Mail / Upgrades

     After servers were rebooted, postfix did not start ont he mail server and I did not notice before I went to bed.  This affected the ability to send outgoing e-mail.

Kernel Upgrade Finished

     Kernel upgrades went smoothly.  My oldest son Carl, was visiting so I didn’t post this earlier, but only had two machines not boot up properly, mxlinux and the web server, and a reboot was all it too for them.  ALL NIS bindings and NFS mounts happened correctly the first time around so it feels like these aspects of Linux are finally maturing to the point where the are reliable.

Kernel Upgrade 3/23/21 11pm PST

     I am going to be upgrading kernels on most of our servers starting at 11PM.  If things go smoothly we should be done by 11:30PM however the last round we had a couple of machines that had a corrupted Grub configuration that had to be fixed so it took a bit longer.

Hubzilla / Web Server

     Hubzilla has caused various grief to our web server but I’ve finally chased things down to a beta worker module that was very broken.  Installed the stable version and now it seems to be behaving.

Web Server Maintenance

     I messed up during last night’s backup of the web server so need to take it down again tonight, starting about 12:15AM (Mon March 8th) for about 45 minutes to make another backup.

Nextcloud

     I will be moving Nextcloud from https://www.eskimo.com/nextcloud/ to https://nextcloud.eskimo.com/ to resolve a conflict between it and WordPress that prevents some of it’s features from working properly.

     I do not yet know the exact time and date this will happen.

Flash Database

     I managed to successfully install hardware and software.  Only drawback is that the ioFusion2 drive in some way conflicted with one of my NIC cards, so I had to move the ethernet back to the Intel controller.  The E1000 chipset drivers don’t work right with hardware offloading in Linux so it is necessary to disable it which puts more burdon on the CPU.  But I doubt it will make a measurable difference, between hosts I am seeing .1ms ping time.

     So drivers worked properly with the 5.10.20 kernel I am now running, and the utility software all installed and functioned properly, so the database is now operating off of it.  It reduced our WordPress home page load times from 240-290ms region to 207ms.  Database which used to max at 400TPS has successfully handled bursts of 2923 TPS.
