[Help] Home Assistant keeps crashing with the error "Buffer I/O error on device sda" in VirtualBox

[nomadfromx]

I installed a new virtual machine with Home Assistant from scratch (by importing an .ova file) in TOS6. After that, I restored a backup of my HA version. Now, once or twice a day, this version of the virtual machine crashes with a "Buffer I/O error on device sda" error. After restarting, it works for a while (several hours), and then crashes again with the same error.
What could be causing this, and how can I fix it?
I also installed the same version of HA a year ago on the same version F6-424 MAX, and I didn't get any such errors.

This bug is associated with a bug in the operation of the btrfs system. The decision was made here - viewtopic.php?t=9215

[TMzethar]

This is possible. The load of BTRFS quota (btrfs-transact + btrfs-cleaner) may be very high, which could cause abnormal operation of the program from the day before yesterday. It is not recommended to run important programs while BTRFS quota is running.
