I have the following error:
The roll forward start point is now at log sequence number (LSN) 5470633000000066000001. Additional roll forward past LSN 19429240000000043500001 is required to complete the restore sequence.
Now I explain: I have a database in "restoring..." mode, because I applied a restore of files and filegroups, from a .bak file that I took in the past, but I do not have a transaction log file of the type .trn with the LSN 19429240000000043500001, to recover the database. What can I do to bring the database back online or return the restore process without losing the other ndf child data that was in the database?
