Repair File on RAID 6 Volume - Lemmy.World
I have a RAID 6 volume with data protection on my DS1621+. A video file seems to
have become corrupt - it worked in Plex a few months ago but now it won’t play
at all. I’ve tried in VLC, the built-in DSM video player - nothing seems to
work. No other files appear to be corrupt, all drives show as Healthy. Is it
possible to repair the file, and if so how would I do that? My research seems to
only find results where an entire volume is corrupt. In this case I’d like to
just recover a single file.
Question about Thread - Lemmy.World
Apologies if this is a common question - Lemmy search leaves a little to be
desired still. How exactly does a Thread border router talk to edge devices? Do
they talk directly, device-to-device or will a border router utilize the 2.4GHz
radios in my APs to extend its range?
System Architecture Feedback - Lemmy.world
I’m looking for some feedback on my Plex system architecture. All my media is
stored on a Synology DS 1621+, six 4 TB drives in RAID 6 with one acting as a
hot spare. All four network ports are bonded into a 4G link to an Ubiquiti
USW-48-POE. Previously, I ran Plex in a Docker container on the NAS. This setup
was stable; however, the NAS only has 4 GB of memory shared between Plex,
several other Docker services, and regular DSM overhead. Plus, the processor is
not very powerful (AMD Ryzen V1500B, ~5400 PassMark). A few months ago I
repurposed some old desktop PC parts to build a home lab Proxmox server (Core
i7-6700K [~8900 PassMark], 32 GB memory, GTX 970, an old 2.5” SATA SSD for guest
OS disks, 1G networking on the motherboard). I’m running Plex on an Ubuntu VM,
with the GPU passed through directly to the guest OS. Plex is not containerized
in Ubuntu. The VM has 8 CPU cores and 8 GiB memory (different units in Proxmox).
My Plex media is accessed via a persistent NFS mount in Ubuntu (had been SMB
before a DSM update broke something and the VM could no longer read the
directory contents.) The main purpose of the change from NAS to VM was to
utilize the increased CPU/GPU horsepower and memory that I had lying around, but
I worry that the added layers of complexity (hypervisor/VM, PCIe pass through,
NFS mounts) will introduce more opportunities for performance issues. I have
noticed more frequent hiccups/buffering/transcoding since the change but I’m not
sure if it’s related to my setup or if those issues lie with client devices
and/or the files themselves (e.g. weird file container type that the client
can’t play natively). Any critique or recommendations on system architecture?
Should I get a dedicated NIC to pass through to my VM? Dedicated NVMe drive
passed through as a guest OS disk? Ditch Proxmox altogether and go back to
Synology Docker container?
