How to permanently mount eSATA

[dan_bub]

Hi,
I would like to have my eSATA-drive mounted permanently, because Bubba2 hands out a new device name when i reboot my desktop machine, for exsample:

HDT722525DLA380 /dev/sdh4 unused ATA

turnes into

HDT722525DLA380 /dev/sdi4 unused ATA

The fstab shows:

Code: Select all

/dev/mapper/bubba-storage       /home   ext3    defaults                0       2

What do I have to set in to get the drive mounted permanently, so the scripts in crontab point to the right backup divice?
Thanks in advance

I don't understand - you reboot your desktop PC and it changes the device name on the Bubba? That makes no sense.

Does the Bubba not create a mount point in /home/storage/extern for your eSATA drive? That's how it works with USB drives and the names are consistent IME. All you should need to do is add that mount point to your fstab.

[dan_bub]

....That makes no sense.

I agree.

Does the Bubba not create a mount point in /home/storage/extern for your eSATA drive?

Yes, it does, but it somehow gets unmounted, and than a new device name is used. (see picture)

I am used to mount a samba share:

Code: Select all

//bubba/home/test   /media/bubba_test   cifs  rw,auto,username=test,password=test,uid=test,gid=users  0 0

Could that have an impact?

What he is saying is making a lot of sense. He is not taking about the mount point but rather the device file hence the path starts with /dev. Bubba 2 as I think all new distributions is using udev to attached devices and this can lead to different device names upon boot. So that mean you should not use /dev/sd something but rather use the unique UUID that each partition get. You should hence use the path below where you should exchange the <UUID> to the UUDI of the partition you want to use.

/dev/disk/by-uuid/<UUID>

You could either get the UUID by doing an

Code: Select all

ls -l /dev/disk/by-uuid

or running the blkid as root.

Code: Select all

su -
blkid /dev/sdh4

This is what "df" returns:

Code: Select all

and "ls -l /dev/disk/by-uuid" returns:

Code: Select all

And finaly the "blkid" command:

Code: Select all

bubba:/# blkid /dev/sdh4
/dev/sdh4: LABEL="bubba_rsync" UUID="6448261a-7170-4d7b-ae24-614a5c218a59" SEC_TYPE="ext2" TYPE="ext3"

I am a bit confused. How do I express that right so it fits for the fstab?

[RandomUsername]

Using your fstab entry above as an example, instead of this:

//bubba/home/test /media/bubba_test cifs rw,auto,username=test,password=test,uid=test,gid=users 0 0

Do this:

UUID=6448261a-7170-4d7b-ae24-614a5c218a59 /media/bubba_test cifs rw,auto,username=test,password=test,uid=test,gid=users 0 0

I would agree with that, but he's not talking about rebooting his Bubba, he's talking about rebooting his desktop PC.

[dan_bub]

ok, I was a bit slow, I have to use

Code: Select all

UUID="6448261a-7170-4d7b-ae24-614a5c218a59" 

I'll try that and post the result.

[dan_bub]

I would agree with that, but he's not talking about rebooting his Bubba, he's talking about rebooting his desktop PC.

Well since Bubba was not rebooted, my wild guess was the samba share and the reboot of the desktop PC.
It is a bit strange, that Bubba keeps the old eSATA-mounts listed so.

[dan_bub]

Seems that I can't handle this UUID-thing.
I tried the unmodern way:

Code: Select all

bubba:/# mkdir -m 775 /home/storage/extern/bubba_rsync
bubba:/#chown admin /home/storage/extern/bubba_rsync
bubba:/#chgrp users /home/storage/extern/bubba_rsync

I registered the new mountpoint with fstab:

Code: Select all

bubba:/etc# cat fstab
/dev/sda1       /       ext3    noatime,defaults        0       1
/dev/mapper/bubba-storage       /home   ext3    defaults                0       2
/dev/sda3       none    swap    sw                      0       0
usbfs           /proc/bus/usb   usbfs   defaults        0       0
/proc           /proc   proc    defaults                0       0

So this is working. To test it, I come to my acctual goal backing up the users Mail-folder:

Code: Select all

bubba:/home/storage/extern# rsync -a /home/test/Mail /home/storage/extern/bubba_rsync/test

bubba:/home/storage/extern/bubba_rsync/test# dir
Mail

I guess it is oldfashion, but it works until now. No idea If it conflicts with "dev/mapper/bubba-storage" at some point?
But why are those disk_0-9 listed? The eSATA-drive has only 4 partitions on it, so it must be some old stuff?
Do I have to remove them manually?

[ryz]

The easy way to use the UUID thing is to change the line

Code: Select all

/dev/sdh4 /home/storage/extern/bubba_rsync rw,auto  0 0

to

Code: Select all

/dev/disk/by-uuid/6448261a-7170-4d7b-ae24-614a5c218a59 /home/storage/extern/bubba_rsync rw,auto  0 0

Or I guess an more correct way to write this in the fstab file is

Code: Select all

UUID=6448261a-7170-4d7b-ae24-614a5c218a59 /home/storage/extern/bubba_rsync rw,auto  0 0

Don't ask me what all the other disk and stuff is because I have no clue.

Yes, you are right, now it works. The only thing missing was the filesystem, so I changed it to:

Code: Select all

UUID=6448261a-7170-4d7b-ae24-614a5c218a59 /home/storage/extern/bubba_rsync  ext3   defaults   0 0

Everything is working now.

Thanks to everybody for listening and help.
