Hi,

Could it be possible that your problem is with grub and not with mount? By you trace I cannot understand your problem... can you explain it with more detail?

[ajoenk]

thank you for responding
apologize in advance if I mess english
in module maintenance - disk usage there are 2 pieces display
First look: dev / mapper / Arigo-root with options: rw, errors = remount-ro, usrquota, grpquota, acl
The second view: dev/sda1 with options: rw

at first view: dev / mapper / root Arigo had formed http-proxy cache of 2:15 GB but when viewed using tail access.log no TCP_HIT always TCP_MISS

so I conclude there are 3 problems that I am facing:
1. dev / mapper / Arigo-root with options: rw, errors = remount-ro, usrquota, grpquota, acl
2. why not TCP_HIT when the cache is stored in HDD
3. etc/fstab not found UIID

[half_life]

What you have shown so far looks like a perfectly normal install using LVM.  Perhaps taking some time and talking about squid settings are in order.  Are you saying that you are not getting hits on the cache?  Or are you saying that you feel too much is being pulled from the internet and not enough from the cache?

[lotomas]

I agree with half_life, it seems a normal LVM installation. The Arigo-root is a 'logical volume'. If you want to see the information about LVM filesystem you must use the commands: pvdisplay, vgdisplay and lvdisplay. The options of the /etc/fstab are seems normal too.

When you use LVM filesystem you cannot use the typical /dev/sda, instead of this you will use /dev/mapper/Arigo to make a reference to the "classic" /dev/sda. There is an exception, as you can see, the /dev/sda2 partion contains the /boot/ data, because /boot cannot be contained into a LVM volume. I think the UUIDs of your fstab are correct.

I can't understand your point 2 problem.

Cheers!

PD: where are you from? I speak Spanish also.

[ajoenk]

for half_life @Are you saying that you are not getting hits on the cache? <<--- i answer YES
see in module maintenance - disk usage my http-proxy now 2.54Gb
at the module HTTP PROXY - General Setting - Cache File Size (MB) i set 10000
but if i see tail log... always TCP_MISS not TCP_HIT i don't understand why?

[ajoenk]

for lotomas
i will try what u say.... but how to remove the option: errors: remount-ro, usrgroup, grpquota, acl??

because it's what makes me always TCP_MISS caching?

PD: i speak indonesian (BALI)

the problem for point 1 and point 3 is solved by means of zentyal reinstall using the expert install

the point of point 2 is: why if seen from sudo tail-f/var/log/squid3/access.log all that is visible is TCP_MISS never though TCP_HIT
When viewed from the module maintenance-disk usage-HTTP Proxy in volume is always getting bigger?

where this is the case? But how to install it following the instructions of zentyal documents on the web

do I have less in the setting of zentyal?

someone please help solve this problem .... thank you

[half_life]

Try this:

Code: [Select]

sudo grep TCP_HIT /var/log/squid3/access.log|wc -l
It will spit a number

Code: [Select]

sudo grep TCP_MISS /var/log/squid3/access.log|wc -l
This will also spit a number.

Could you post the results here?

[ajoenk]

root@arigo:/home/jlank# sudo grep TCP_HIT /var/log/squid3/access.log|wc -l
0

root@arigo:/home/jlank# sudo grep TCP_MISS /var/log/squid3/access.log|wc -l
28023

    what information should be displayed to master linux on this forum that can help?

If I am reading your config files correctly  you are setup for transparent proxy and single sign on? Are machines behind the Zentyal machine able to access websites?  I am not a squid guru at all but I will try to help until a guru arrives.

[christian]

hum.... I didn't look at configuration details but definitely, transparent proxy and authentication do not go together.
If you do need authentication, then you must use explicit proxy.

for sentences marked in italics, I said yes machines can access the website with the above conditions
for sentences that are marked in bold, where u come from half_life? Indonesian seems that you type it

[ajoenk]

huhft ... so the question is, how does that change the transparent proxy and authentication NOT together in this my case?

explicit intent proxy? how does it apply?
I've tried some changes but the result is the same, it makes me frustrated and forget to shower.

below I include the squid.conf that I have tried with the same result
