UNRAID CHANGE DISK NUMBER SERIAL NUMBER

But if there's been a change in disk configuration, such as a new disk added, the array is left stopped so that you can confirm the configuration is correct. Normally following system boot up the array (complete set of disks) is automatically started (brought on-line and exported as a set of shares).

NOTE: Your array will not start if you assign or attach more devices than your license key allows. This can be useful for troubleshooting if you ever suspect there may be a hardware-related issue such as a bad port or a think a power or SATA cable may be suspect. This means that it is possible to move drives between SATA ports without having to make any changes in drive assignments.

UNRAID CHANGE DISK NUMBER SERIAL NUMBER

Unraid recognizes disks by their serial number (and size). Note, however, that using encryption can complicate recovering from certain types of failure so do not juse this feature just because it is available if you have no need for it. Click on each disk you wish to have encrypted and toggle the filesystem to one of the encrypted options. If you wish to use this feature on your system, you can do so by adjusting the file system for the devices you wish to have encrypted. Use SSDs in a cache pool for the ultimate combination of functionality, performance, and protection. Apps and VMs benefit from SSDs as they can leverage their raw IO potential to perform faster when interacting with them.

SSD-based cache devices are ideal for applications and virtual machines.

Cache pools can be expanded on demand, similar to the array. To ensure data remains protected at all times (both on data and cache disks), you must assign more than one device to the cache function, creating what is called a cache-pool. If you only assign one cache device to the system, data residing there before being moved to the array on a schedule is not protected from data loss.

Creating a cache-pool adds protection for cached data.

Data written to the cache is still presented through your user shares, making use of this function completely transparent. It does this by redirecting write operations to a dedicated disk (or pool of disks in Unraid 6) and moves that data to the array on a schedule that you define (by default, once per day at 3:40AM).

Using a cache will improve array performance.

Most modern SSDs will work fine in the array, and even NVMe devices are now supported, but know that until these devices are in wider use, we only have limited testing experience using them in this setting. This does NOT apply to the cache / cache pool. Using SSDs as data/parity devices may have unexpected/undesirable results. Some SSDs may not be ideal for use in the array due to how TRIM/Discard may be implemented.

SSD support in the array is experimental.

If assigning dual parity disks, your two parity disks can vary in size, but the same rule holds true that no disk in the array can be larger than your smallest parity device. For this reason, it is highly recommended to purchase the largest HDD available for use as your initial parity device, so future expansions arenвЂ™t limited to small device sizes. When expanding your array in the future (adding more devices to data disk slots), you cannot assign a data disk that is larger than your parity device(s).

Always pick the largest storage device available to act as your parity device(s).

Assigning devices to Unraid is easy! Just remember these guidelines: Click on the Main tab and select the devices to assign to slots for parity, data, and cache disks. To assign devices to the array and/or cache, first login to the server's webGui.
