| + | ====== FlashMemory Plugin For OMV7 ====== | ||
| + | \\ | ||
| + | \\ | ||
| + | |||
| + | ===== Summary ===== | ||
| + | The FlashMemory Plugin was designed to make booting from USB thumbdrives and SD-cards feasible and a practical | ||
| + | alternative to booting from a hard drive or SSD. In addition to the relative low cost, using USB thumbdrives | ||
| + | enable easy [[https:// | ||
| + | options, quick recovery from boot drive failure and it saves a SATA port for a | ||
| + | data storage drive.\\ | ||
| + | \\ | ||
| + | This plugin is **REQUIRED**, | ||
| + | \\ | ||
| + | |||
| + | ==== Prerequisites ==== | ||
| + | |||
| + | * This procedure applies to amd64 ISO installations only. The FlashMemory Plugin is installed by default, during scripted installs. (R-PI' | ||
| + | * OMV-Extras must be installed. | ||
| + | |||
| + | ==== Installation ==== | ||
| + | |||
| + | For OMV7; installing OMV-Extras is accomplished by copying | ||
| + | and pasting the following wget command, on your server' | ||
| + | \\ | ||
| + | |||
| + | '' | ||
| + | |||
| + | Highlight the line above and hit **ctrl+c**. | ||
| + | **Note: | ||
| + | \\ | ||
| + | When the script is complete, OMV-Extra' | ||
| + | |||
| + | ---- | ||
| + | |||
| + | With OMV extra' | ||
| + | \\ | ||
| + | \\ | ||
| + | 1. Installation on the command line:\\ | ||
| + | |||
| + | '' | ||
| + | |||
| + | Again, paste the above into a PuTTY session command line, as described above.\\ | ||
| + | \\ | ||
| + | 2. Installation within the GUI: | ||
| + | |||
| + | The Flashmemory plugin can now be found under, **System**, **Plugins**. | ||
| + | |||
| + | ==== Configuration ==== | ||
| + | |||
| + | Configuration is not necessary. | ||
| + | ---- | ||
| + | \\ | ||
| + | ==== Why is the FlashMemory Plugin Required? ==== | ||
| + | \\ | ||
| + | === Wear Leveling === | ||
| + | Flash memory drives, like USB thumb drives and SD cards, are solid state, but their memory cells can only handle a limited number of writes before they wear out. When too many cells can no longer be written or erased, the drive’s controller may switch it to ‘read-only’ mode, meaning you can’t save new data, and the drive’s useful life is over.\\ | ||
| + | \\ | ||
| + | To make flash drives last longer, modern drives use “wear leveling.” This is a clever system used by the drive’s controller that spreads writes across all the memory cells, so no single spot gets worn out too quickly. Instead of reusing the same cells over and over, the controller picks cells that have been used less, even if they’re not next to each other. This keeps the drive working reliably for a long time.\\ | ||
| + | \\ | ||
| + | A larger drive, like a 64GB USB compared to a 32GB one, can last longer because it has more cells to share the wear. For example, a drive twice as large might last about twice as long for the same amount of writing. However, larger drives take __longer__ to back up and they create bigger backup files. For a boot drive, a 16GB to 32GB drive is a good balance of lifespan, cost, and backup convenience. | ||
| + | \\ | ||
| + | \\ | ||
| + | === The Purpose of the Plugin === | ||
| + | Most writes to OMV's boot drive are entries added to log files. These writes are very small, sometimes as little as 80 bytes, but they happen often. A write to a flash device happens in “blocks", | ||
| + | \\ | ||
| + | The FlashMemory Plugin reduces wear by collecting these small writes in memory and saving them as one larger write, flushed to the boot drive on shutdown. This can cut down the number of blocks written to the drive by up to 10 times. As a result, a drive might last up to 10 times longer, depending on how it’s used, compared to operating without the plugin. | ||
| + | \\ | ||
| + | It’s worth noting that SSDs would benefit from the FlashMemory Plugin as well.\\ | ||
