Slow rescan on Melco N1A

[jacobacci]

I am running fairly large music libraries with MinimServer on
- Synology DS1815+ (11.5TB library)
- Synology DS1019+ (11.5TB library)
- Melco N1A 2EX (two 3TB HDs in RAID0) (4.5TB library)
I am seeing very different rescan times on the NAS' and on the Melco:
Melco: initial scan: 34 min, rescan 32 min
DS1019+: initial scan around 45 min (from memory), rescan around 1 min

Why would the rescan on the Melco take almost the same time as the initial scan, while on the NAS' it is very quick.

P.S. Is there any way I can launch a full initial scan with MinimServer? I would like to redo a clean set of measurements once more.

Set startupScan to 'full', do a rescan, then set startupScan back to 'true' (the default value)

Thanks, Stefano
Your hint allowed me to do systematic testing and look at the logs. I found the cause of the long rescan times on the Melco. jRiver had created a playlist of all the 50k files that I exported to put on the Melco. MinimServer on the Melco could not cope with the entries on that list and spent 35 minutes trying to find the files on the list. I have deleted this playlist.
Now upon restart, the Melco MinimServer rescans in less than a minute.

glad you fixed it

For anyone else reading this thread, MinimServer automatically sets the startupScan property to 'true' after a full rescan has finished. This change was made a couple of years ago so that this setting isn't accidentally left on 'full' permanently, causing very slow rescans.
