Re: [xmail] Mailbox on NAS
This is a know 'move' issue with mounts to/from logical high level networking file systems The reason why this works for ramdisk mounts is because the ramdisk is a local low io dev to the system You could try to mount from an iSCSI drive (if your nas/san support it) as the target is considered as a local harddisk ressource even if finally hosted on a different system And Iscsi is very 'performent' compared to 'high level' network file systems like nfs, ...

Re: [xmail] Mailbox on NAS
You probably have root squash turned on. Meaning no root access over nfs. Ps. NFS is really not a good way to fix your low storage needs. Email systems has too high a reads and writes count NFS to stay stable very lonh with out a at least a nfs restart twice a day. And durning that time you'll need to stop xmail and restart it only after you confirm NFS and its mouts come backup clean. Oh and ever forget to write your self a stale mount checker. As when NFS go stale you'll need to stop incoming mail and fix the mounts and restart mail. On Sep 8, 2011 7:28 AM, Rittikorn L rittik...@ttni.co.th wrote: Update.
