March 29, 20251 yr Hello, I am new to Unraid and just put together my first system recently mostly following the NAS Killer 6.0 guide on the Server Build Forums. Currently I just have pictures, videos, music, and some documents stored and am running a Plex and a bedrock Minecraft Docker. I have the attached disk layout and would like to move all app data from the cache NVME to a recently installed SATA SSD. One reason is I was told the metadata performance will be much better with Plex, which currently I do notice some things slow to load initially in Plex. What is the best way to do this? I assume from a high level it's copying the data to the new drive and changing some configuration to point things at the new location, as well as telling it to default there for new appdata. Let me know if there is any further information I can provide. I appreciate any guidance and insight provided.

March 30, 20251 yr Community Expert You can use the mover, make sure the docker service is disabled first, then adjust the appdata share: https://docs.unraid.net/unraid-os/release-notes/6.12.0/#share-storage-conceptual-change
March 30, 20251 yr Community Expert Solution Also https://docs.unraid.net/unraid-os/release-notes/7.0.0/#share-secondary-storage-may-be-assigned-to-a-pool So you can move directly from one pool to another.
March 30, 20251 yr Author I believe I was able to accomplish what I was looking to do with the assistance provided. Thank you so much for pointing me in the right direction.

March 31, 20251 yr Community Expert Something we haven't discussed in the thread, Minimum Free (for pools and for shares). None of your pools have Minimum Free set. https://docs.unraid.net/unraid-os/manual/storage-management/#minimum-free-space-for-a-pool Maybe not relevant since none of your user shares are configured to overflow anyway (Secondary storage), so be careful you don't fill them up or they might corrupt. Each user share also has its own Minimum Free setting. https://docs.unraid.net/unraid-os/manual/shares/user-shares/#minimum-free-space Looks like some of yours have calculated defaults, which you might want to edit. appdata is all on applicationdata and configured to only write new files to applicationdata. Looks like its Minimum is currently about 195G, which means if that pool has less than that free it won't allow any more writes for that share (and no place else for more writes to go). Probably you want that lower. DVR share has some files on dvr and some still on cache. It is configured to only write new files to dvr, and those on cache won't be moved since the share has no Mover action. No Minimum set for that one, so it could fill up dvr completely before it fails to write another file, and btrfs seems to corrupt if it gets too full. system share is all on cache and configured to only write new files to cache. No Minimum set for that one, but unlikely to fill anything with system share since it typically only has docker.img (20G) and libvirt.img (1G). If you ever think you need to make docker.img very large, ask for advice since it probably means you have done something wrong. All other shares have all files on the array, and configured to only write new files to the array. I didn't check Minimum Free for each, but you should consider what those should be.
March 31, 20251 yr Author I appreciate the additional insight, I will look at all these settings this week and update once done.
