I am still trying to find the origin of my NAS scanning issue (which I am almost done I think). In this process of scanning numerous times to add every artist that works without restarting the Mpd deamon I loose lot of time with the .iso file scan errors as follow :
from Journalctl -f :
Mar 13 20:34:29 volumio mpd: iso9660: Failed to open ISO9660 file /var/lib/mpd/music/NAS/H-P/Herbie Hancock/SACDISO Head Hunters/HERBIE HANCOCK - HEAD HUNTERS.iso
I know this is not the real issue as it comes from something else I haven’t identified yet which is related to this message from journalctl -f:
Mar 13 20:31:14 volumio kernel: Unhandled fault: alignment fault (0x92000021) at 0x00000000eeb0939f

… mpd restart erasing the database from the actual running database scan but not the entire collection if previous scans other drives have been successfull.
