Unraid Delete Share

Unraid can store digital media like videos, photos, music, and movies. In the Unraid device, you can build an array of hard drives. You can share the data from those drives across the local network. Unraid keeps all the data on the drives securely. In the Unraid system, you have control over your storage.

Hey guys, new new unRAID but so far really liking it. I've had my plex server in Windows for a couple years but recently moved it to unRAID to take advantage of the parity/backup features. I have the unRAID box set up in the corner of the living room and have been accessing it's file system via network using Windows Explorer on my laptop.
Hi, I am running the latest unRAID no beta, and after deleating 2 empty shares (isos and one I created), I am seeing them come back after a reboot Press J to jump to the feed. Press question mark to learn the rest of the keyboard shortcuts.
The Unraid USB Flash Creator: The Unraid USB Flash Creator tool is an open source program digitally signed by Lime Technology, Inc. Using this program, you can easily convert almost any USB flash device into an Unraid boot device.

Ok, how do I re-partition my SSD pools?

The idea is to use the Mover to copy all data from the pool to a target device in the Unraid array. Then erase all devices of the pool, and reformat. Finally, use the Mover to copy all the data back.

If you have absolutely critical data in the pool we strongly recommend making an independent backup first (you are already doing this right?).

This procedure presumes a multi-device btrfs pool containing one or more cache-only or cache-prefer shares.

1. With the array Started, stop any VM's and/or Docker applications that may be accessing the pool you wish to re-partition. Make sure no other external I/O is targeting this pool.

2. For each share on the pool, go to the Share Settings page and make some adjustments:

change from cache-only (or cache-prefer) to cache-yes
assign an array disk or disks via Include mask to receive the data. These disks should be formatted with btrfs and of course, have enough free space to receive the data.

3. Now go back to Main and click the Move button. This will move the data of each share to the target array disk(s).

4. Verify no data is left on the pool, Stop array, click on the pool, and then click the Erase button.

5. Start the array and the pool should appear Unformatted - go ahead and Format the pool (this is what will re-write the partition layout).

6. Go back to the Share Settings page; for each above share:

change from cache-yes to cache-prefer

7. On the Main page click the Move button. This will move the data of each share back to the pool.

8. Finally, go back to the Share Settings page; for each share:

change from cache-prefer back to cache-only if desired

What if I don't care about preserving data in the pool?

In this case, Stop the array, click on the pool, and then click Erase. Start the array and Format the pool - done.

Useful to know: when Linux creates a file system in an SSD device, it will first perform a 'blkdiscard' on the entire partition. Similarly, 'blkdisard' is initiated on partition 1 on a new device added to an existing btrfs pool.

What about Array Devices?

If you have SSD devices in the Unraid array, the only way to safely re-partition those devices is to either remove them from the array or remove parity devices from the array. This is because re-partitioning will invalidate parity. Note also the volume size will be slightly smaller.

Over the years Unraid has grown from a simple Network Attached Storage server OS, to a full application platform featuring Docker containers and Virtual Machine support. It can be daunting for new users to navigate the volume of information spread across our Wiki, Forum and Help section ⍰ within the product itself. With this in mind, we will be publishing a series of new user blog posts over the coming months to address some common questions as well as share some tips, tricks and best practices to ultimately help everyone new to Unraid get the most out of our OS!

The Unraid OS/USB Flash relationship:

A good place to start is with the USB flash drive. We highly recommend you use a high-quality, name-brand USB flash device with at least 1GB capacity. Kingston, PNY, Lexar, and SanDisk brand USBs are good options and will help to ensure that the OS runs properly and the USB doesn’t fail on you. SanDisk Cruzer Fit's are very popular choices for many Unraid users for their low profile design and reliability.

Cheaper ones tend to fail more quickly than a quality USB manufacturer. Once you have Unraid up and running either via a free trial or a purchased license key, it’s important to know that Unraid does not run from the flash drive. The flash drive simply unpacks an archive of the OS into RAM when it boots and the Unraid OS is actually running in RAM. During normal operation the USB Flash device is only periodically written with vital configuration data.
