Is the Intel 3520 a good option? The 480Gb is available and is priced ok +-300 euro.

"Temporarily out of stock." And it is in the us. I live in europe which would add some taxes and stuff. Is there a current list with ssd which are best to use with zfs?

Ok but I can't find a up 2 date list of "enterprise ssd's" Tried looking for: Samsung SM863 and Intel 3510 but both are no were in stock. Is the Intel 3520 a good option?

Thx for running the tests. Going to test with a 850 Evo 250Gb tomorrow to see if it is 840 related or maybe the IBM1015 IT mode raid card.

Just trying to wrap my head around the fact that the Samsung 840 Pro 512Gb are so slow under proxmox compared to windows. They used to be in a hardware raid 1 on esxi and were blazing fast. Now I run a hdtune test on windows on the 256Gb disk in my pc (which is slower)...

Hi, I am looking for ways to optimize my proxmox / vm / lxc. Currently I have proxmox installed on 2 samsung 840 pro 500Gb in ZFS Mirror. The performance os the ssd are ok (100 Mbps) but not near the normal windows or ext4 levels. Can anyone recommend ssd for proxmox / zfs? For networking I am...

Having the same issue. Any news about when the new kernel will be in stable?

Does ssh to the host works?

Performance is noticeable better getting write speeds of 110Mbps instead of 30. I've just reinstalled proxmox after making backups of the ctx and vm's to another zfs volume. Installed proxmox. imported the zfs volumes. Restored both the interface and storage.cfg rebooted. Restored the vm's and...

Wear level is 18 which is not a lot. Recreating the pool is more difficult because it host my proxmox installation. Anyone has a good solution on how to do this?

I used a shift 12 for 4k but they report as 512 but the internet isn't conclusive about what the best value would be.

I ftp to the lxc container and put the file on the filesystem of the lxc container which resides on the zfs volume.

Did the following: zfs set sync=disabled rpool/vm (Where my lxc containers are) DSK | sdc | busy 100% | | read 32 | write 304 | | KiB/r 256 | KiB/w 128 | | MBr/s 0.8 | MBw/s 3.8 | | avq 2.28 | avio...

Hi, I've installed proxmox on 2 Samsung 850pro 256Gb drives during the setup as zfs mirrors. I've added the ashift value of 12. Both disk smart values report passed. But I've noticed that my windows vm was quite slow. So slow that I converted everything to use linux so I could use containers...

Hi, I have somequestion about LXC: 1. Is it possible to share users over containers. What I mean is this: I got 2 LXC containers A and B. I create a new user USER1 on lxc A. LXC containers both have a mount point to /ZFSTANK/ LXC container A with USER1 put files on the ZFSTANK. How can LXC...

I can confirm that my vm's remain stable with the older kernel.
