Then there was something mentioned about namespaces, which should be allocated smaller than the physical drive Is this really needed - just to boot from this SSD? NVMe namespaces are an abstraction layer that allows a controller to present its connected storage as a number of independent volume

Re: [gentoo-user] How to emergency manual install of libffi-compat.

2021-08-20 Thread Andrea Conti
I've bitten by this too... the problem is that portage does not follow a particular order when rebuilding subslot deps, so when upgrading dev-libs/libffi (in this case from 0/7 to 0/8) it can schedule lots of other packages between when the new libffi is installed and when python is rebuilt.

2020-04-13 Thread Andrea Conti
Have your backup cron job call fstrim once everything is safely backed up? Well, yes, but that's beside the point. What I really wanted to stress was that mounting an SSD-backed filesystem with "discard" has effects on the ability to recover deleted data. Normally it's not a problem, but

Hi, CONFIG_PARTITION_ADVANCED=y CONFIG_MSDOS_PARTITION=y CONFIG_EFI_PARTITION=y That's all you need. This could be the key. Sector sizes have been changing from 512 to 4096 over many years. If your kernel has been updated to expect/use 4096 byte sectors, it might not be able to read the disk

Hello, The i219 is a completely different (and much older) chip; the right driver for the i211 is definitely igb. That said, I think the OP should first make sure the onboard LAN is enabled in the BIOS and then post the output of "lspci -tv". andrea On 17/11/20 00:59, Adam Carter wrote: On

Hello, I don't want to use EFI. Then you probably should not be attempting to boot off an NVMe drive, as that is only possible if the drive has an onboard BIOS-mode boot ROM; AFAIK those are only found on some of the earliest NVMe drives. Moreover... grub-install /dev/nvme0n1p2 Installing
