[SOLVED] "/media/Data" is filled with unexpected stuff.

Hello, the glorious Arch Linux community!

I'm setting a new arch system on an Asus eeepc 900. I have some issues, but more or less they are expectable and seems to be resolved with an extensible googlefication. But one thing has stumbled me.

Let me explain. Here is my fstab:

# 
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
devpts                 /dev/pts      devpts    defaults            0      0
shm                    /dev/shm      tmpfs     nodev,nosuid        0      0
#tmpfs                  /tmp          tmpfs     nodev,nosuid,defaults,mode=1777 0 0
/dev/sda1 / ext4 noatime,defaults 0 1
/dev/sdb1 /home ext4 relatime,defaults 0 1
/dev/sdb2 /tmp ext4 relatime,defaults 0 1
/dev/sdb3 /var ext4 relatime,defaults 0 1
/dev/sdb4 /media/Data ext4 relatime,defaults 0 1

/dev/sdb4 is supposed for all my data junk, so I decided to mount it into /media/Data (since as far as I know there is no special "junk" directory in LFH except for /home, but I'd like to keep /home separate).

Well. After a while I came to point when I need to setup my filesystem and what am I seeing in that directory?

ls -lg /media/Data

total 60
drwxr-xr-x  2 root   4096 Mar 12 23:54 backups
drwxr-xr-x 11 root   4096 May 20 19:05 cache
drwxr-xr-x 42 root   4096 May 21 00:16 lib
drwxrwsr-x  2 games  4096 Mar 12 23:54 local
drwxrwxrwt  2 root   4096 May 19 21:12 lock
drwxr-xr-x  8 root   4096 May 21 01:42 log
drwx------  2 root  16384 May 19 01:47 lost+found
drwxrwsr-x  2 mem    4096 May 21 00:09 mail
drwxr-xr-x  2 root   4096 May 19 01:48 opt
drwxr-xr-x  4 root   4096 May 19 22:36 run
drwxr-xr-x  4 root   4096 May 19 02:02 spool
drwxrwxrwt  2 root   4096 May 21 00:05 tmp

Wow, it seems like there is a separate partition or a new filesystem breeding. Rest assure, all these directories are filled with a lot of data. Where did it came from? And what has I done wrong? I expected this partition to e clean and tidy for my needs.

I am maybe a bit too amazed but I haven't seen any similar before so...it's a noob corner anyway.

Oh, sorry. It seems I found what's the problem. I'm somehow managed to swap my partitions.

fsidk -l:

Disk /dev/sdb: 16.1 GB, 16139354112 bytes
255 heads, 63 sectors/track, 1962 cylinders, total 31522176 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000c3cdc

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            2048     4196351     2097152   83  Linux
/dev/sdb2         4196352     6293503     1048576   83  Linux
/dev/sdb3         8390656    31520767    11565056   83  Linux
/dev/sdb4         6293504     8390655     1048576   83  Linux

Partition table entries are not in disk order

That's it, sdb4 which is supposed to be my junk holder is now on the sdb3's place. And sdb3 which is for /var is mutually.
Looks like I has failed somewhere with the disk partition.

Anyway, can you recommend any safe method to rename partitions? It would be very appreciated.

run fdisk, and chose 'x' for expert mode and then 'f' to fix partition order. it's that simple and i only learned it a couple of weeks ago...

Might want to also consider referring to your partitions in fstab by using UUID rather than sd__ names

Thanks, it works!

Yes, I should consider that. I just used to /dev/sdX labels for simplicity.
