The issue is that in the bios I see two entries, the entry that is listed as "Samsung SSD 970 EVO Plus 250 GB (238476 MB)" is sometimes automatically selected to boot, the boot process halts with a one line "No active partition error. Then I have to get into bios to choose the line that says "line No 1: UEFI OS (samsung SSD EVO 970 Plus 250 GB)" This is why I raised the 30 blocks / GB-MB issue. > > Then there's a little extra used for filesystem structures. > > > > It started with the warning: Not all of the space available to > > /dev/nvme0n1 appears to be used, you can fix the GPT to use all the > > space (an extra 30 blocks) or > > continue with the current setting? > > 30 blocks is nothing.

It maybe possible that disk IO is saturated.

sometimes graphics is slow, with high Xorg CPU usage
Hi all, For some time now, my -CURRENT system will occasionally get into a state where graphics is slow to refresh and the Xorg uses ~50% of CPU. I notice this in Firefox or GVim when repeatedly pressing PgDn on a long site/file, and in Evolution (emails are slow to load, and text input is laggy when composing a message). Rebooting often fixes it temporarily. I suspect that it happens after suspending, but I'm not entirely sure of that. Any idea what is going on, or how I can fix it? Below is the dmesg and Xorg logs.

The more cycles you waste, the faster your battery starts degrading. Gee, I thought this was misc@, not pleasexplainhowbatterieswork@.

Depending on where the error is, you might get away with dd'ing with conv=noerror,sync, changing vm.conf to point to the new copy, and run fsck in the vm. And buy a new hard disk or SDD. Probably cheaper than your time to further diagnose it?

vmm/vmd disk issue
Hello! A few times I have had problems with my guests freezing (no console, no ssh) when reading a specific file and only a complete reinstall seems to solve the problem. This has happended with both raw and qcow2 disks and on both 6.7 and 6.8. I'm only using OpenBSD for the host and guests. When the freeze happens the host logs these messages six times vmd[24266]: vioblk read error: Input/output error vmd[24266]: vioblk: block read error, sector 23122496 I also found this a few days back that may be relevant vmd[39543]: vioblk write error: Input/output error vmd[39543]: wr vioblk: disk write error If I try to cp or dd the disk image on the host it fails dd if=disk.raw.old of=disk.raw.bak bs=1m dd: disk.raw.old: Input/output error 8858+0 records in 8858+0 records out 9288286208 bytes transferred in 102.048 secs (91018010 bytes/sec) The host show no other signs of failing hardware. Is this a software or a hardware error? Is there some way to recover the guest disk image without a complete reinstall? Thank you in advance, Jan J

I am writing from a T-495. although i have no direct openbsd technical advice for you, i thought i would ask about your reason for TLP ? often by understanding your requirements, the community may be able to offer alternate solutions. perhaps as your name suguests you may be located in the Indian sub continent, and Mains Power may be intermittent.. and your looking to get through a days work.. or perhaps you want to maximise your Mobile work sitting in a park ? or perhaps you jsut really like 80% battery :) it's my personal finding that TLP on linux since kernel 5.x does very little.. i am using right now Pop_OS! (because of citrix/MS-teams for work), and i get about 5-7 hours run time.. with OpenBSD i get about 5-6. (no citrix/MS-teams) MS-Windows-10 to my chagrin, outperforms both bsd/linux reaching closer to 10hrs. so if battery runs times are important to you, you might have the wrong mix :( -Sub. - > > Ottavio Caruso > > A: Because it messes up the order in which people normally read text. > Q: Why is top-posting such a bad thing? > A: Top-posting. > Q: What is the most annoying thing in e-mail?
