![]() There are many ways to manage Docker images and containers too, so installationĪnd maintenance of them will depend on the route you choose.ĭoesn't specify any default volumes, besides To install and use these Docker images, you'll need to keep the above in mind while following their documentation. Keep in mind that Radarr will need read and write to the download folders as well as the final folders.įor a more detailed explanation of these issues, see The recommendation is to use a common group for all related containers so that each container can use the shared group permissions to read and write files on the mounted volumes. The default user, group and umask, you should decide this before setting up all of your containers. Most images have environment variables that can be used to override Permissions and ownership of files is one of the most common problems for Radarr users, both inside and outside Docker. If this advice is not followed, you may have to configure a Remote Path Mapping in the Radarr web UI (Settings › Download Clients). The best solution is to use a single, common volume Some also recommend paths for the download client container that are different from the Radarr container, like ![]() This causes slow moves and doesn't allow hard links because theyĪre considered two different file systems ![]() Both problems can be solved with well planned, consistent paths. The second is a performance issue and causes problems for seeding torrents. torrents/My.Movie.2018/, but in the Radarr container that might be at The first is a problem because the download client will report a download's path as ![]() There are two common problems with Docker volumes: Paths that differ between the Radarr and download client container and paths that prevent fast moves and hard links. Radarr v4 will convert the given directory on startup if a Radarr v0.2 or v3 database is found. Click on the Action button and select Change RAID Type from the list.Volume to mount the data directory and supply that path to Radarr as parameter. To change the RAID level, open the menu – Storage Manager – Storage pool. Also, all the disks should be of the same type. When adding disks to the array, their capacity should be more than the capacity of the smallest disk in this pool, or equal to that capacity. The minimal disk number for RAID 5 is three, and you need to add at least one more disk if you want to convert it into RAID 6.īefore changing the RAID type, make sure that your storage pool is healthy. To be able to change RAID type, the NAS should have a sufficient number of hard disks installed in it. For example, you can create a RAID 1 storage pool, then change it to RAID 5 as soon as more hard disks added, and then transform it into RAID 6 at a later time. With NAS devices, you can change RAID types for storage pools without worrying about possible data loss. Also, when you open DiskStation Manager, you will see a warning that one of the pools has a degraded status, and that it’s recommended to replace the failing disk.Īs long as we have described the process of adding a hard disk, let’s also explore how to add more hard disks to a NAS storage device and migrate the whole system from one RAID level to another without losing data – for example, from RAID 5 to RAID 6. When a hard disk is out of order, NAS gives out a loud beep as a signal. That is why it is recommended to replace the faulty disk as soon as possible. If one more hard disk breaks down, repairing the RAID and recovering data will become even more complicated (and sometimes next to impossible). So, it’s only a matter of time before other disks start suffering from errors. ![]() What is more, the remaining disks within the array are now experiencing more workload, because they have to do the work that used to be done by that faulty disk. However, your array has just lost its fault tolerance feature, since the RAID is going to crash as soon as one more disk breaks down. This particular technology lets your NAS work as usual even if one hard disk is damaged, so you don’t need to hurry and replace it with whatever disk you have at hand. If your system uses RAID 5 technology to store data across an array of hard disks, and only one disk is down, things are not so bad. We’ll be checking it with a Synology device and a RAID 5 system for illustration. How to Recover a Degraded RAID 5 Synology NAS, and Change from RAID 5 to RAID 6 Without Losing DATAīefore you replace the faulty disk, you need to identify the RAID type and understand if it supports replacement of disks without data loss, and find out how many hard disks can be down without interrupting the operation of this array. ![]()
