Proxmox write really a lot on disk - have look at my graph

[fireon]

Hello,

have here an supemicro server. Last year there was an Gentoo with vdr, webserver... on that local SSD (Samsung EVO). That was running a long time. Little bit wear out.

But after we setuped proxmox on this machine and install an lxc with gentoo and the same services, the wearoutlevel of the ssd goes higher and higher. And that very fast. Have a look at the graph.

I know yes there is an EVO, and yes i merged an Enterprise disk as mirror for secure if the time come that evo fail. But really... what do proxmox that there are a lot of writes? It is absolutely crazy.

HI Fireon,

Yes, I also experienced this with an EVO. If I remember correctly, the PVE fuse filesystem (pmxcfs) and the rrdgraphs are responsible for the heavy I/O. I discussed my experience with the EVO here:
