Using MacPorts Subversion With BBEdit

Cliff — Thu, 15 Mar 2012 16:12:31 +0000

PROTIP: If you want to use the Subversion features in BBedit, and you also like using v1.7+ of svn, you have to change the default location. Obviously this assumes that you have MacPorts installed and have used it to build and install the Subversion port.

How to Replace a Failed Drive in a ZFS Pool

Cliff — Mon, 09 Jan 2012 18:49:42 +0000

So you have a failed disk in a ZFS pool and you want to fix it? Routine disk failures are really a non-event with ZFS because the volume management makes replacing them so dang easy. In many cases, unlike hardware RAID or older volume management solutions, the replacement disk doesn't even need to be exactly the same as the original. So let's get started replacing our failed disk. These instructions will be for a Solaris 10 system, so a few of the particulars related to unconfiguring the disk and device paths will vary with different flavors of UNIX.

First, take a look at the zpools to see if there are any errors. The -x flag will only display status for pools that are exhibiting errors or are otherwise unavailable.
Note: If the disk is actively failing (a process that sometimes takes a while as the OS offlines it), any commands that use storage related system calls will hang and take a long time to return. These include "zpool" and "format", so just be patient; they will eventually return.

# zpool status -x

 pool: data
 state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
        repaired.
 scrub: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        data        DEGRADED     0     0     0
          mirror-0  DEGRADED     0     0     0
            c1t4d0  ONLINE       0     0     0
            c1t5d0  FAULTED      1    81     0  too many errors
          mirror-1  ONLINE       0     0     0
            c1t2d0  ONLINE       0     0     0
            c1t3d0  ONLINE       0     0     0

errors: No known data errors

So we can easily see that c1t5d0 has failed. Take a look at the "format" output do get the particulars about the disk:
# format

Get your hands on a replacement disk that is as similar as possible to a SEAGATE-ST914602SSUN146G-0603-136.73GB. I was only able to dig up a HITACHI-H103014SCSUN146G-A2A8-136.73GB, so I'll be using that instead of a direct replacement.

Next, use "cfgadm" to look at the disks you have and their configuration status:

# cfgadm -al

Ap_Id                          Type         Receptacle   Occupant     Condition
c1                             scsi-sata    connected    configured   unknown
c1::dsk/c1t0d0                 disk         connected    configured   unknown
c1::dsk/c1t1d0                 disk         connected    configured   unknown
c1::dsk/c1t2d0                 disk         connected    configured   unknown
c1::dsk/c1t3d0                 disk         connected    configured   unknown
c1::dsk/c1t4d0                 disk         connected    configured   unknown
c1::dsk/c1t5d0                 disk         connected    configured   unknown

We want to replace t5, so we prepare it for removal by unconfiguring it:

# cfgadm -c unconfigure c1::dsk/c1t5d0

The "safe to remove" led should turn on and you can pull the disk, remembering to allow it several seconds to spin down. Replace it with the new disk and take a look at "cfgadm -al" output again to ensure that it has been automatically configured. If it has not, you can manually configure it like below:

# cfgadm -c configure c1::dsk/c1t5d0

Now, it's a simple matter of a quick "zpool replace" to get things rebuilding:

# zpool replace data c1t5d0

You can use the output of zpool status to watch the resilver process...

How to Enable SSL for CSWapache2

Cliff — Fri, 20 Aug 2010 17:56:43 +0000

If you've spent any time at all around Solaris 10, you know that Sun has invested a fair amount of effort developing a pretty snazzy Service Management Facility (SMF). It is extremely flexible and feature rich, but it's not quite as strait forward as the old legacy /etc/init.d scripts. If you're running the OpenCSW Apache package, it installs a Service Manifest into the SMF, so you'll have to edit this to run Apache SSL... Here's how:


# svccfg

svc:> select cswapache2
svc:/network/http:cswapache2> listprop httpd/ssl

httpd/ssl  boolean  false

svc:/network/http:cswapache2> setprop httpd/ssl=true
svc:/network/http:cswapache2> exit

Now, make the changes active:


# svcadm disable cswapache2
# svcadm enable cswapache2
# svcprop -p httpd/ssl svc:/network/http:cswapache2

false

# svcadm refresh cswapache2
# svcprop -p httpd/ssl svc:/network/http:cswapache2

true

Courtney points out that urlesque has a post entitled "7 Great Wes Anderson Parodies". I found Wes' work through Rushmore and he immediately became my favorite film director of all time! Having joined the creative ranks of Alfred Hitchcock, Orson Welles and Mike Nichols, imagining what movies like Spiderman or The Lord of the Rings may have been like under his unique style of direction is really quite fun!

Anyhow, visit the Urlesque post for a complete list... My favorite is the Spiderman parody.

ZoneType.sh Version 2.0

Cliff — Tue, 26 Jan 2010 17:29:29 +0000

We just started supporting Solaris 10 in our VMware cluster so I had to update my zone type script to detect if the OS is running there. I'm not sure how I feel about depending on the output of ptrdiag since the interface is labeled "unstable", but it works for now, and I really don't see Sun changing the first line of output where the system configuration is listed. Anyhow, when issued with the -v or --vmware flag, the script returns 0 if it's running on the cluster and 1 if it is not.

Usage:

# zonetype.sh -g or --global
Return 0: The machine is a global zone with 1 or more local zones
Return 1: The machine is not a global zone

# zonetype.sh -l or --local
Return 0: The machine is a local zone
Return 1: The machine is not a not a local zone

# zonetype.sh -v or --vmware
Return 0: The machine is running on a VMware hypervisor
Return 1: The machine is not running in VMware

#! /bin/bash
#
# When issued with the -g or --global flag, this script will return:
# 0 if the machine is a global zone and has one or more local zones.
# Otherwise, it will return 1
#
# When issued with the -l or --local flag, this script will return:
# 0 if if is a local zone and 1 if it is not
#
# When issued with the -v or --vmware flag, this script will return:
# 0 if it is a vmware host and 1 if not.

WP Error: The data could not be converted to UTF-8

Cliff — Wed, 23 Dec 2009 01:27:23 +0000

If you've just upgraded to WordPress 2.9 and you are now getting UTF 8 conversion errors on your dashboard, you'll need to take a look at WordPress Trac Ticket #11219.
RSS Error: The data could not be converted to UTF-8
The bottom line is that you'll need to enable either iconv or mbstring in your PHP configuration. I'm using CoolStack on Solaris 10, so it was a simple matter of uncommenting the following lines from /opt/coolstack/php5/lib/php.ini and restarting apache. While you're at it, may as well uncomment ctype as well since the new image uploader needs it.

Uncommnet the following lines in /opt/coolstack/php5/lib/php.ini.
extension=iconv.so extension=mbstring.so extension=ctype.so

Finally, restart apache:
svcadm restart apache22-csk

UNIX – Find Files that Changed Within Time Window

Cliff — Mon, 02 Nov 2009 18:57:56 +0000

Every so often us lowly UNIX admins find ourselves needing to search a file system for files that have been created or changed within a certain time window. In other words, those files that are newer than time "X", but not newer than time "Y". There are a number of ways to accomplish this, but my preferred method is to create two reference files to indicate the beginning and end of my window and use the "-newer" and "! -newer" flags to search for files that changed within that window.
# touch -amt 200910260000 /tmp/starttime # touch -amt 200910262359 /tmp/endtime # find / -type f -newer /tmp/starttime -a ! -newer /tmp/endtime
The guys at virtuelvis.com point out that it is more elegant to accomplish this without creating two files, but their solution does not work with operating systems that use strict POSIX compliant "find" implementations, making it of little use in some cases. For the curious, here is their example:
# find . -type f -newermt 2009-10-26 ! -newermt 2009-10-27

Arduino Resources for the n00b

Cliff — Wed, 14 Oct 2009 21:08:16 +0000

Lately I've been entertaining myself by building a rebreather loop controller using the Arduino micro controller. This little open source board is really nice to work with for a number of reasons. Unlike many of the alternatives which employ proprietary programming languages, the Arduino simply uses "C". It also has an IDE that runs the my Mac, and it enjoys an enormous development community.

I'm pretty new to this kind of thing, so I've been using web tutorials to work my way up from the most basic blinking LED to something that actually monitors oxygen sensors and populates an LCD with information. Some of the more valuable resources I have used are as follows:

The Banana Slug is not a Mythical Creature

Cliff — Fri, 01 May 2009 06:27:55 +0000

OK, so I never actually believed that they were a mythical creature, but it took me so long to actually find one after moving to Santa Cruz that I had great fun telling those who didn't know better that they were figment of the collective local imagination. Courtney, who had seen them before, always sighed, rolled her eyes, and reassured whatever unwitting soul I happened to be talking with at the moment that they did exist, and that I should absolutely not be taken seriously. On this point, I cannot disagree with her, but I must have been somewhat convincing because her mom actually sounded surprised when a friend finally pointed one out to me and I managed to snap a picture of it. She actually made me send her the picture because she didn't believe me.

A few banana slug facts:

They are native to the Northwest
The are HUGE! Some have reached 10 inches in length, and weights of a quarter of a pound.
They were almost the official mollusk of California. Yes, the legislature actually voted in the noble slug, but the Governor vetoed it.
They are the official mascot of UC Santa Cruz.

Useful MySQL Commands

Cliff — Fri, 01 May 2009 02:45:21 +0000

There are a lot of usefully MySQL commands that I either don't run enough to remember or just end up using some GUI to accomplish. Nothing against Navicat, but what kind of sysadmin would I be if I couldn't do it at the command line as well. Anyhow, I had to do a bunch of this kind of work lately, so I thought I would write the more common commands down here so I would have them to reference.

It is generally a good idea to firewall off your MySQL port (3306) unless you are on a secure network. The downside to this is that it prevents you from using GUI tools like Navicat to connect to your database server. No problem, just use this command to SSH tunnel a connection. After doing this, you can connect to your database on localhost port 8888:
ssh -fNg -L 8888:127.0.0.1:3306 login@mysql-server

Once you have installed a new instance of MySQL, you have to change the root password:
# mysql -u root mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd'); mysql> SET PASSWORD FOR 'root'@'yourhostname' = PASSWORD('newpwd'); mysql> exit

Depending on the way you handle your MySQL installation, you will most likely have to run the mysql_upgrade script after upgrades to use all the new features:
mysql_upgrade -u root â€“password=yourpassword

Do a thorough check to see if your tables are corrupted:
mysqlcheck -u root -p --check --extended --all-databases

Repair any corruption if it exists:
mysqlcheck -u root -p --repair --all-databases

Look at all your tables and optomize them if necessary:
mysqlcheck -u root -p --optimize --all-databases

Script to Determine Solaris 10 Zone Type

Cliff — Tue, 03 Mar 2009 22:46:27 +0000

We use a lot of local zones in our Solaris 10 environment. We also use cfengine pretty heavily and there are some instances when we need to include or exclude certain automated tasks based on what type of zone we are working with. I wrote this little script that checks to see what type of zone we are dealing with. Based on the return value, I can set a cfengine class and control what gets run and where.

Return 0 if the machine is a global zone with 1 or more local zones
Return 1 if the machine is either a local zone or a global zone with 0 local zones

#! /bin/bash
#
# When issued with the -g or --global flag, this script will return:
# 0 if the machine is a global zone and has one or more local zones.
# Otherwise, it will return 1
#
# Wen issued with the -l or --local flag, this script will return:
# 0 if if is a local zone and 1 if it is not

Check Speed / Duplex on Solaris 10

In the past, I always had to use the ndd - get command to figure out what my link speed and duplex settings were. In Solaris 10, Sun now gives us the handy dladm command, which makes it a whole lot easier.
