Piwigo Photo Gallery

     In the past I recommended Coppermine but Coppermine broke with 7.2.  It really died do to lack of interest and maintenance.  The authors did not keep it up to date with modern PHP standards.

     I recently replaced my Coppermine Gallery with Piwigo.  Piwigo is MUCH more capable, it has a plugin extension method and there are around 300 plugins currently available.  It works fast and proper with our hosting facilities.

     You can get it here: https://piwigo.org/get-piwigo

     If you do not have a database setup yet, you will need one so in that case e-mail support@eskimo.com and request a database.  There is no charge for this.

     If you’d like to see how this looks, you can visit my gallery at: https://www.eskimo.com/~nanook

     If you need any help e-mail nanook@yellow-snow.net or support@eskimo.com

Hardware Work Done

     I’ve replaced the Intel NIC’s with TP-Link NIC’s.  The first machine took close to two hours because at first I was not able to get it to work.  I finally chased it down to lack of patience on my part, these cards take approximately 1 minute to initialize.

     I was not able to use the old cards in a private network as I had planned because as soon as I configured one, localhost became bound to it and broke the other connection.  I’m sure this is operator malfunction but I will need to do further research.


Hardware Maintenance Late Sept 17th to Early Sept 18th

     I will be taking various machines down tonight for about fifteen minutes each to install new NIC cards with non-Intel chipsets.  From 4.15.0 forward, the Linux kernel has had a bug in the Intel E-1000 drivers that cause the cards to lock-up when hardware offloading is used.  Usually these lock-ups are transient resulting in 2-3 second delays in data but occasionally the cards will lock hard and require a drive to the co-lo facility to physically reset the machine.

     Because the servers most affected are those carrying heavy traffic, the NFS server providing the home directories in particular, I will be replacing the NIC cards on all the NFS servers.  This will affect virtually all of our services but will prevent long down times like we suffered Sunday morning from recurring.

     I filed a bug report April of this year on this problem.  Canonical has offered me various kernels to try, many of them either did not boot at all or were extremely unstable.  At this point I feel it’s more cost effective and less service affecting just to replace the hardware.

Outage Sept 16th 2018 05:15 – 12:46

     The ethernet controller on the server that provides /home pages wedged today.  Most services depend upon being able to access /home and were unavailable as a result.

     As near as I can tell looking at the logs, the ethernet wedged shortly after 5AM but I did not receive any telephone calls until around 11AM.  I was unable to fix it from here so I had to drive to the co-location facility.

     Everything was back in service at 12:46 (afternoon).
