Hi Eneko,
thanks for your answer.


I'm aware that the Single Point Of Failure of the shared storage might
be an issue.
But, i' can't afford to spend more money into a second storage server.

About drbd,ceph.
I'm used to zfs, not to ceph. I wouldn't put my main storage system
under an probably-good-but-unknown-to-me FS.

And, isn't drbd limited to 2 nodes ? I found links to use it with 3
nodes, but it sounded very complex, using drbd over drbd over FS...

I may use drbd to replicate FS over 2 nodes inside a 3-nodes Proxmox

According to the vendors, the DAS disk bay is quite indestructible...
I'm too old in IT to trust this guy ;-)


Thanks for non-certified disks, i'll be more confident about that.
entreprise grade SSD from dell or HP are so expensive; nearly 8 times
the price per GB..
May be better , but i can't afford it!
