free Starwind x Proxmox SAN storage plugin

[itsnota2ma]

@mihsu81 Thanks for the help! The PegaProx helped a lot. I did notice it is missing the import tool. Maybe there is a plugin??

Anyone have any technical info on the starwind storage plug in? I looked at it on their website and forum, but just high level marketing info, no real technical details on how it works. I use 3PAR FC storage with all my proxmox clusters, and needless to say, if there is a way to enable VM level snapshots on LVM storage, its a huge win.

Hi,

the plugin uses a LVM thin Pool per VM disk(s) with an initial Pool size which gets autoextended (activation/thin_pool_autoextend_threshold & thin_pool_autoextend_percent) via dmeventd and it ensures also proper cluster locking

similiar like discussed here in P.S.:

Hi, I have also looked at this.
I'll try it soon, and compare vs gfs2 && ocfs2.

The only diff vs ovirt, is that proxmox use internal snapshot, I don't known it's playing fine with qcow2 on blockdevice. (That's also mean than we can't shrink blockdevice after delete of the snapshot)

Hi spirit,

your qcow2 over LVM implementation looks promising - esp. the qmeventd daemon way sounds like a smooth solution - I think this is the missing piece for an all-in-one >host based< shared block storage / SAN solution with similiar...

only 2 concerns on my side:
- who is officially supporting this plugin (Starwind ?) for production environments
- making/monitoring extensions of ev. hundreds of VM disks/(thin pools) dependent on one daemon -> maybe also risky ... at least it must be add. monitored .. also ev. VG "exhaustion" ..... in a write heavy environment

I hope proxmox will add a plugin like this from starwind into it baseinstall. With a supported plugin like this it will be easier for migrating from vmware to proxmox
