Solaris 10 on x86 refuses to boot after exporting raw iSCSI volumes

April 28th, 2013 by Andre van Eyssen

Quick case notes for those who run into the same thing:

Export some raw devices through iSCSI. All are functional and well behaved. Create a zpool on said LUNs from the client machine. Still functional. Reboot the server, locks before displaying grub menu. Notably, these LUNs previously had a zpool on them.

There appears to be an issue with grub’s attempt to locate the root filesystem using ¬†findroot.

The LUNs were previously used (and labelled) by zpool during testing. The combination of partial zpool and the EFI label seems to be the problem. Clean the partition off and replace with a SOLARIS2 partition tag and try again; the grub problem goes away.

There’s obviously room for deeper analysis here, but I’m just throwing this note up in case somebody else hits the same oddity.

Illumos-Joyent patch tree – Joyent releases a slab of code for Illumos

April 16th, 2011 by Andre van Eyssen

For those not lurking the mailing lists, Joyent have opened their first real
block of code. New features include:

* ZFS I/O fair-share scheduling for zones
* the Joyent brand, which can be used as a template for other non-SysVR4 or
IPS zone brands
* Reintroduction of sparse zone images
* Crossbow vnics on demand for zones & non-unique vnic naming (unique per
zone, not per system)
* svcs enhancements ( svcs -Z/-z for interrogating zone services, -L for
outputting log files directly (no more ls /var/svc/log | grep… ))
* vfsstat and iostat tweaks and ziostat, iostat(1M) for ZFS I/O
* more per-zone IO kstats
* the zonemon utility for zone kernel state troubleshooting
* DTrace enhancements such as llquantize

You can get digging through the code at:

Colour man pages on Solaris

November 17th, 2010 by Andre van Eyssen

In followup to a discussion with Boyd, here’s how to make man pages more visually pleasing on Solaris – well, at least more colourful. This should work on other platforms with less available, too — but I’ve only tested on Solaris.

First up, set your pager to be “less”:

  • PAGER=/usr/bin/less

Then set up some environment variables to instruct less to cope with colour

  • LESS_TERMCAP_mb=$’\E[01;33m’ # blink, start
  • LESS_TERMCAP_md=$’\E[01;31m’ # bold, start
  • LESS_TERMCAP_me=$’\E[0m’ # end mode
  • LESS_TERMCAP_se=$’\E[0m’ # standout-mode,end
  • LESS_TERMCAP_so=$’\E[01;41;33m’ # standout-mode,start
  • LESS_TERMCAP_ue=$’\E[0m’ # underline, end
  • LESS_TERMCAP_us=$’\E[01;32m’ # underline, start

Before:

less monochrome

After:

less colour

VDI Bug – failure with iSCSI errors

October 6th, 2009 by Andre van Eyssen

For some reason, after a reboot the Solaris iSCSI target daemon comes up with a blank list of targets even though the shareiscsi property on the zvols are set correctly. To fix, “svcadm restart iscsitgt” and the problem will clear immediately.

After the conference

July 21st, 2009 by Andre van Eyssen

It’s post-KCA now and there’s still a buzz around and people are talking and enjoying stories and recounting presentations.

All in all, it was an excellent conference and I think James did an excellent job to pull together such a great event with limited resources and time.

These conferences are often the one time we can get together to put face to name – all those people who change from email addresses and IRC nicks to real people (at the pub, no less!).

There are some snapshots of the speakers up at http://mexico.purplecow.org/static/kca_spk/ for those who are interested.

Oracle buys Sun

April 20th, 2009 by Andre van Eyssen

Well, I’m sure you’ve probably already heard, but Oracle has moved to acquire Sun Microsystems at $9.50/share.

http://www.sun.com/third-party/global/oracle/index.jsp

Amazing to see the turn-around in El Reg, too – http://www.theregister.co.uk/2009/04/20/oracle_buys_sun – perhaps they’re scared Larry will be upset if they kept their usual attitude rolling?

I, for one, am hopeful that this announcement will lead to more great servers running a great operating system and a solid database.
