Sure, but it is somewhat impractical with a 6 TB fileserver image and 
500 users screaming for their files ;)

And I fully expect to be the reconstruction much easier than Ceph but, 
from what I read, Ceph is less likely to broke in the first place. But I 
admit I never seriously run a Ceph cluster, so maybe it is more fragile 
than I expect.

 From this very list I read about many users with various problems when 
using NFS Ganesha. Is that a wrong impression?

Sure - the command itself is simple enough. The point it that each 
reconstruction is quite more "riskier" than a simple RAID 
reconstruction. Do you run a full Gluster SDS, skipping RAID? How do you 
found this setup?

Thanks.
