The "generally don't see any bugs/issues" is the part I'm worried about (generally isn't comforting).
I was covering my **** on that one. Sods law dictates as soon as I say 'never' we'll discover an issue.
If you use a more traditional filesystem like ext2/ext3/ufs/etc then yes. But you can use a cluster filesystem to get around this, and run
active-active.
I've spent a week looking at the likes of PVFS, GFS, Lustre and a whole host of different systems, including pNFS (NFS 4.1)
At the risk of diverting the thread away from the SATA backend, is there any recommendation for a fault tolerant file service.
I'm really looking for 3 or 4 boxes to store data/metadata to support 10 Apache and Dovecot servers.
The things I don't like are having a single metadata server be a single point of failure.
