Re: [PLUG] Help with weird device errors
It might be unrelated. Or maybe somehow touching a disk is triggering a probe of the floppy. Just wild speculation. Trying to disable the drive in bios or rmmod'ing the floppy driver might change the behavior.

Re: [PLUG] Help with weird device errors
I did think of removing the floppy in BIOS, but the question still presents itself, why do I get errors when accessing a mounted disk?

[PLUG] Help with weird device errors
I am setting up a file server, currently Ubuntu Server 22.04. I have three 1TB data disks, two act normally, the third is telling me there are errors on the floppy device. Could someone shed some light on this? Thanks. The disks are in an LVM volume group, the logical volumes are specified as the whole disk to isolate one from the other. They have an XFS file system. I was running Bonnie++ to exercise the disks. Here is the dmesg output. This is repeatable.
