Comment on OpenSolaris Update to Build 90 by Serguei Zhitinski

Serguei Zhitinski — Mon, 16 Jun 2008 20:36:25 +0000

Thaks a lot!

I’ve upgraded to 90 from GUI Package Manager and after that OpenSolaris failed to boot.
So I’ve booted from LiveCd, mounted hard disk and did what you typed above.
Everything is OK after that.

Thanks again! I was crying already about my lost data….

Comment on Free Digital Signature For ALL Danes by olga

olga — Thu, 01 May 2008 10:14:59 +0000

In many European countries the government now as you said “understands technology” and it’s a great change for the people, I wish more countries will follow.
If you’re interested, there’s some useful background (non-commercial) information about digital signatures at http://www.arx.com/digital-signatures-faq.php

Ah, and I see from the Trac comments that you were instrumental in the final fixing (after you’d written this post, but before I checked in the repo). So lildude++.

Utils::glob calls system/classes/utils.php, so it is fixed

Comment on Habari: First Impressions by Colin

Colin — Mon, 28 Apr 2008 09:12:13 +0000

Erm, no it’s not. I’ve just checked out r1584 and it’s still there in system/classes/themes.php on line 48:

48 if ( $screenshot= Utils::glob( $theme_path . '/screenshot.{png,jpg,gif}' , GLOB_BRACE) ) {

It’s certainly fixed in other places, like system/classes/utils.php

This was really helpful, thanks! One (really minor nit), you should add an instruction to uncomment one of the htaccess authentication methods, that tripped me up for a minute.

The GLOB_BRACE bug is fixed in SVN for a while, so the new release will not have that bug any more. You could also try running bleeding edge Habari, from http://habariproject.org/dist/habari_head.zip - it may be broken in other ways, but that’s always the latest code.

Comment on HOWTO: Multi-boot Solaris, RHEL, SLES and Nevada by Colin

Colin — Fri, 25 Apr 2008 09:25:20 +0000

Hi Dean

I think you’ve incorrectly specified your boot_device setting. Try leaving off the p# part. The Solaris installer will only find the one partition, so it’ll only install on that partition.

See http://docs.sun.com/app/docs/doc/820-4042/preparecustom-113?l=en&a=view for more details.

Cheers,
Colin

Comment on HOWTO: Multi-boot Solaris, RHEL, SLES and Nevada by Dean Russell

Dean Russell — Thu, 24 Apr 2008 20:03:48 +0000

Hi Lildude,

I have been trying, did I say TRYING, to setup a dualboot install on a single disk in a X2200. The OSs are SLES 10 SP1 x86-64 RC5, installed first via AutoYast and Sol10 x86 update5 build6. The problem I am creating (I say I because I am the only one doing this and there is really no one else to blame) is after SLES goes in first, just fine by the way…boots and everything, the follow up Sol10×86 install fails due to the disk not being found/correct/addressed in /dev/rdsk. Sigh! The fdisk under SLES shows /dev/sda2 as type BE and the fdisk under Sol10 shows the disk as Solaris Boot (even though it does not grace one with a hex or a decimal type). Did I say SIGH yet?

Steps being taken:
1) create SLES install with AutoYast, edit XML to add partition type of 190 (hex BE) for partition 2
# fdisk -l

Disk /dev/sda: 250.0 GB, 250056000000 bytes
255 heads, 63 sectors/track, 30400 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 1 7 56196 12 Compaq diagnostics
/dev/sda2 8 13062 104864287+ be Solaris boot
/dev/sda3 13063 30400 139267485 f W95 Ext’d (LBA)
/dev/sda5 13063 13193 1052226 83 Linux
/dev/sda6 13194 26248 104864256 83 Linux
/dev/sda7 26249 27292 8385898+ 82 Linux swap / Solaris

2) commonsense with SLES install, looks good so far (remember the boots and everything)
3) attempt to run jumpstart to install Sol10×86, starts to install but fails on the boot disk that is specified
Begin script install_begin execution completed.

ERROR: Field 2 - Invalid disk name (c1d0p2)
Solaris installation program exited.
#

format only sees c1d0, it does not see and partitions like c1d0p2 and the slices in the /dev/rdsk/c1d0s2 don’t point to anything real.
Furthermore, any profile with c1d0px fails the check script in jumpstart. sigh.

I know this is a lot of partial information, there is more where that came from. Do you have any suggestions on how to get Solaris and SuSE to play nicely with each other during an automated install via Yast and Jumpstart?

Thanks in advance and as always, cheers,

Dean Russell

Feedback is always welcome. We don’t (to my knowledge) have (m)any other OpenSolaris users, so your experience and expertise would go a long way toward making Habari shine on non-GNU systems!

Join the -dev mailing list to discuss changes, or drop by #habari on irc.freenode.net to chat with us about any suggestions you have.

Alexandre Dumont — Tue, 22 Apr 2008 10:12:20 +0000

Thanks for this very good Cheatsheet.

Regarding destroying a snapshot having a dependent clone, you get the following error:

# zfs destroy local/alex@1
cannot destroy ‘local/alex@1′: snapshot has dependent clones
use ‘-R’ to destroy the following datasets:
local/clone1

I was wondering a way to be aware of all the zfs that actually are clones of a snapshot (not having to try and fail on a destroy):

I found the following way:

# zfs get origin
NAME PROPERTY VALUE SOURCE
local origin - -
local/alex origin - -
local/alex@1 origin - -
local/alex/subdir01 origin - -
local/alex/subdir02 origin - -
local/clone1 origin local/alex@1 -

–> that way you can see which zfs is clone of a snaphot.

Cheers Skippy, I think I might just do that. I need to grab a copy of the code and start dabbling and see what needs to be done to move my sites across and then I’ll see what questions and issues I have.

Habari includes a WordPress importer plugin, allowing you to pull all the live data from your WordPress blog into Habari. The default permalinks in Habari are different from WordPress’, but there exists a Habari plugin called “Route301″ that allows you to retain your old permalink structure if you so choose.

Habari, using a strong object oriented design, doesn’t load much into global scope until you tell it to do so, and then it’s only in the theme portion of the code for easier construction of PHP-based templates. One of the developers has Habari running successfully on a VPS with only 64 MB RAM, using SQLite for the datastore.

Feel free to join the -users and/or -dev mailing lists to ask any questions you might have! Or join #habari on irc.freenode.net if you need real-time support.
