device is missing in df
I have installed Ubuntu 7.10 from CD on a SATA-drive:
Everthing seemed OK until I looked at the drive with GParted which complained about missing mountpoint for /dev/sda1. fdisk -l gives: Device Boot Start End Blocks Id System /dev/sda1 * 1 60424 485355748+ 83 Linux /dev/sda2 60425 60801 3028252+ 5 Extended /dev/sda5 60425 60801 3028221 82 Linux swap / Solaris /etc/fstab gives: # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/sda1 UUID=0e21f8c5-6e90-4434-96dc-d98a0b9ce7ee / ext3 defaults,errors=remount-ro 0 1 # /dev/sda5 UUID=ca1df9d2-e38d-4ef4-830a-d63ea1be4426 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0 but ... df -h gives: Filesystem Size Used Avail Use% Mounted on varrun 505M 240K 505M 1% /var/run varlock 505M 0 505M 0% /var/lock udev 505M 72K 505M 1% /dev devshm 505M 0 505M 0% /dev/shm lrm 505M 34M 471M 7% /lib/modules/2.6.22-14-generic/volatile Where is /dev/sda1 in df listing Someting is very wrong but I can't figure out how to correct it ... |
What do you get when you run:
$ mount That should show all mounted file systems and their mountpoints. You are using UUIDs instead of device files for mounting in fstab. That may be causing the confusion with df and gparted. |
mount gives:
proc on /proc type proc (rw,noexec,nosuid,nodev) /sys on /sys type sysfs (rw,noexec,nosuid,nodev) varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755) varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777) udev on /dev type tmpfs (rw,mode=0755) devshm on /dev/shm type tmpfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) lrm on /lib/modules/2.6.22-14-generic/volatile type tmpfs (rw) securityfs on /sys/kernel/security type securityfs (rw) nfsd on /proc/fs/nfsd type nfsd (rw) still no device ... hmmm ... what I don't understand is following: I have another Linux box in my network that don't give me any alarm from GParted and df, mount is OK and fstab is also using UUID. Here is the system that is OK: fstab: # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/sda1 UUID=fbadb609-e209-4502-a4ca-acc939d8a8c3 / ext3 defaults,errors=remount-ro 0 1 # /dev/sda5 UUID=feabf38d-0ff6-45d3-ab11-fa7149a3bfc5 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto 0 0 mount: /dev/sda1 on / type ext3 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) /sys on /sys type sysfs (rw,noexec,nosuid,nodev) varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755) varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777) udev on /dev type tmpfs (rw,mode=0755) devshm on /dev/shm type tmpfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) lrm on /lib/modules/2.6.22-14-generic/volatile type tmpfs (rw) securityfs on /sys/kernel/security type securityfs (rw) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) df -h: Filesystem Size Used Avail Use% Mounted on /dev/sda1 224G 32G 181G 16% / varrun 2.0G 240K 2.0G 1% /var/run varlock 2.0G 4.0K 2.0G 1% /var/lock udev 2.0G 88K 2.0G 1% /dev devshm 2.0G 0 2.0G 0% /dev/shm lrm 2.0G 38M 1.9G 2% /lib/modules/2.6.22-14-generic/volatile I cannot see what is the difference between the system that gives me problems and the system that is OK when it comes to fstab. The 'problem system' is running as a nfs-server ... could that cause the problem ? What do you recommend ? |
Problem SOLVED.
The problem occured when I install a new system (since I upgraded my disk) and restored my backup ... unfortunately with the old fstab (all my mountpoints were there). What happen was that the UUID in /boot/grub/menu.lst and UUID in /etc/initramfs-tools/conf.d/resume differed from UUID from old fstab. Changing UUID:s in fstab made a difference ... now I am airborne again |
