The efforts are far less than reconstructing the disk of a VM from CEPH. In gluster , just run a find on the brick searching for the name of the VM disk and you will find the VM_IMAGE.xyz (where xyz is just a number) and then concatenate the list into a single file.
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.
That's true, but you could also use NFS Ganesha, which is more performant than FUSE and also as reliable as it.
From this very list I read about many users with various problems when using NFS Ganesha. Is that a wrong impression?
It's not so hard to do it - just use either 'reset-brick' or 'replace-brick' .
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?
