USB Drives mounting differently each reboot

[kilroy]

Good day everybody,

I have a problem that was fixed under Edgy, but has returned since I upgraded to Feisty.

The Problem:
I have 3 USB external Drives, I want them to mount at the same mountpoints each time the system either upgrades or reboots.
I have those drives setup in my smb.conf file to allow for my windows machine to access the mp3's / backups / general shares.

The Solution that worked under edgy:
Setup the /etc/fstab file with static mountpoints.

This worked fantastically. Reboot after reboot - always remained the same 3 shares in the correct ext drives.

This is the relevant part of my fstab file

/dev/disk/by-id/usb-SAMSUNG_SP2514N_0-part1  /media/disk  auto auto,user,exe
c,rw,sync 0 0
/dev/disk/by-id/usb-WD_2500JB_External_5743414C3733343437353530-part1 /media/dis
k-1 auto auto,user,exec,rw,sync 0 0
/dev/disk/by-id/usb-WDC_WD32_00SB-01KMA0-part1 /media/disk-2 auto auto,user,exec
,rw,sync 0 0

and the relevant sections of my smb.conf

[General]
path = /media/disk-1/
read only = no
create mask = 0644
force user = andrew
guest ok = yes
case sensitive = no

[Backups]
path = /media/disk/
read only = no
create mask = 0644
force user = andrew
guest ok = yes
case sensitive = no
strict locking = no

[MP3]
path = /media/disk-2/
read only = no
create mask = 0644
force user = andrew
guest ok = yes
case sensitive = no

Now each time that I reboot my feisty box (1 or 2 times a month - since upgrade)
I have to go and modify the smb.conf, restart samba, then redo my windows mapped shares so that my backup software will actually send the backups to the correct share.

Any ideas?

Thanks
Kilroy

Use UUIDs rather than device nodes?

EDIT: Wait. You're not using device nodes. Try UUIDs anyway.

/dev/disk/by-id/usb-SAMSUNG_SP2514N_0-part1 /media/disk [...]

Just to make sure I get your point:

What does more /etc/mtab | grep '/media/disk' result in before and after reboot, respectively ...?

Re: USB Drives mounting differently each reboot

Before Reboot

andrew@speedy:~$ more /etc/mtab | grep '/media/disk'
/dev/sdc1 /media/disk ext3 rw,nosuid,nodev,sync 0 0
/dev/sda1 /media/disk-1 ext3 rw,nosuid,nodev,sync 0 0
/dev/sdb1 /media/disk-2 ext3 rw,nosuid,nodev,sync 0 0

After Reboot

andrew@speedy:~$ more /etc/mtab | grep '/media/disk'
/dev/sdc1 /media/disk ext3 rw,nosuid,nodev,sync 0 0
/dev/sda1 /media/disk-1 ext3 rw,nosuid,nodev,sync 0 0
/dev/sdb1 /media/disk-2 ext3 rw,nosuid,nodev,sync 0 0

Before Reboot

After Reboot

Am I dumb or what? To me, both listings look the same

Or do you want to tell me / us that in either case e.g. /dev/sdc1 points to an other disk

Re: USB Drives mounting differently each reboot

Everything looks fine to me.

Are you sure that they're moving around?

Re: USB Drives mounting differently each reboot

They were, it usually happens after a patch / update has been installed.

THough I guess that is really the only time that I reboot this box.

They were

Weird ... and the IDs remain(ed) unchanged?

Plan B: reboot with the drives switched off (!).
