Friendly reminder that, apparently from what I read from e.g. ServeTheHome and Backblaze, there is non-trivial likelihood of mechanical drive failure upon re-silvering (it goes up to 7% average risk on typical WD/Seagate/Toshiba/etc drives). That's why Raid 6 / Z2 is effectively recommended for mechanical arrays - because 1 down has a 7% chance to become 2 down upon re-silvering, which would thus fail at that point in Raid 5/Z1. I'm telling you this because it's important to keep as many spares as your parity number on-site (so Z1 = keep 1 spare, Z2 = keep 2 spares, etc.) Also consider hot-plugging those as "spare" declared as such in ZFS, which will automatically re-silver upon failure). Because when your Z2 is essentially degraded to Z1 upon failure of 1 drive, you really want to have that second drive handy ASAP if you're going to need it. Statistics again say that you'll need that second drive 7% of the time after a first failure. You'll lose any parity on the Z2 array when that happens - so not only should the resilvering happen ASAP at that point, make sure you have a backup ready just in case!
@AmmarossPlays3 жыл бұрын
Let me clarify a bit. You have a high likelihood of having additional errors during rebuild. Traditional hardware RAIDs will eject drives for minor errors like retries/bad bits/etc, but ZFS is more resilient and will be able to gracefully correct bad block data with checksums and/or parity data. So, even with raidz1, if you're rebuilding a lost drive and you hit a URE or bad bit, it can still recover, or at the very least have a single file corruption rather than losing the array. STH/Backblaze data were likely based on traditional hardware RAID. That said, RAID5 might as well not exist when you're talking RAID with disks larger than 2-3TB, especially with the 8TB we're using in the vid. Just the statistical likelihood of hitting a URE is nearly guaranteed at 6TB.

Much prefer unRAID for a home media server solution! unRAID has the advantage of being power efficient by not requiring all drives spinning (only the drives required are spun-up). Also, continuously upgradable with larger individual drives, but still dual drive failure secure. And you can still include Plex server onboard, via Docker. I’ve been running my now 16 drive unRAID server for many years, only adding larger drives as more space is actually needed. So unRAID also allows budget optimisation by enabling you to only buy the current optimal per TB cost drive size, to add, as and when you actually need to add capacity. So your media server can just continue to grow in capacity as needed over the years, with the smallest older drive eventually swapped out for latest larger drive, as they near end of life or more capacity is needed. Nice! :-)
@AmmarossPlays3 жыл бұрын
We set the "autoexpand" option for just that reason: as time goes by and you upgrade the size of your drives, it will autoexpand up to the size of the smallest drive in the array. You are correct you can add additional drives as your chassis allows, which is a great feature of unRAID. Since ZFS is a software RAID, it technically can allow all the disks to spin down when idle too. At least the unRAID license is fairly cheap, so cost isn't a huge factor.

If it watches the by-id path you gave it, then a replacement would never appear in the same area; if it is just looking at physical connections, what happens if two drive bays get swapped, will ZFS think this is a twin drive replacement and start resilvering the two "spares" into each other? Any edge cases where the boot drive might start looking like a "spare"?

ZFS auto-replaces the drive by knowing the sdX that went missing and detects when a new device is plugged in to the same sdX. Basically, you pull the old drive from the hotswap and plug in the new drive and ZFS knows it's to replace the old one.

To answer the "drives swapped" question, ZFS can identify the drives properly, even if you pulled all the drives out, scrambled them up, and plugged them back in (obviously don't do this while it's online!).

@@AmmarossPlays OK, we haven't had serious problems but annoying ones. For instance: Rhel was unable to mount the zfs pool after a reboot automaticly. Problem was the system was configured to share the pool via iser. Iser could not find the mount point so the service did not come up with it... Hilarious crap. That bug is known for multiple years and the bug report has bee closed by RedHat as there is a workaround where you have to manually create some sort of cache file to tell the system that there have been a pool and it should mount it... Ubuntu was running okish with openzfs but kept sharing data via iscsi instead of iser (had to manually restart the iscsi server to load the correct configuration..) that was the only distro we had running semi productive.. Seriously..... This is just bad. Oh and in one instance - we were benchmarking different os/pool layouts the rehl distro crashed randomly. And somehow managed to corrupt the whole pool... It was a complete write off... Freebsd in the other hand. You boot it, configure it. It works.

I know ya favor AMD generally over here, but this is one of the few dumb use cases for it. Or one of the few good use cases for an Intel CPU with their iGPU depending on how you want to look at it. Really weird to go AMD for Plex.

Agreed, I'd definitely take an Intel CPU with quick sync for a media server. Those things are beasts for transcoding.

You should have updated the BIOS first. See kzbin.info/www/bejne/Z6uWaKGCosyFfrs V1.70 was 2 month available when this was published. Because of this the XMP profile most likely doesn't work.

CPUs have the dots, but the 3000-series APUs still used the triangle.

The rule of thumb for ZFS is 1 GB of RAM per TB of actual disk. So does this server have 12x8TB, so about 96GiB of RAM ? EDIT: 14:51 shows 16 GiB of RAM, I guess with an absolute nightmare situation you could transfer the disks to a different system which has the needed 96GiB of RAM and rebuild there. Or possibly the future price of RAM (when a major failure does occur) will have dropped that you could, if the motherboard and firmware supports it, put 24 GiB modules into each of the four memory slots.

Your "rule of thumb" is for enabling deduplication, not for our use-case.
@itsevilbert3 жыл бұрын
@@AmmarossPlays For deduplication the rule of thumb is "5GB of RAM for every 1TB of disk". The real problem with low RAM is when the pool is nearly full, yes it can re-silver with much less RAM, but it will require much more disk access and the one time you really do want to minimise disk access is during a major re-silver. Try filling your disks 90% full (which would never happen in real life, because finance would never delay a Purchase Order for two quarters), remove one disk to simulate a disk failure, and see how long it takes to re-silver.
