Thank you! Thank you! This fixed a tailscale problem. Prior to the patch, tailscale was removed on update due to the error. Fortunately Unraid keeps the previous template, so reinstall worked easily. -- Tom

During my 6.12.8 upgrade, the interfaces did not do a link down. This resulted in the DHCP server re-assigning new IP addresses to all the interfaces on UNRAID. Once I found those, everything came up OK on the new addresses. -- Tom

The update to Firefox 113.0 has resolved the noVNC problem. It appears that 112.x.x versions have the issue. -- Tom

Speculation... If sufficient errors were detected, the link might auto re-negotiate the link speed. That might fail for 1 GbE, then retry and succeed for 100 MbE. Can you disable auto negotiation, and set the link to only 1 GbE at the router? At the server? -- Tom

Hi Mike - early on, the equipment on each end used Link Aggregation to package 4 10GE links as a single 40 GE link. This is where some issues cropped up. The ratified version of the 802.3 ba standard (June 2010) for 40GE & 100GE inserted something called Multi Lane Distributor (MLD 64/66b) to handle all this in hardware chips on the Ethernet ASIC interfaces ahead of the physical interfaces. (The physical interfaces generally don't know about this). Your Mellanox interface is one end, the ethernet switch that the cable is plugged into is the other end. So the question is what is the age of the equipment on each end of the link? If both ends are listed as being 802.3 ba compliant, then you should be OK. Practically most equipment took several years after the standard rataification to adopt everything. -- Tom

40GE can be a bit of a rat's nest. The physical standards are primarily 4-lane interfaces (4 copper lanes, or 4 optical lanes). That usually makes the transceivers a bit expensive. Many of the initial deployments of 40GE used it as 4 independent 10GE links with a special break out cable arrangement. This was done as a way to increase the density of 10GE interfaces on a piece of equipment, not as 40GE links. For 40GE use those usually had link aggregation (x4) to treat the bundle as a single 40GE point-to-point. If your application is as a single-40GE-link (which is what it sounds like), you need to be concerned with compatibility of the two ends, both physically and with link aggregation compatibility. Expect to need a fair amount of configuration effort. There were a number of link aggregation issues back in the 2010-2015 time frame where the two ends just would not talk between vendors. Whether older equipment was eventually harmonized I don't know (and is probably vendor and model number dependent). -- Tom

Found the problem. It appears the VNC VM GUI display does not play well with Firefox 112.0.1 on the Ubuntu client. The previous days version of Firefox worked fine, so likely the latest update (I think this is the most current version). I cleared browser cache on the Firefox client - that did not improve anything. I launched Chrome 112.0.5615.121 on the Ubuntu client, and that works well with the VMs. -- Tom

Hi JorgeB - thanks for the reply! Using the console to transfer large files between NVMe and HardDrives is very fast in both directions, no errors. -- Tom

This morning, all VM's (old, new, recently updated, not recently updated) suddenly are extremely slow. On 6.11.5. The UNRAID GUI seems fine and snappy, it's just the VM's. Opening a console window on a VM that worked fine yesterday brings up a sluggish console window - very very slow to resize. Running 'top' in that window VM shows nothing consuming large CPU resources or memory for that VM, adequate free space and CPU. Five or Six Ubuntu 20.04 and 22.04 VMs tried, all slow as molasses. Running Firefox in the VM is almost impossible, 10-12 seconds to respond to each mouse click, but it does function correctly eventually. All services run by VM are almost ground to a halt. Only update this morning was I think unassigned devices plugin 2023.04.17 Rebooted the server, no improvement. Server memory, disk stats look fine. Network working correctly. Docker images come up fine and the GUI is very responsive, so this seems isolated to just the VMs. Diagnostics attached. -- Tom tower-diagnostics-20230418-1000.zip

Dynamix ssd trim plugin - is it still needed? On Unraid 6.11.5 I am getting a plug-in file install error, referencing: /boot/config/plugins-error/dynamix.ssd.trim.plg The button to remove it does not work. The file is in fact in the /boot/config/plugin-error/ directory. Is this plugin still needed, or has it been superseded by upgrades to UNRAID over time? If it's no longer needed, can it just be manually deleted from the containing directory? -- Tom

Having difficulty updating to Dynamix System Statistics 2023.02.05a When clicking the UPDATE button nothing happens. Under the tab Plugin File Install Errors one item is listed: /boot/config/plugins-error/dynamix.ssd.trim.plg It shows a status of ERROR. When clicking the Remove button for that, nothing happens. Have since rebooted the server, the above does not change. There are no obvious errors in the log. The graphical stats page continues to work On Unraid 6.11.5. -- Tom

Are you accessing it via an IP address (e.g. 192.168.x.x) or via a domain name / suffix (e.g. mytower.myhomenetwork). IP addresses can sometimes be re-assigned by your router (or ISP modem/router) on reboot which perhaps might change the IP. If you are using a domain name, do you have a DNS that knows how to redirect it internally? Does that need to have it's IP updated? If your server is using static IP than that shouldn't be an issue. Are you using My Servers service? (if so, that's a bit outside my experience). -- Tom

I use Acronis for backing up various machines to Unraid. No share is mounted on Windows. In UNRAID, a new share is setup as: Public, Export=Yes, Use Cache pool = No My backup speed is not limited by the UNRAID hard drive but by Acronis, so for me there is no value in using the cache for this. In Acronis, create a new backup, and select Backup Destination. That will be Network --> name of your Unraid server (perhaps TOWER) --> Name of the public shared folder above. Acronis should (sometimes quite slowly) populate the path as you select each folder down to that new share. After the backup completes, you probably want to limit access to that newly created backup file. In the UINRAID command prompt: $ CD to the new backup file's containing directory $ chmod 444 the_backup_file_you_just_created $ chown root:root the_backup_file_you_just_created That will make the backup file read-only, and only the root login in UNRAID an change that. Acronis creates a new file for each differential backup. I prefer NOT to use incremental backup. The difference is that differential writes the backup between now and when the original full backup was done. To restore you only need the full and the last differential file to be good. Each differential file is larger as a result. Incremental writes since the last incremental backup. That means to restore you have to go back to the full, then replay all incremental backups. If one of those is damaged your restore stops at that point. But the incremental file is smaller as a result. -- Tom

You might find this Docker folder organizer to be helpful, from Ibracorp. https://docs.ibracorp.io/docker-folders/ -- Tom

There are certain ASCII characters in the filename that don't work with Rsync on Linux, rsync fails to copy the file as a result. My recollection is the vertical pipe character | is one of them, colon is another, perhaps some related to Linux file redirection such as greater-than, less-than might be others. Some of these are OK in Windows. -- Tom
