to their release? Which is to
say, if RHES 6 is released on day 1, at what point

Could not setup Speed and Duplex on CentOS 5.5
Greetings,
I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that
the speed and duplex settings are 100 Half Duplex. I tried to change the
duplex settings to full, but no success. I got the error message "Cannot get
current device settings: Operation not supported". Does anyone else
experience this issue?. Below is the error message and some more details
about my box.

OT: backup media options
Greetings.
Sorry for the OT, but I'm looking for some advice regarding archiving.
I've always been a tape archive believer, but with SATA drives becoming
more reliable and much larger, I'm wondering if it is time to change my
opinion.
What are the benefits/pitfalls to begin archiving to "enterprise" level
SATA drives? Is it possible to use Amanda or Bacula to archive

Network issue - Windows works but CentOS does not
I am having an extremely strange issue with a BL460c1 (G1) blade on a
c7000 enclosure. I could not for the life of me get the machine to ping
the gateway or any other blade on the same enclosure (yes, the subnet
mask was correct & quadruple-checked); although pinging to the local IP
works. I was almost convinced that it was a network or hardware issue;

3Ware 9550SX-4LP Performance
I know there are a few 3Ware fans here and I was hoping to find some help. I
just built a new server using a 3Ware 9550SX-4LP with four disks in raid 5.
The array is fully initialized but I'm not getting the write performance I was
hoping for -- only 40 to 45MB/Sec.
3Ware's site advertises 300MB/Sec writes using 8 disks on the PCI Express
version of this card (the 9580 I think.)

Lockup using stock r8169 on 4.8 in gigabit mode during heavy transfer on lan
I have no output in the logs, but /etc/init.d/network restart fixes the issue.
I am rsync/scp (10GB) data from one 100MB Full duplex host to an ASUS M3A78-EM
(RTL8111B/C). It locks up around the 1.5GB Tx mark.
If I ethtool -s eth0 autoneg off speed 100 duplex full it does not happen again.
Ideas?

changing partition priority on install
Greetings.
I am in the process of installing 5.1 64 bit on a server. The server
has 2 3ware cards: 9550SX 12 port, and a 8006 2 port, both SATA.
I want the 8006 board to be /dev/sda, and the 9550 to be /dev/sdb. My
plan is to install the os on /dev/sda (8006), and data on /dev/sdb
(9550). Unfortunately, the 9550 comes up as /dev/sda.
The 8006 is installed in slot 3, which is a 100Mhz

[Hardware] Good Server I/O on-the-cheap: ASL Monarch 811x with CentOS 4.2 ...
Since good server designs have come up in the past, I wanted to point
out a "low-cost" server option that has good I/O, and the vendor offers
_your_choice_ of not only Fedora Core or Red Hat Enterprise Linux, but
_also_ CentOS _shipped_ with it!
IN-A-NUTSHELL ...
Starting at just over $750, you can get a single Socket-939 Opteron 1xx

3Ware 9550SX and latency/system responsiveness
Dear list,
I thought I'd just share my experiences with this 3Ware card, and see
if anyone might have any suggestions.

nfsmount default timeo=7 causes timeouts on 100 Mbps
I can't explain why 700 msecs aren't enough to avoid timeouts in 100
Mbps networks, but my tests verify it, so I'm writing to the list to
request that you increase the default timeo to at least 30, or to 600
which is the default for `mount -t nfs`.
How to reproduce:
1) Cabling:
server <=> 100 Mbps switch <=> client
Alternatively, one can use a 1000 Mbps switch and

Routing issue?
Hi,
At first glance, this appears to be a fairly simple routing issue,
but I''ve checked the configuration and am a bit mystified. I am using
Xen 3.0.2 here in bridged networking mode.
Firstly - four servers.
Dom0 - 75.126.2.202 (RHEL4)
domU (CentOS) - 75.126.3.248 -> 75.126.3.251
Dom0, .248, & .249 can all talk to each other okay (& the outside world)
However, for some

network collapse
based on what your saying.. im not thinking this is samba related.
I guess check your switches and find the "fault" autosense for your nics..
You can use thisone to disable autosence
ethtool -s ethX autoneg off
en set correct nic speed.
ethtool -s ethX speed XXXX
BUT ! check your switches first.

nfsmount default timeo=7 causes timeouts on 100 Mbps
I think I got it.
Both nfsmount and `mount -t nfs` now default to rsize/wsize = 1 MB.
By lowering this to 32K, all issues are gone, even with the default
timeo=7. And nfsroot=xxx client responsiveness is a whole lot better.
I think when nfsmount was initially written, the default rsize/wsize
were much lower, which matched the timeo=7.
Now they cause the lags/timeouts that I reported.
So

Win2K box and the file server are on the same switch. They are both
configured as 100FD, AutoNeg=Off. I have not met anyone so far with that
much performance difference, though some reported 1:2 speed ratio. Attached
is our config file for your information.
I've searched through this mail lists' archives. I couldn't find a solution,

2.6.9-42.ELsmp kernel and 3ware 9550 tools
I have the latest kernel with the drivers for my 3ware 9550SX built in.
Where
can I find the tools and monitoring apps for this card? Are there rpms
hiding
somewhere, or do I need to build it from source?
