1) Thanks for filing bugzilla report 2) Component is wrong, as filesystem is component which owns and creates basic system directories and has nothing to do with filesystems on your harddrive 3) You could use disk UUID in /etc/fstab if you need the consistency anyway (workaround) From your report it is hard to say where the real issue is, it could be either hw issue, udev, kernel issue or even something else. Let's try udev, but be prepared that Harald will probably need more information. (sorry Harald if udev is wrong component for that :) ) Please always use predictable names like UUID=, LABEL=, /dev/disk/by-*/* in fstab, never the kernel device name. There is no, and never was a guarantee that the discovery order of devices in the kernel produces the same names across reboots. You can just plug in a USB storage device and all the names change. That's not a bug, it's the expected behaviour. My problem occurs with an internal second drive, not USB. I thought that internal drives were supposed to stay constant. Sometimes, when external devices are connected they mix up all device names, because they are found before the internal ones. If devices are connected to different buses ATA host adapter, SCSI host adapter, USB, Firewire, they all have no predictable probing order, it all depends which bus driver is the first one that gets initialized during bootup, and all run in parallel. Nothing guarantees any order here, the kernel device names can not be used to identify a device across reboots, that's why the default installation uses UUID= in fstab for many years. |
