OK, thanks for your answer.
In fact, i had a look in ceph since your previous mail.( February, 5th).
And Ceph seems really interesting indeed!
No SPOF, no need for external SAN,.... i'm currently working on the
change in configuration. (In fact, i'm waiting for my reseller sending
me proxmox-subscription license&tickets).

Filling the 3 servers with 1 SSD (for journal) and (at least) 4 disks.
Pretty elegant solution, no SPOF, but ...no experience on ceph (on the
opposite, i'm used to ZFS..which is not a clustered FS..).

To be continued.
Thanks.
best regards
