I tried doing something similar to this using Sharity instead of Samba (SMBclient is not available in Solaris), i.e., mounting a shared Windows 2000 folder via NFS on a Solaris box. The mount part worked fine, but Cyrus wouldn't write to the Windows NTFS file system. Logged messages like "Invalid mailbox type". Apparently Cyrus need unix semantics, mmap, etc.
I do have two sendmail/cyrus boxes delivering mail to one Solaris mail store shared via NFS to the two sendmail/cyrus boxes. I have read that Cyrus over NFS can be unreliable, but it's working on a small scale in the lab. The db stuff has to remain local to each sendmail/cyrus box, and you are right, they do get out of sync with each other, specifically the *.seen and *.sub files. If anyone has ideas for mirroring the two please share. Our next step is to try putting a SAN behind the Solaris mail store via iSCSI and serve a SAN file system via NFS to the two sendmail/cyrus boxes. I fear we'll have file system type issues again with this, but I'll let you know.
