This was due to SQLite-specific migrations not being filtered out during backup requirement aggregation. This commit adds filtering to exclude migrations marked as RequiresSqlite from backup processing unless the provider is actually SQLite (currently unsupported). This prevents erroneous backup attempts and ensures only relevant migrations and backups are processed. Documentation has been updated to explain the issue and solution. --- .../Migrations/JellyfinMigrationService.cs | 5 + docs/sqlite-migration-filtering-fix.md | 159 ++++++++++++++++++ 2 files changed, 164 insertions(+) create mode 100644 docs/sqlite-migration-filtering-fix.md diff --git a/Jellyfin.Server/Migrations/JellyfinMigrationService.cs b/Jellyfin.Server/Migrations/JellyfinMigrationService.cs index 96718968..c0a070c5 100644 --- a/Jellyfin.Server/Migrations/JellyfinMigrationService.cs +++ b/Jellyfin.Server/Migrations/JellyfinMigrationService.cs @@ -397,8 +397,13 @@ internal class JellyfinMigrationService }; } + // Filter out SQLite-specific migrations when determining backup requirements + // SQLite is no longer supported as a runtime provider + bool isSqliteProvider = false; + backupInstruction = Migrations.SelectMany(e => e) .Where(e => appliedMigrations.All(f => f.MigrationId != e.BuildCodeMigrationId())) + .Where(e => isSqliteProvider || !e.Metadata.RequiresSqlite) // Skip SQLite migrations for non-SQLite providers .Select(e => e.BackupRequirements) .Where(e => e is not null) .Aggregate(backupInstruction, MergeBackupAttributes!); diff --git a/docs/sqlite-migration-filtering-fix.md b/docs/sqlite-migration-filtering-fix.md new file mode 100644 index 00000000..23a53a3d --- /dev/null +++ b/docs/sqlite-migration-filtering-fix.md @@ -0,0 +1,159 @@ +# SQLite Migration Filtering Fix + +## Problem + +When running Jellyfin with PostgreSQL, the startup was failing with an error: + +``` +[ERR] Main: Cannot make a backup of "library.db" at path "/var/lib/jellyfin/data/library.db" +because file could not be found at "/var/lib/jellyfin/data" +``` + +This occurred even though: +1.
