Even a refurbished dc ssd will propably last longer than a consumer device of your boss won't veto it.

...more than the 2Gb/1Tb rule mentionned by @fabian somewhere on another discussion in this forum. I don't want to use consumer grade ssd, i have to. The only ssd datacenter disks i already have seen on sale here are refurbished ones. The others brand new ones i have seen come as part of an...

You probably know the answer, technically yes. But no one will recommend that... If you need to use consumer grade SSDs: 1) use different brands. 2) use "too large ones" intentionally. 3) run a mirror vdev consisting of three devices instead of just two. 4) make backups to physically separate...

if your ssd's dont have power loss protection then the performance with zfs will be worse because writes cant be cached for data safety Samsung 870 SSDs are consumer grade and dont have PLP so zfs with these ssd's is not really recommended, the tbw rating is low and with zfs write amplification...

Hello community Sorry for newbie post like this as I will probably get recomendation no to go that way. But I am still curious about cause of this issue First of all, its home lab, single node Proxmox cluster. My son bought second-hand Dell PowerEdge R730xd. Server has PERC H730P Mini Embeded...

what is the point ? install PVE on HDD because no speed is required for PVE itself, rpool will be the slow zpool. second zpool for whole ssd. balancing data between the two disks will be done with moving vDisks between the two Storages. (don't forget ZFS eat / quickly wearout consumer grade SSD...)

Statistically, the disk will fail first. SSD fail hard and are - at least in my experience - not recoverable. It's just ewaste that does not get recognized at all. If you can live with data loss, you can use only one. ZFS is the only filesystem that does currently incremental replication, so you...

Sure. As long as you replicate all VMs then you're right. I must admit that I do not always do this, because sometimes it is "just a Test-VM", or be it because of the pure size of a VM I explicitely do not want to replicate. I want all nodes to work reliably. With mirrors in my ZFS pools the...

@UdoB and @LnxBil thanks! Please help me think this through: Since I had a relatively cheap way to get a whole 2nd box, I was thinking I don't need to get redundant storage in each of them. I realize that duplicating the whole node (and running cheaper consumer drives) means increasing the...

background: I am working towards migrating approx 12 clients from ESXi (the straight-up free version) to proxmox. I have been using ESXi, and ghettoVCB, to read and write to NFS, hosted on ZFS provided by FreeBSD, for close to 20 years (along with all the other stuff you can do with zfs). So I...

...eine Dc600 eh ist) da durch die Logs und den HA Service die Disk konstant mit kleinen Daten beschrieben wird( was tötlich für eine Consumer grade ssd ist). Also how you like it. Du kannst auch Proxmox auf die ZFS Platten installieren zu den VMs und die HDD rein für Backups (kein Problem in...

...back as OSD to Ceph Deactivated NOCD for the SSD's in grub GRUB_CMDLINE_LINUX_DEFAULT="quiet libata.force=noncq" I know that the consumer grade SSDs or not ideal für server use, but these 4 servers have a very low load and there are not that many iops. We just have 10 VMs on 4 Servers... So...

You can try to look at earlier logs in the journal to see if it reports any other issues. Until then, I will try to concentrate on the Ceph issues, as these are the ones that cause issues at the moment. My guess is that all your issues are related to storage, but please check earlier logs to see...

Some strategic decisions are "common sense". The classic approach is to separate OS/PVE from VMs virtual disks from user data. This is still recommended, but most Mini-PC in a Home-lab environment just don't have enough Sata-Ports or M.2 slots for this, and so it is often tolerated to just use...

870EVO are the very bottom of consumer grade, even desktops won’t run well on it. That being said, what do you expect, what is your networking setup etc. You’re also just doing 1 FIO test, Ceph has its own performance testing and there are lots of tweaks and knobs on FIO, what is your workload...

I use 4 Dell R740 8 SSD disk slot servers to deploy Proxmox in the lab. 2 of the disk slots use RAID1 for installing the system, and the other 6 disk slots use Samsung 870EVO as CEPH storage. But after deployment, CEPH's performance is very poor. I used fio to test it, and the iops was very low...

Hi there, i run proxmox on an old laptop. As storage i use a consumer grade 1TB Crucial MX500 SATA SSD. Now i have a free spare 960GB Sam PM863 from my workstation, which i put in the optical bay as 2nd drive. The MX500 SMART vaules still look very good, but i'm thinking about making the...

Hi, Just to confirm, this was the issue, everything works great and even write speeds are better. Guess that for some reason I haven't noticed this before moving Proxmox installation to HDD, but clearly that was not the issue, using cache on consumer grade SSD was. Thanks once again Gabriel.

Hello, Since it's new year i want to expand my homelab, currently RPI4. Not so long ago i bought 3x HP Elitedesk 800 g6 mini (i5 10500, 8GB RAM and 256GB SSD in each). I checked if they work and since then they've been collecting dust. I want to build small proxmox cluster and i cannot decide...

I don't have a price feeling for $, only for € ;) If they last. You could buy a mix and dump your backups (this is writing in bursts) to a cheaper one and see how it goes. VMs, on the other hand, produce continuous write operations and I would always choose enterprise class. It is also...
