Thank you for your replies. Maybe the /boot/grub/device.map is interesting, because the SSD (sdc) is missing in there (!): blackbox:~# cat /boot/grub/device.map (hd0) /dev/disk/by-id/ata-ST3120023A_3KA1BNGQ (hd1) /dev/disk/by-id/ata-SAMSUNG_HD501LJ_S0MUJ1FPB79563 blackbox:~# How is the device.map file updated? By whom? The information Andrei asked for is also not fully conclusive for me in particular in conjunction with the Ted Tso's bug report http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=9;bug=616317 as pointed out by Florian [the full data are appended]: I tested three setups: 1) Setup: rootflags and UUID fstab entry (the one I had before): Result: no configured options for root filesystem rd@blackbox:~$ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-2.6.32-5-686-bigmem root=UUID=4a4eb948-2d2b-4188-96ae-76a3776ae69c ro quiet elevator=noop rootflags=noatime,discard,data=ordered,errors=remount-ro rd@blackbox:~$ from /etc/fstab: UUID="4a4eb948-2d2b-4188-96ae-76a3776ae69c" / ext4 noatime,discard,data=ordered,errors=remount-ro 0 1 rd@blackbox:~$ mount rootfs on / type rootfs (rw) [...] 2) Setup: rootflags and /dev/... fstab entry Result: root filesystem gets configured options (in addition the findfs issue goes away, I posted at http://lists.debian.org/debian-user/2011/05/msg00544.html ) rd@blackbox:~$ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-2.6.32-5-686-bigmem root=UUID=4a4eb948-2d2b-4188-96ae-76a3776ae69c ro quiet elevator=noop rootflags=noatime,discard,data=ordered,errors=remount-ro From /etc/fstab: /dev/disk/by-uuid/4a4eb948-2d2b-4188-96ae-76a3776ae69c / ext4 noatime,discard,data=ordered,errors=remount-ro 0 1 rd@blackbox:~$ mount /dev/sdc1 on / type ext4 (rw,noatime,discard,data=ordered,errors=remount-ro) 3) Setup: no rootfsflags and /dev/... fstab entry Result: root filesystem gets configured options rd@blackbox:~$ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-2.6.32-5-686-bigmem root=UUID=4a4eb948-2d2b-4188-96ae-76a3776ae69c ro quiet elevator=noop from /etc/fstab: /dev/disk/by-uuid/4a4eb948-2d2b-4188-96ae-76a3776ae69c / ext4 noatime,discard,data=ordered,errors=remount-ro 0 1 rd@blackbox:~$ mount /dev/sdc1 on / type ext4 (rw,noatime,discard,data=ordered,errors=remount-ro) The result of the third configuration (and to some extend also the first configuration) is unexpected for me in the bug report from Ted Tso: "[...] Debian simply doesn't support the mount options for the root file system in /etc/fstab having any effect on how the root file system is mounted. The root file system is mounted by the kernel, and the mount options used by the kernel are specified by the rootflags= option on the kernel's boot command line. [...]" Does anybody understand how both, my data and Ted's report make sense? Can we be sure that the output of the mount command reflects the system state (or does it even display wrong information in some configurations I did)?
