[Samba] Writing to shares directly

[fixed]

Thank you for your reply.

We are using Samba to create a redundant file system for failover between
two servers. I am wondering if this is even a recommended use for Samba.

For example:

app01
------
/data/shares/app01 (local)
/data/shares/app02 (remote)

app02
-----
/data/shares/app01 (remote)
/data/shares/app02 (local)

So we have written our apps to write to both shares - if one goes down,
this isn't a bad thing as it will read from the local share.

Thank you
