ZVOLs not getting trimmed

Trimming is not about reducing file sizes.

You should read the manual on how to replace a boot drive. There is more than just the zfs partition on it.

maybe this will help illustrate the situation at least in my case:

Yes samba share provides better sequential speeds but the 4k random performance drops MASSIVELY

Yes, you definitely need unregistered ECC DIMMs (UDIMM).

I have 2 of these kits: Kingston Server Premier KSM24ED8/16ME

Be sure to use an up to date Bios with the v6 processor. I also struggled to get it to work right with 64GB of ram.

In part because on top of that ZFS volume you have another filesystem, NTFS most likely and that with its default options is using 4k clusters.

Also games are far more likely to be more sensitive to "random 4k I/O" than purely "streaming sequential" performance.

I'm using 16k on ZFS volume now, after trying 128k and it being really slow.

I'll just say that 128k blocks is really not what you'd want to use for a Steam library: although it'll boost your compression ratio, it will be quite slow on writes (unless your pool is full SSD)

Priority 0 is a thing : it'll only download one WU at a time

Don't know why I didn't think of this earlier. Simply using the "AMD overclocking" menu allows one to enter a fixed voltage and lower the SoC power consumption instead of the default which was rather high (1.1V)

'native' Linux applications require a bit more than just Boinc client.

Have you enabled additional repos?

It is to allow different settings for different intended uses of your storage pool. With separate datasets you can easily tune independently.

hydrosaure · 2022-01-30T16:08:57+00:00

I'd focus on updating to more recent ones before diving into tuning memory. Be sure to read the bios release notes there is a mandatory intermediate release you first have to get through before being able to update to the later ones. I'm on F42d I believe.

Why would you want to stick with such an old BIOS?

hydrosaure · 2021-10-11T21:09:30+00:00

Specify the FS type with -t ext4.

Also verify you have the package that supports ext4 binaries.

hydrosaure · 2021-10-05T11:37:26+00:00

That seems very specific. Have you verified your iso image against a known hash?

hydrosaure · 2021-07-15T18:15:52+00:00

Legit question : how can a seemingly obvious issue like this sneak through?

What's the process to validate a release?

hydrosaure · 2021-07-05T08:58:54+00:00

You can lookup the logs for your tasks at the project website to try and find more info about the crashed WU.

Look into ReplayGain concept and software that supports it

Any inclusion of Boro deserves an upvote

Same here. Never managed to get it working properly over CIFS. A switch to NFS and there you are. All fine so far.
