<pre wrap="" style="white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; white-space: pre-wrap; word-wrap: break-word;">I would be very happy to see mdraid within the Proxmox Bare Metal Installer. The reason behind this is, that I often have Proxmox VE nodes attached to a higb performance SAN or some other shared storage system. Often I don't even use the local storage on a proxmox node, but I'm very happy to see the node still working in case of a hardware/harddisk error. And this is something you can really nice do with a mdraid as local raid performance doesn't matter here.</pre><pre wrap="" style="white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; white-space: pre-wrap; word-wrap: break-word;"><br></pre><pre wrap="" style="white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; white-space: pre-wrap; word-wrap: break-word;">My experiences on mdraid are ambivalent. While a mdraid provides very good stability, raid migration, easy maintenance and good throughput performance, I didn't get a low latency storage (means high IOPS) even on a RAID10 layout. </pre><pre wrap="" style="white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; white-space: pre-wrap; word-wrap: break-word;"><br></pre><pre wrap="" style="white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; white-space: pre-wrap; word-wrap: break-word;">Best regards,</pre><pre wrap="" style="white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; white-space: pre-wrap; word-wrap: break-word;">Marco</pre><pre wrap="" style="white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; white-space: pre-wrap; word-wrap: break-word;"><br>--<br>Kennen Sie schon den inett Newsletter?

I guess we will try to support software RAID when we switch to BTRFS. Doing it at file-system level makes more sense to me. But BTRFS need to be stable before we do that change.<br>> <br>> _______________________________________________<br>> pve-user mailing list<br>> <a href="mailto:pve-user@pve.proxmox.com">pve-user@pve.proxmox.com</a><br>> <a href="http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user" target="_blank">http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user</a><br>> </pre>
