+== Employer ==
+--------------
+*Name:* [[https://fastwyre.com|Fastwyre Broadband]]
+
+| Duration of employment |            |
+|------------------------|------------|
+| Start Date             | 2022/02/21 |
+| End Date               | 2023/12/01 |
+
+== Job Duties ==
+----------------
+In my role as a Unix & Linux Systems Engineer at Fastwyre Broadband, I was deeply involved in various critical facets of our operations. I spearheaded the administration of our servers, catering to a wide spectrum of internal and external services. Additionally, my responsibilities extended to delivering robust L2 & L3 support for the myriad applications running on them. 
+
+As a Systems Engineer, I played a pivotal role in orchestrating and executing strategic projects focused on establishing new infrastructure. I spearheaded the seamless migration of both our internal systems and our valued customers from legacy setups to modernized environments. This involved meticulously planning and implementing the transition, ensuring minimal disruption while maximizing the efficiency and reliability of our systems. Collaborating cross-functionally, I worked with my team to architect robust solutions that aligned with evolving technological needs and significantly enhanced our operational capabilities
+
+In addition to my core responsibilities, I maintained a suite of legacy scripts and workflows, predominantly scripted in Perl, Python, Shell, and Bash. These played a pivotal role in streamlining our internal processes, serving as the backbone for automating a significant portion of our operations. They efficiently generated crucial data from a myriad of legacy services utilized by our customers. This data was instrumental in facilitating our billing department's accurate invoicing processes, ensuring precise customer charges based on the services availed
+
+
+== Services ==
+--------------
+=== Provided to Customers ===
+- Email ([[https://www.magicmail.com/|MagicMail]])
+- Public NTP Servers (xntpd, ntpd & chrony)
+- Legacy WebServers (apache2 & httpd)
+{{{	
+  Note:
+  These in the past hosted websites for our customers, however shortly before I 
+  started working there the company no longer offered this service to new customers. 
+  While we still continued to host some of our legacy customer's sites.
+  
+  Our webservers got shut down a few months before I left the company.
+}}}
+- DNS (named/bind9)
+{{{
+  Note:
+  The company used to offer to fully handle customer's domains and websites.
+  Meaning that we used to register their domain at a registrar and host their
+  DNS records on our public DNS servers.
+}}}
+- Telephony & VoIP ([[https://www.metaswitch.com/|Metaswitch]])
+{{{
+  Note:
+  I managed our MetaSwitch enviornment (CFS, EAS & their related Hardware & VMs). 
+  
+  This included:
+  - Setting up & configuring VoIP Phones to work with our CFS for businesses 
+  - Providing support for VoIP & SIP related issues
+  - Managed hardware maintainance (drive & unit replacements) Setting up automated (via cron) scripts to archive BAF files 
+    and transfer them to our vendors.
+}}}
+- DHCP (isc-dhpcd)
+- IPTV Managment Server ([[https://www.minervanetworks.com/platform/|Minerva 10]])
+
+=== Provided Internally ===
+- SMTP Servers (postfix configured as a relay)
+{{{
+  Note:
+  I had to setup postfix as a smtp-relay to allow for our legacy internal systems & 
+  applicatons that didn't support auth over tls or starttls to be able to send 
+  emails for both internal & customer related services.
+}}}
+- File Servers (nfs, samba, ftp, sftp, etc)
+{{{
+  Note:
+  This is a rather general/broad service, but our file/storage servers handled storing backups
+  from our various services & servers that didn't all support just using sftp. This was due 
+  to the age of some of our systems as many of them didn't suport the same hostkey algorithms
+  and/or we didn't have shell access to the underlying OS to change sshd_config to add 
+  support.

+- [[https://calix.com|Calix]] Network Management Servers ([[https://www.calix.com/compass/calix-management-system.html|CMS]] & [[https://www.calix.com/calix-university/axos/introduction-to-smx.html|SMx]])

+= ZFS Upgrade Issue =
+== Background ==
+----------------
+I have an DIY Ubuntu NAS (one of the first few linux installs), and I was having aggravations with the zfs-dkms package that I had setup a couple of years ago to host raided pools for my NAS setup. However, recently during an update I noticed the kernel was updated on the machine to 6.2.0-39-generic which now caused the zfs-dkms to throw errors when apt would run mkinitcpio as the zfs-dkms-2.1.5 module only supported up to kernel 5.19.
+
+While it didn't exactly cause any issues with the zfs installation there was currently (it still functioned fine even with the new kernel). I got tired of it so I decided to compile openzfs from source and install it on my system.
+
+{{{bash
+## Run as root
+# sudo -i 
+
+git clone https://github.com/openzfs/zfs
+
+## I was missing a few dependencies but installed them like so
+apt install uuid-dev libblkid-dev
+
+cd zfs
+## Run the autoconf autogen script
+./autogen.sh
+## Run the configure script to build the Makefile
+./configure
+
+## Build the module to make sure everything goes ok
+make 
+
+## Had to add the extra modules to the depmod search ath
+depmod_cont="$(</etc/depmod.d/ubuntu.conf)"
+## Replace "search" with "search extra" to put the extra modules into the depmod path
+depmod_cont="${depmod_cont/search/search extra}"
+echo "$depmod_cont" > /etc/depmod.d/ubuntu.conf
+
+## Build and intall
+make install
+
+## Run ldconfig
+ldconfig
+
+## Run depmod
+depmod
+}}}
+
+
+== Other issues ==
+=== Zpools not importing ===
+----------------------------
+Upon finishing installation and reboot I noticed that when the server rebooted it didn't mount the pools on boot. I always had to import them manually `zpool import data && zpool import media`
+
+I was confused because the configs setup by my dkms installation were still valid `/etc/defaults/zfs`.
+
+While it took me an hour to figure it out, I eventually figured out what was wrong and why zfs wasn't importing my pools.
+
+the services configured in /usr/lib/systemd/system were setup with the path that bsd/unix would use for the zpool.cache file (`/usr/local/etc/zfs/zpool.cache`) instead of what zfs was configured with on my zfs-dkms installation (`/etc/zfs/zpool.cache`).
+
+=== Resolution ===
+------------------
+All I ended up needing to do was change the path's that the service files from `/usr/local/etc/zfs/zpool.cache` to `/etc/zfs/zpool.cache` (wherever applicable).
+
+After doing that and rebooting the pools were imported and mounted as they previously had.
