SOLVED: Separate partitions mistakenly mounted inside of /

[tigerflag]

For some reason, my separate /data and /music partitions have been created as directories inside of / . As I've been ripping music to /music, thinking it was a separate partition, it has totally filled up my / partition.

/dev/sda1 = / with 10.7 GB. It should have a lot of empty space but is full.

Should be separate partitions:

/dev/sda5 = /data with 5 GB. For my personal files, instead of using /home.

/dev/sda6 = /music. Should be 94 GB. For music and videos.

Somehow both of these partitions have been mounted INSIDE of /, causing / to become totally full.
/music got allotted 6 GB inside of / ; it is completely filled up.

When I try to mount the partition /dev/sda6 I get the error:

Failed to mount "94G Volume".
mount: wrong fs type, bad option, bad superblock on /dev/sda6,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.

dmsg shows the following error from bootup:

Code: Select all

XFS: unknown mount option [discard]

So I just changed fstab to remove the "discard" option for /dev /sda/6

How do I get the system to see and automount /data and /music as separate partitions outside of / ?

Here is fstab:

Code: Select all

/dev/sda7        swap             swap        defaults,discard         0   0

#/dev/sr1        /mnt/dvd	      auto        auto,users,rw,exec  0  0
#/dev/cdrom      /mnt/cdrom       auto        noauto,owner,ro  0   0

Thanks for your help.

What happened when you rebooted? Was the behaviour with sda6 the same? Was /music still mounted under /?

I'm no expert on fstab (wikipedia has quite a good page on it I think) but the first thing I'd suggest would be to remove that "discard" option, from the entries for both partitions. Then test again and report what happens.

Thanks for jumping in, mimosa.

Rebooted and yes, /music and /data are still mounted under / instead of as separate partitions.

Reading showed me that "discard" is not an option for XFS, so I removed it from fstab. But since /sda5 is formatted with ext4, and "discard" is generally recommended for that filesystem when using a SSD, I've left it in for now.

Here's dmsg from the most recent boot, after getting rid of the "discard" option for /dev/sda6 (I know enough to find these log files, but not enough to interpret them). No more error with XFS, but lots of I/O errors with dev sr0, sector 0 (I was getting these errors before). I don't know what this means, or if it has anything to do with the problem of mounting /data and /music inside / instead of as separate /sda5 and /sda6 partitions. :

[mimosa]

I tried it here ( it so happens my sda6 is also xfs) and it worked fine with "defaults", but not when I copied your settings. I hope that gives you a useful starting-point.

Code: Select all

mimosa[~]$ cat /etc/fstab
/dev/sda7        /                xfs         defaults         1   1
/dev/sda6        /temp            xfs         noatime,auto,user,rw,exec 1  2
#/dev/cdrom      /mnt/cdrom       auto        noauto,owner,ro,comment=x-gvfs-show 0   0
/dev/fd0         /mnt/floppy      auto        noauto,users,rw,umask=00 0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
tmpfs            /dev/shm         tmpfs       defaults         0   0
mimosa[~]$ mount

[tigerflag]

Figured it out (with help). fstab was wrong:

Code: Select all

/dev/sda5        /data            ext4        auto,user,rw,exec,discard 1  2
/dev/sda6        /music           xfs         noatime,auto,user,rw,exec 1  2

should have been:

Code: Select all

/dev/sda5        /mnt/data            ext4        auto,user,rw,exec,discard 1  2
/dev/sda6        /mnt/music           xfs         noatime,auto,user,rw,exec 1  2

Thanks for your help.
