Greetings from 2024 with a DS1819+ running
DSM 7.2.1-69057 Update 3.Had some corrupted leaves and managed to get
btrfs check /dev/mapper/cachedev_0running by unmounting viasynostgvolume --unmount -p /volume1as mentioned in this xpenology thread and above. It did not shut down SSH for me.Additionally, I couldn't run
btrfson/dev/vg1000/lvor/dev/md2, only/dev/mapper/cachedev_0worked properly for unknown reasons. Good luck to you all.
