Re: GNOME mounts a disk that is not included in fstab

not quite sure about the output of the strace command.

openat(AT_FDCWD, "/sys/dev/block/../../devices/pci0000:00/0000:00:02.2/0000:11:00.0/nvme/nvme0/nvme0n1/removable", O_RDONLY) = 3

thanks for the shortcut with tail.

Re: GNOME mounts a disk that is not included in fstab

It's the files lsblk actually checks for the hotplug result.

Re: GNOME mounts a disk that is not included in fstab

soo, this would be a lsblk bug?
Unfortunately, I only now realized that my SATA HOTPLUG is enabled in my UEFI default settings and therefore is listed (correctly) as removeable device.

#SATA HOTPLUG disabled in UEFI settings

Re: GNOME mounts a disk that is not included in fstab

this would be a lsblk bug?

Ifff different sysfs paths have different values for what would be the same device/condition, that's not a userspace problem.
Is sda the nvme?

However,

I only now realized that my SATA HOTPLUG is enabled in my UEFI default settings and therefore is listed (correctly) as removeable device.

the patch does what it's expected to do - so no mystery there.

Re: GNOME mounts a disk that is not included in fstab

no, it is not a nvme drive. my sda is a 2.5"  sata ssd.

for the nvme, there are more files that get checked by lsblk. => consistent information

$ strace lsblk -d -o NAME,HOTPLUG |& grep nvme
openat(AT_FDCWD, "/sys/block/nvme0n1/hidden", O_RDONLY|O_CLOEXEC) = 5
openat(AT_FDCWD, "/sys/block/nvme0n1/dev", O_RDONLY|O_CLOEXEC) = 5
openat(AT_FDCWD, "/sys/dev/block/../../devices/pci0000:00/0000:00:02.2/0000:11:00.0/nvme/nvme0/nvme0n1/removable", O_RDONLY) = 3
openat(AT_FDCWD, "/sys/dev/block/../../devices/pci0000:00/0000:00:02.2/0000:11:00.0/nvme/nvme0/removable", O_RDONLY) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)

nvme0n1       0
$ tail /sys/class/block/nvme0n1/removable

for completness, here is the output with linux-lts. Everything is at least consistent here.

Re: GNOME mounts a disk that is not included in fstab

Don't grep for sda, https://bbs.archlinux.org/viewtopic.php … 0#p2175940 should™ have listed some sda access but only holds sdb, sdc and the nvme
Post the entire strace on the 6.9 kernel so we can see what's going on there…

"sdaable"???

ls -lR /sys/dev/block/../../devices/pci0000:00/0000:00:02.1/0000:04:00.0/0000:05:0d.0/0000:10:00.0/ata1/host0/target0:0:0/0:0:0:0/block/

There's similar nonsense going on w/ sdc

openat(AT_FDCWD, "/sys/dev/block/../../devices/pci0000:00/0000:00:08.1/0000:12:00.4/usb6/6-1/6-1:1.0/host6/target6:0:0/6:0:0:0/block/sdcle/removable", O_RDONLY) = -1 ENOENT (No such file or directory)

God knows where the "sdaable" comes from, but it spoils the lsblk output - and looks like an lsblk bug, yes.
#29 btw had some spurious unicode stuff in there, so it's likely some  buffer overflow.
Do you also get that for only "lsblk -d -o HOTPLUG" or "lsblk -o NAME,HOTPLUG" (nb. I skipped the "d")

Re: GNOME mounts a disk that is not included in fstab

I meant whether the bogus paths show up in the strace w/ the limited options.
