I use the hardware raid for mirrored boot drive only, and NFS over 10G for VM storage, which is on a seperate system running FreeBSD + ZFS. But for your case: the general rule for any storage system is don't mix. You pick one and only one: hardware raid, software raid, zfs, ceph, etc. The exceptions are for systems you almost definitely won't be using like luster and gluster. You can still do hotplug with JBOD mode, at least on the dell hardware I've used. I have no idea if it's officially supported or not. I do know that I sometimes have to use the raid tools to bring in a new drive when it's NOT in JBOD mode. In the 6ish years I've run ZFS I've only had one drive fail (pure luck, not skill), and it was trivial to swap out and replace. --Kyle On Mon, Apr 19, 2021 at 7:59 AM Leandro Roggerone <leandro@tecnetmza.com.ar> wrote: > > Hi guys , I received a very old del pe 2950 box. > Fortunately it has 64 GB and a double power supply, so i'm thinking about > using it with pve. > After confirm with dell support about storage capacity: > Max physical storage support is 2TB. > Max virtual storage support is also 2TB. > ## > I was reading on previous emails at this mail list , about storage: > "putting the controller in JBOD mode > and install directly with ZFS software RAID." > > I always thought that raid hardware controller was the best option but , > perhaps I can give it a try to ZFS software RAID with this old server .... > what do you think ? > I have a bunch of 3.5" with odd capacities unused drives. > I readed that zfs can merge them to get a more efficient use. > What about hot replace / remove or insert a new drive ? > Will it work without service disruption in production environments ? > > Regards, > Leandro. > > <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> > Libre > de virus. www.avast.com > <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> > <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> > _______________________________________________ > pve-user mailing list > pve-user@lists.proxmox.com > https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user >
