help chose Shared storage FS

[weerok]

Hello,

Please help to understand one simple implementation solution.

1) Setup
- Storage via FiberChannel,
- multiple servers have FC to shared storage,
- VM will be in qcow format (so we need File System to store them),

2) As I understand FileSystem is required to be clustered version (shared disk FS): just like VMFS (VMWare).
Linux has options GFS /OCFS.

3) Solution like GlusterFS/DRBD are distributed FS (distrubute info from local disks and replicate them) - to complicated, lower performance and use Ethernet (not FC).

4) PVE docs says
/pve-docs/chapter-pvesm.html#chapter_storage
Table 1. Available storage types
Description PVE type Level Shared Snapshots Stable
NFS nfs file yes no yes
GlusterFS glusterfs file yes no yes

NFS - will not use FC and must be provided by Storage OS (which is not the case)

So my question
is there any viable, simple and supported solution for shared disk FS ?

Can you please explain what you're trying to accomplish? I don't understand exactly what you ask. I think you're looking for a redundant storage solution? What hardware do you have for this?

IBM storage is conected with 3 servers via FC, so one shared disk will be available on all servers.
What PVE storage solution can be choosen to accomplish these tasks:
- VM disk will be stored on shared disk (storage),
- Qcow format,
- live migration.
