Installation and Upgrades / Boot errors
« on: September 18, 2010, 08:59:29 am »
Just after the BIOS hands over to Zentyal 2.0.1 to boot I get two messages on screen, vis:
error: no suitable mode found
error: unknown command 'terminal'
After a pause Zentyal then boots and seems to work normally.
On shutdown Zentyal closes but leaves me with a Linux terminal prompt and messages about squid, which causes shutdown to hang.
Any ideas?

Installation and Upgrades / Re: v2 RAID module
« on: September 04, 2010, 11:02:14 pm »
I think in the article the author is creating two arrays - a RAID 1 (md0) on the first disk partitions and a RAID 10 (md1) on the second disk partitions.
You may be right that the array wasn't correctly set up - the only example I've found is the linuxguide one which deals only with two disks so there may be an extra step involved if there is a third disk. As seems often to be the case with Linux mdadm seems to have been put together by genius geeks who never bothered very much about letting folk know what they've done, as it works for them!
However I built the array using cfdisk on a live Linux CD and mdadm seemed quite happy with the array before I left it. I then installed Zentyal using the downloadable iso which of course meant having to deal with the Ubuntu install partitioner, which it seems doesn't know anything about RAID 10 but still insisted on wanting to set up the disks for me anyway. I strongly suspect the problem arose then as there seems to be no way of just telling the partitioner to leave things as they are.

This sounds strange to me as I would expect a Raid 10 to have (at least) 4 disks.
No, you can build a Linux RAID 10 with an odd number of disks - I'm told:
http://www.linuxplanet.com/linuxplanet/tutorials/6514/1/
and see also:
http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10
I followed the linuxplanet tutoral in creating the 3 disk array and as far as I could tell it was working when I installed Zentyal to it.

To clarify your situation please post the output of "cat /proc/mdstat" and of "mdadm -D /dev/md0" for all arrays.
Best regards
OK. Herewith:

As you'll see from that the array was working -and synching - with three active disks. It was only after I enabled the Zentyal RAID module that it apparently decided to drop one and resynch with two. The array size given in mdadm -D /dev/md0 of 15GB is also correct given that it is striped across three 10GB disks and a df done now still shows /dev/md0 with size 14GB, used 2GB available 12GB.

Installation and Upgrades / v2 RAID module
« on: September 04, 2010, 06:26:50 am »
I've just installed Zentyal 2.0 on a Linux software RAID 10 array with three disks (/dev/sda1:/dev/sdb1:/dev/sdc1)
mdadm confirms all three disks are active in the array.
The Zentyal dashboard module correctly identifies the array as /dev/md0 and RAID 10 but says there are only two disks in the array - /dev/sda1 and /dev/sdb1.
Will this cause problems?

« on: September 04, 2010, 06:20:36 am »No, you don't need two identical disks. I'm running Linux software RAID 10 on three disks, 2 @10.2GB (1 x Seagate, 1 x Western Digital) and the third is 80GB with a 10.2GB primary partition included in the array.

Oops, my bad. Forgot to add the new Zentyal network to the 'proxy ignore' list in Firefox. Please do not read this thread.
Well, Zentyal 2 still seems awfully slow but I'll give it a chance.
ps. The URL is still https://{Zental_box_IP}/ebox

Installation and Upgrades / No web admin in 2.0
« on: September 02, 2010, 05:36:37 am »
I'm new to ebox/Zentyal, having downloaded v2 just this morning. First impressions:
Installation eventually completed, but several times seemed to stop for so long that I thought it had hung. Something to indicate that it hasn't would be useful.
Zentyal takes far longer to boot that any Windows OS I've ever used. Nearly five minutes between the BIOS handing over to the boot loader and the log-on screen appearing! OK, it's only a 1200MHz test machine with limited RAM, but that's quite unimpressive given the time Ubunbtu Server alone boots on the same machine.
I installed with only one NIC, which was apparently marked 'external' by the installer. Now I have installed a second NIC and configured it internal but I cannot access the admin web page from Firefox. I tried https://{zentyal_ip}, https://{zentyal_ip}/ebox and https://{zentyal_ip}/zentyal but there's no response from the server. However I can log into Ubuntu via PUTty, so the network is correct.
If there's a control panel for administrator access I'm damned if I can find it.

Installation and Upgrades / RADIUS accounting
« on: September 01, 2010, 06:45:10 am »
Hi. I haven't seen eBox/Zentyal in operation yet as I'm waiting to download v2.0 for a look-see.
However I've read the documentation on eBox 1.4 and have at least one question.
Will Zentyal be able to handle RADIUS accounting?
Essentially the Radius client will send accounting packages to port 1813 every x minutes detailing the bytes up- and down-loaded by each logged-on user through their PPP tunnel. I've no experience with LDAP (I've what I need running on MySQL) but I'll need to be able to set it to accept these accounting packets and keep a accumulating record of usage.
If this functionality is available I think I'll find Zentyal very useful.

Installation and Upgrades / VirtualBox image?
« on: August 31, 2010, 04:18:48 am »
The link in the downloads page to the eBox VirtualBox image .iso at Sourceforge leads to a "no such file" response from Sourceforge. Is the image available anywhere else?
