[sheepdog-users] Some question from new user

[Raymond Burkholder]

> 1) is sheepdog stable and ready for production use?
I am just finishing a prototype on a set of three servers.  Can't answer
this yet

> 2) do I need any metadata servers (like Ceph) or the only needed servers
are
> the storage ones (like Gluster) ?
No metadata servers needed.

> 3) can I use multiple disks in a server, or each server should "expose" a
single
> filesystem (thus, I have to use RAID)
In my prototype, I use two physical drives, stripe them together with ZFS,
and export the pool to sheepdog

> 4) is RAID suggested ? I prefere to use some JBOD
The above combo gives some local speed with jbod, and sheepdog takes care of
the redundancy

> 5) is possible to expose a POSIX filesystem stored on sheepdog?
Does sheepfs do that, havn't looked into it yet.

> 6) how to use S3 API ?
Don't know


> 7) any "scrub" feature to be sure that all object a replicated properly
and not
> subject to "bit-rot" ?
I have the same mind set about bitrot, and sheepdog doesn't deal with that,
which is why I used zfs to handle that with striping.  I could have used
btrfs.

I am finalizing routing in the next few days, and then can see if this whole
thing works as expected.
