Wow.
Ok, I don’t have anywhere near that amount of media, but MythTV takes seconds to rescan ~2TB of videos and maybe a minute to get any missing details like fanart, etc.
Similar amount for music - but I feed it the files after I’ve run them through Picard.
I’ve not done a complete rescan of eveything for ages, but from memory it’s like an hour absolute tops. More like ~30 mins.
And that’s on an underclocked CPU (for quietness).
I found the link
“Library scans are expected to take (way) longer in 10.11 because we are now a) properly validating all existing data and b) properly applying concurrency limits. Usually only the first scan after the upgrade takes significantly longer because it will fix some data inconsistencies we can not repair while doing the initial migrations. Any subsequent scan should be faster but if you add a lot of new files it will still take longer than before because of the concurrency limit.”

From the thread for people with more realistic media libraries like yours (5-20tb) the initial scan is more like a few hours. However, if you’re like me and hoard shit expect it to potentially take days
Thanks for this. Good to know! I haven’t taken the leap yet. I’ll plan the upgrade when we will be on vacation…

Fucking hell. OK, I’ll upgrade again and wait longer. Mine’s ~15TB.

Do you have music? I don’t know this for sure but I also wonder if music collections slow things down. My music collection is pretty massive (like 40% of my storage) and it’s a shitload of files to index.
Thankfully I don’t put my books in jellyfin because my ebook/manga library is also pretty massive. If the apocalypse occurs I’m set for the 2-3 days I’d have power after the end of times

I do. It could be this:

Interesting. I will say music is the weakest point of jellyfin db. Mine is currently good but I nuked my db for the new db style in 10.11 and created a new db, mainly bc of issues within music library. But this went back to like 10.9 and were probably from me fucking around in the db manually to try and override tags. I’ve since retagged my music as it was just the easier solution (artist ft artist got me all fucked up, I hated having 900 entries for like 1 artist who did frequent collabs)

This is the issue thread re the very long scanning after upgrading to 10.11
