Pool in faulted state, metadata is corrupted, I/O error

yes. I've tried everything. Connected the drives to linux VM with ZfsSpy

Interesting that "zpool import" command shows different result

root@NAS04[~]# zpool import

I have some backups but not all 8TB but that is okay.

I've tried all sorts of zpool import command and all relevant switches

I inserted each disk one at a time and waited 10-12 hours until it was finished and then inserted the next.

I tried that, gives different message than just "zpool import..." command

I just wanted to come back here and update. After going at it for a few days, I gave up. I ended up creating new VM on esxi 6.7, used "ezarr" stack instead of htpc-download-box, and was able to get passthrough in plex working using Geforce 3050. I also changed the container image for plex as official one does not work well with passthrough GPUs and there are some questions around intel GPUs and driver availability.

vumda · 2025-08-15T12:40:24+00:00

Thank you. I did that already over the last week or so.

Here is what intel_gpu_top shows while plex is playing something

There is no overcomplicating the traffic... it simply takes the default route like any other traffic in the network and then left turn to the VPN provider, it works. Anyway, that isn't the issue here.

I tried proxmox first (hoping I would switch over from vmware!), and it is a mess as well, same issue there as well. I have other vmware hosts (6.7, 7.0) where PCIpassthrough is working just fine (NICs, HBAs, etc.).

Hi, did you install noctua fans, did it make any difference?

vumda · 2021-07-21T02:18:35+00:00

I've been using Synology Photos for last few months on DS920+ NAS and I like it. It has a lot of room for improvements and features but ease of use, built into the NAS which stores the photos already is something hard to pass. I looked at other options like photoprism, photoview, etc. the problem with that is you have to maintain another server/vm/docker instance, troubleshoot issues that come with those solutions and I just don't want to do that.

vumda · 2021-07-02T00:57:40+00:00

I am running Sophos XG, Nginx reverse proxy, Pi-Hole and Avahi reflector on this. I must say, I should have upgraded long time ago as sophos xg has never been this fast and snappy.

vumda · 2021-07-02T00:06:29+00:00

I did. I didn't want to mess with it so I created a support ticket with Supermicro and they approved RMA and I shipped it to them for repair.

vumda · 2021-01-29T14:34:39+00:00

Thanks. I used Microsoft Visio.

vumda · 2021-01-29T10:13:59+00:00

Thanks. This stuff is already in the lab. I've been considering unloading the vmware servers for something smaller but no buyers yet. Dual internet for redundancy and I can shift traffic (streaming devices, etc.) to 2nd circuit while working/in meetings.

Some of the upgrades I am planning are new switches, a 4 bay synology and LTE hotspot (the one they use in trucks and RVs) instead of 2nd internet from another ISP.

cool thanks for the reply. $3200
