What do you have in your bitcoin.conf file or command line parameters?
Because AFAIK, Bitcoin Core wont work if you set its datadir to a NAS due to leveldb incompatibility.
I don't know how you managed to make it work before but try to set only the "
blocksdir" to your NAS and leave the "
datadir" to your local disk.
There surely must be some other detail(s) some of you could find for me to not expect the bitcoin core software to work and give up on the question I asked?
Feels like you already expecting an answer and just want to make sure...
