Bisq doesn't operate on remote NAS devices over SMBFS

[gregturn]

Description

Bisq works great on my local Mac. But when I move my wallet to a remote RAID-based NAS (over SMBFS), it can't launch properly and thus fails to get started.

Version

1.7.4

Steps to reproduce

1. Install latest version of Bisq.
2. Set up an alternative location for the wallet.

$ mount 

//zzz@remote-nas-storage-unit._smb._tcp.local/Bisq on /Volumes/Bisq (smbfs, nodev, nosuid, quarantine, mounted by zzz)

3. Launch Bisq but with an alternative command.

/Volumes/Bisq/Bisq.app/Contents/MacOS/Bisq --appDataDir=/Volumes/Bisq/BisqData

Expected behaviour

I expected Bisq to come up just fine. In fact, it does if I let Bisq use the default path of ~/Library/Application Support/Bisq.

Actual behaviour

Bisq fails to launch. It complains about a potentially corrupted SPV file. But in truth, it appears to need to do some form of low level locking on the SPV file, which for some reason, the NAS in it's configuration is unable to do.

And so it throws this stack trace:

Device or machine

I'm doing this on MacOS Big Sur. The NAS runs ext4, which is standard Linux. But the partition is smbfs, nodev, nosuid, quarantine.

Additional info

I need this because running Bisq (Tor-based tech) directly on my machine violates security policy. By running everything off of my NAS, I can continue using Bisq. Hopefully, there is some easy adjustment to the code that may make it operational.

Thanks for opening your first issue here!

Be sure to follow the issue template. Your issue will be reviewed by a maintainer and labeled for further action.

Perhaps using a symlink pointing to your NAS but keeping the symlink in the default path.

Something like ln -s ~/Library/Application Support/Bisq /Volumes/Bisq/BisqData
