Hi all,

The recent post regarding replicated server mounts has caused me a bit of 
work.

Basically, I broke the functionality a bit when I merged the patch I 
received from Michael Blandford.

I believe the included patch fixes this.

Additionally, while fixing it I stumbled on the "BUG: dir already mounted" 
message that has been annoying us for so long.

I think I've fixed that as well. It's only about my third attempt at it 
so I'm not expecting it's final. Maybe third time lucky.

Anyway, since the change is a bit more than straight forward I'd like 
as many people as can to test it out before I commit and release it in 
4.1.3. I've probably broken something else.

The patch:

I've posted RPMS with this patch applied on my people page:
     http://people.redhat.com/~jmoyer/

Version 4.1.2-4 is what you want.  I'll make the page a bit more
user-friendly when I get some free time.  Packages for RHEL 3, Fedora Core
1, and Fedora core 2 are available.  I also have the source rpms posted.

Happy testing,

Jeff

Re: Please help - cleanup

[raven]

Hi all again,

Further to yesterdays replicated server patch I have done some cleanup to 
it.

This patch replaces the previous patch so you will need to back out the 
previous one before applying this one.

I have:

- corrected some inconsistent messages.
- cleaned up paths (there were some double slashes,
  function was OK though)

One problem remains and seems not to be easily fixed. For multi mount 
maps dead mount point directories (from failed mounts) are left. This is 
not simple to fix without breaking other functionality. I believe it is 
better than those "BUG" messages though. So we`ll have to live with it for 
now.

If anyone is able to test this also that would be great.

Thanks
Ian

Hmm... along the same lines, I just configured ghosting for a map which
uses wildcards (which I'm guessing is not supported, right?). If you cd
to a directory, any directory, it will create that directory and leave it
around, even though there is no such mount.  This sounds like something
that should be fixed up.

I will roll another test rpm with this patch and post to my people page.

That problem is a little different to the one sited above.

If there is a map that contains some entries and a wildcard map at the end 
I can't tell if the directory should be removed or not. So either we keep 
that behaviour or we disable ghosting altogether when a wildcard map 
entry is seen.

In the past I considered that if ghosting was requested in this case I 
would leave the entries and allow autofs to "learn" about the mounts as 
it went.

So what do people think we should do here?

Has anyone had the chance to test this?  autofs-4.1.2-5 from my people
page, or the patch Ian sent to the list?  I'd like to hear feedback, either
positive or negative as I have to push a package into FC2 before the
freeze on Friday.

I have not had a chance to play with it extensively.  I will dedicate 
time to it tomorrow.

Just a couple of questions

1) What about the get-best-mount.patch?  My impression was it wasn't 
needed with the new replicated server patch. 

2) What kernel modules are you going to add to the kernel?  Is it the 
20040417 ( for 2.6 ) or are you going to wait for the newest ones from Ian?

3) Are you going to add your yp patch to your rpm?

I've cut patches last night that sync up 2.4 with 2.6.

If I'm not sure about the current fix status I'll forward the relavent 
stuff to Jeff and Axel otherwise I'll put together a release. Looks like 
there are a few too many recent changes to autofs to rush into a release.

I'm not certain of this, as I haven't had a chance to test w/o it.  As I
mentioned before, I ran across a problem with clients that got their maps
from LDAP.  They would timeout given the low timeout value passed to
rpc_ping.  If we just tell it to use a long timeout value, this seems to
work.  As I mentioned, this is a band-aid, and I haven't debugged the real
problem.  I'm hoping Ian's patches fix it.

Unfortunately, the kernel is frozen.  I will have to wait until the pool
opens up again before I can get any changes in.  In general, we don't take
patches that aren't upstream, so it's important that the changes make it
into the Linus tree.

mlblandf> 3) Are you going to add your yp patch to your rpm?

That will be present in the version I build into FC2.  It is not present in
4.1.2-5.

I have a system running it right now and it's behaving as expected, but 
I haven't done any in depth testing of it because of other priorities. 
What would be nice is to have a suite of smoke tests that I could run 
through.  Sometimes I don't see problems with new patches until much 
later, after I thought I had wrung it out pretty well.  ;)

The bigger problem I'm facing right now is mounts dropping and not 
remounting until a HUP signal is sent to the daemon.  I've hacked around 
this by setting up a cron job to send the HUP on an hourly basis, but 
this is far from an elegant solution.

The replicated server patch continues to be difficult. I'm still working 
on it. I'll post another replacement with an explanation tonight. 
Hopefully I've got the last of the problems with it.

And it looked so inocent it couldn't cause side effects!

For 2.6 it looks like it is very soon. Andrew was ready to pass it on 
except I got the last minute jitters after your thought provoking mail 
about the differences between 2.4 and 2.6.

Re: Please help - cleanup

I ran this on 40 clients last evening through our normal regression runs
(9 hours, 1.5T of data, 127 mount points) and found that it behaved as
expected.

I also think that it would be nice to have some form of
regressions/tests to help validate.

I should clarify, the mount dropping problem I mentioned in my last 
message is not specifically related to testing autofs-4.1.2-5 (or any 
4.1.2, I think).  I've got 4.1.1 rolled out and those systems are the 
ones dropping mounts, at least at this point in time.  My intention is 
to find a autofs release or set of patches that fixes this behavior 
sooner rather than later as it is causing problems for my users.

Just for my sanity, can anyone help me confirm the following "facts" 
about earlier behavior of the autofs-4.1.0pre10 release:

1.  NIS maps were not cached by the automounter daemon
2.  changes made to the maps and pushed out went into effect 
immediately, regardless of whether or not the changes were new key/mount 
entries to an existing map or just changes to existing key/mount pairs 
withing an existing map.

> I also think that it would be nice to have some form of

I think it's time to start developing some.  Since Red Hat tests their 
software before they ship it, maybe they have a suite already in place 
that they could share? ;)

Heh.  Wishful thinking.  Part of the reason I started pushing out test rpms
was to get more testing in environments I couldn't possibly reproduce.
That's not to say autofs doesn't get tested in-house.  I certainly do as
much testing as possible before pushing packges into a release.

I would also like to see an autofs stress test and regression test.  I
think it would help immensely.  However, setting aside time to do the work
is always the issue.

Re: Please help - cleanup

I thought that in the past someone from sun had piped up saying that
sun was trying to fix up autofs.  I'd imagine that they've got
something they can test with.

So your machines are not droping mounts. They just don't know about them, 
right.

Good morning.
I'm writing from Barcelona and English is not my born language, so I'd 
like to apologize in advance for any possible mistakes in my text.

I'm a Windows user who has recently moved to Linux (Ubuntu 10.04), and I 
have a serious problem regarding my Hard Drives' File System.
I have a desktop version of Ubuntu and I'm a complete regular user.

I have two physical drives in my system:
1. 36GB: EXT4 partition for /, another EXT4 for /home and a SWAP one.
2. 1TB (for data) drive.

I generate so much video and music data per month (AVI, MKV, MP3, WAV) 
because of my job, and need to copy it to external hard drives to ensure 
I don't lose any of it.

My question is about the FS to use in these data drives.
I currently have all of them in XFS fyle system. Every file I generate 
is saved in my internal XFS drive, and whenever the hd is almost full I 
copy the important files to External Hard Drives which are also 
formatted as XFS.

My problem comes after reading a couple of posts from 2006 in some 
forums on the web. They said that XFS is very unsecure when a power 
failure happens and recommended EXT3 (EXT4 these days I guess). They 
said that after a power failure it's very common to see data loss 
(something that never happened to me in all my years using NTFS).

As far as I know XFS is much more secure than NTFS so I don't really 
understand this issue. I assume these people were talking about systems 
which need to be continously writing to the disk, but my knowledge about 
this is very limited.

Did I chose the correct FS for my drives?


Thank you very much for your time.

Hi there,
          I am searching on what all value does di_mode of xfs_dinode_core_t
(Core Inode) hold...
If you could please help me.
          As i understand ,di_mode helps us to determine the type of file
stored in the Inode.I just wanted to know what are the mode types of
file,directory,links,etc...

Instant reply is appreciated :-)

Re: Please help...

[Sam Loy]

Thanks everyone who has tried to help so far. I am confident I will get 
it working with all of your help.

Here is some more information:
Per Marek Dohoja's reply, I added a rule to my output chain:
iptables -A FORWARD -s 192.168.1.0 - j ACCEPT.

I also tried adding 192.168.1.1 as above, with still nothing.

As suggested by Antony, I have performed the following test:

I examined the bytecounts of iptables and discovered:

Chain PREROUTING policy has accepted 11331 packets , 1345868 bytes
Chain POSTROUTING  policy has accepted 12 packets, 665 bytes, but list 
detail in 2 of the rules
	pkts = 348, bytes=25416, target=MASQUERADE  out = pp0
	pkts = 3	 bytes=144, target=MASQUERADE out=eth0: (which is 192.168.1.1)
There are a total of  8 rules under POSTROUTING, only 2 have any stats. 
Is there anyway to clear all rules and start over?
Chain OUTPUT policy has accepted 178 packets, 7838 bytes.

ping and traceroute test:

 From the firewall machine:

Can ping and traceroute www.abcnews.com. traceroute does NOT show the 
route going through 192.168.1.1, but straight to the ip address 
currently assigned ppp0. Which brings me to another subject: I am sure 
I told adsl-setup to leave the connection up continuously, yet it drops 
and re-acquires a new ip every minute. This will make any attempt to 
access my LAN from outside futile. Any suggestions on how simply 
acquire an ip from my isp and hold it forever would be greatly 
appreciated.

 From a client machine, I can ping 192.168.1.1, I can also ping the ip 
assigned by my ISP (if I type fast! see above :-) When I do a 
traceroute from my client to the ISP ip, it DOES go through 
192.168.1.1.

HOWEVER - I CANNOT ping www.abcnews.com OR the ip it resolves 
to(199.181.132.250) from a client machine.

After I conduct ping/traceroute test, the byte counts from the -nvx 
command increase on the ppp0 MASQUERADE rule ONLY, not on the eth0 
rule...and ONLY when executed on the firewall machine. The byte counts 
do not change at all when test executed from the client machine.

Routing Table:
When ppp0 is up: (Again, ppp0 is reconnecting every 60 seconds...make 
it stop! :-()

Dest				GW			Mask				Iface
(ISP assigned IP)   0.0.0.0		255.255.255.255		ppp0
192.168.1.0	      0.0.0.0			255.255.255.0			eth0
169.254.0.0            0.0.0.0                   255.255.0.0			eth0
127.0.0.0		      0.0.0.0			255.0.0.0				lo
0.0.0.0		      (ISP assign IP)     0.0.0.0				ppp0

I hope this is enough information.

By the way, Dick St. Peters, I tried your suggestion and it had no 
effect.

Thank you all again.

Sincerely,

Sam Loy

well 0/0 is exactly right. that just means the whole internet.

What are your other chains setup as?

Linux 9!?   Wow - I've only just upgraded to version 2.6 :)

Sounds pretty standard so far....

How are you testing it?

A more useful command in this case would be "iptables -L -t nat -nvx", because 
the -v option shows you the interfaces applying to the rules as well.

> Don't get it - Do I need to manually add a route?

Probably not, but what does your routing table show anyway?

Here are some things to test - in order:

1. Can you access anything out on the Internet from the firewall machine 
itself?   (Ping, traceroute would be good tests - by IP address if you don't 
have DNS resolving hostnames yet)

2. Do you have any rules in the FORWARD chain (and what is the FORWARD default 
policy)?

3. If you try a traceroute from a machine inside your LAN to an address on the 
Internet, what is the result?

4. After whatever tests you are trying, what does "iptables -L -nvx; iptables 
-L -t nat -nvx" show for the packet/byte counters on the rules (and default 
policies)?

You can't be too far away from a working solution - it's a pretty standard 
setup.

Regards,

Antony.

If I sound a little frustrated, keep in mind I'm now on week 2 of my 
attempt to setup linux as a firewall router on my home network. I have 
installed 3 different versions of linux, read hundreds of pages, tried 
at least 5 different configurations 20 times each....but still I cannot 
seem to share my dsl connection with my other machines.

I have 2 NICs in a Linux 9 installation. One card connects to my lan 
with a static ip of 192.168.1.1. The other connects to my DSL provider 
which dynamically allocates the ip.

I did this:

modprobe iptable_nat

# In the NAT table (-t nat), Append a rule (-A) after routing
# (POSTROUTING) for all packets going out ppp0 (-o ppp0) which says to
# MASQUERADE the connection (-j MASQUERADE).
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

# Turn on IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward


It does not work.  When I do a iptables -t nat  -n -L
It displays:

MASQUERADE all -- 0.0.0.0/0 		0.0.0.0/0

once for each time I've executed the above command. (now 7 times). I'm 
sorry, but this doesn't seem right. 0 to 0? don't think so. So I try 
different -o values - but always get the same.

Don't get it - Do I need to manually add a route? Completely befuttled 
and ready to throw in the towell.

In this case you have to contact the hardware vendor for specifications,
but at least in my experience, not many vendors are willing to part with
this information

Related question: does there exist any kind of definition of the abstract interface between the architecture-independent and architecture-dependent parts of the kernel? Or am I being naive?

Re: Please help

[nick]

I would recommend looking at the list at linux-mips@oss.sgi.com.  I am
fairly sure there is an R3k port already being worked on.  I assume the
mips3k processor you refer to is the R3k (which is very similar to the
R2k)?

I have a fundamental question:

If I have to port LINUX on to new processor. How will I get address
mapping of different devices. Some of them are available in the manual.
Ex: NVram starting address is not available.
Iam porting on mips3k.

It may sound very dumb, but Iam stuck there.

Thanks
