So, while having a week away in the lake district just gone, I notice on Friday that all my email alerts for my home network and more importantly this web server! Stopped flooding my Inbox, now some might say that this might be a small relief, however as I was on holiday I decided there was A) Nothing I could do remotely and B) When I get home to check the firewall and resolve said issue. Now I should add that for the last couple of week’s I’ve been noticing more and more network drops, basically, for no apparent reason the WAN Link would just drop, no errors or warning just *poof* gone. For the Network Infrastructure people reading this, they will jump to the “Owh its a SPOF (Single Point of Failure)<\/span>“<\/em> having only one WAN Connection and no redundancy or 3\/4G backup. and so on.
Yes I realise this, and it may change after this blog post and spat of outages, but as there’s currently financial return from this project\/network it’s not a major problem just an annoyance. <\/p>\n\n\n\n

Anyway that aside, prior to leaving for the Lake District I installed smartctl<\/em> on the OPNSense Firewall and ran some checks and found the following. <\/p>\n\n\n\n

sudo pkg install smartmontools<\/code><\/pre>\n\n\n\n

So my temporary solution to resolve this issue until I replace the physical firewall was to purchase a Crucial BX500 120Gb 2.5″ SSD (Amazon Link<\/a>) <\/p>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
 and a 3.5″ to 2.5″ Conversion Tray Kit (Amazon Link<\/a>) <\/p>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
After 45 Minutes of De-Racking the Firewall, it was time to open the Sophos UTM Unit, give it a spring clean and replace the failing Western Digital Hard Drive.<\/p>\n\n\n\n
A Top-Down View of the Sophos UTM 220 (Data Sheet Download<\/a>)<\/p>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
Amazon Purchases arrived, Quick Photo before installation.<\/p>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
SSD Installed into Conversion Tray, ready for the soft test to ensure that the Motherboard actually detects the SSD.  – SPOILER: It was detected!!<\/p>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
 After Replacing the disk, I downloaded the latest version of OPNSense, created a bootable USB using rufus<\/a>, ran through the installation process.  Once the base installation of OPNSense was completed, I Logged in configured the WAN Interface for the BT Business Line and then wanted to check the status of the new Crucial SSD.  By Default, the ‘smartmontools’ is not installed on the FreeBSD Firewall, so I used the following command: <\/p>\n\n\n\n
sudo pkg install smartmontools<\/code><\/pre>\n\n\n\n
Once ‘smartctl’ was installed, I ran the following command to find out where the Crucial SSD was mounted to:<\/p>\n\n\n\n
sudo smartctl --scan\n<\/code><\/pre>\n\n\n\n
The scan reported the following mount location: <\/p>\n\n\n\n
\/dev\/ada0 -d atacam # \/dev\/ada0, ATA device\n<\/code><\/pre>\n\n\n\n
then using smartctl -i \/dev\/ada0<\/em> Iclear was able to obtain the following information<\/p>\n\n\n\n
smartctl 7.0 2018-12-30 r4883 [FreeBSD 11.2-RELEASE-p9-HBSD amd64] (local build)\nCopyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org\n\n=== START OF INFORMATION SECTION ===\nModel Family:     Crucial\/Micron BX\/MX1\/2\/3\/500, M5\/600, 1100 SSDs\nDevice Model:     CT120BX500SSD1\nSerial Number:    1921E1833763\nLU WWN Device Id: 0 000000 000000000\nFirmware Version: M6CR013\nUser Capacity:    120,034,123,776 bytes [120 GB]\nSector Size:      512 bytes logical\/physical\nRotation Rate:    Solid State Device\nForm Factor:      2.5 inches\nDevice is:        In smartctl database [for details use: -P show]\nATA Version is:   ACS-2 T13\/2015-D revision 3\nSATA Version is:  SATA 3.2, 6.0 Gb\/s (current: 3.0 Gb\/s)\nLocal Time is:    Sat Jul 13 19:45:18 2019 BST\nSMART support is: Available - device has SMART capability.\nSMART support is: Enabled<\/code><\/pre>\n\n\n\n
With that, I was happy, as I will be able to use the SMART Support to be able to monitor the life of the SSD. I then restored the rest of the config and was back in business!<\/p>\n","protected":false},"excerpt":{"rendered":"
