[Bacula-users] Bacula trying to write to device rather than mount point when using USB removable storage device

2007-01-18 Thread Benjamin Chambers

I'm doing some testing using v2.0.1 with a USB storage device.  In this case, 
it 
is an Iomega REV USB drive, but essentially, it could be any USB mass storage 
device.

Here is the configuration for the SD:

Device {
   Name = "_REV-USB"
   MediaType = "Iomega REV, USB"
   ArchiveDevice = "/dev/scd0"
   LabelMedia = "yes"
   RandomAccess = "yes"
   AutomaticMount = "yes"
   RemovableMedia = "yes"
   AlwaysOpen = "yes"
   DeviceType = "File"
   RequiresMount = "yes"
   MountPoint = "/var/bacula/mnt/rev/usb"
   MountCommand = "/bin/mount %a %m"
   UnmountCommand = "/bin/umount %m"
   MaximumVolumeSize = 70GB
}

Note, I put the DeviceType = "File" because otherwise Bacula thinks it is a DVD 
device and requires the "Write Command" directive.

I know you *could* put the 'ArchiveDevice' directive as the mountpoint (in this 
case /var/bacula/mnt/rev/usb/), however, then you would required the user to 
mount/umount the device, or use the RunBefore/After scripts.  Using the 
similarities to DVD and the additional directives when "Requires Mount" = yes 
is 
so much more elegant.

The problem is that Bacula is trying to write to the device (/dev/scd0), rather 
than the mount point.  The exact message when you try and label the volume is:

*
   Connecting to Storage daemon _REV-USB at 192.168.2.185:9103 ...
   Sending label command for Volume "Default-0001" Slot 0 ...
   3910 Unable to open device "_REV-USB" (/dev/scd0): ERR=dev.c:482 Could not
 open: /dev/scd0/Default-0001, ERR=Not a directory

   Label command failed for Volume Default-0001.
   Do not forget to mount the drive!!!
*

Has anyone got a USB mass storage device to work in 2.0.1?

Can anyone tell me if this is:

   a) Corrected by fixing my configuration
   b) Not an advised (or supported) method to mount USB mass storage devices
   c) An anomaly of the Iomega REV drive that is "part File, part DVD" in
  terms of how Bacula treats the device
   d) A bug

Thanks in advance.

Ben

This is a configuration error.

RequiresMount, MountPoint, unmountCommand are for DVDs only.

Yes. Or rather, the directives above don't apply to file storage.

Not me, but I know of others. Well, I kind of have - I operate simple 
usb disks but without any special consideration regarding mounting etc. 
These are setups where the disks are not meant to be removed.

Josh Fishers "Removable Disk Howto revised" is probably interesting for 
you - you find it searching in the list archives.

Yes. But probably diferent than what you intend.

Yes.

Don't know.

>d) A bug

No.

There's one other option, by the way: Try to understand how writing to 
DVD works for Bacula. Then, create a script similar to dvd-handler - 
basically, you could replace the invocations of growisofs with a cp, ge 
the available space using df, and so on.

My original idea was that dvd-handler could be used as a template for 
low performance storage systems like ftp, CD-RW and others, but 
currently Bacula reads directly, so whatever media you use, you must be 
able to mount it for reading. Writing can be done by a handler script.

Thanks for the reply Arno.

The manual certainly seems to be converging on the idea that USB and DVD SD's 
are handled similarly:

http://www.bacula.org/rel-manual/Storage_Daemon_Configuratio.html#SECTION00175

OK...not in the 18pt font header, but certainly in the content of the 
documentation in the following sections...

Hmmm

Confused which direction to take.

Right, but I guess the manual needs some work there. Or I'll have to 
look up Kerns mails regarding how he implemented better removable disk 
handling :-)

> OK...not in the 18pt font header, but certainly in the content of the

... because "Requires Mount = Yes|No
 You must set this directive to yes for DVD-writers, and to no for 
all other devices (tapes/files). This directive indicates if the device 
requires to be mounted to be read, and if it must be written in a 
special way. If it set, Mount Point, Mount Command, Unmount Command and 
Write Part Command directives must also be defined." does not make 
sense. Unless, of course, you take the path I mentioned - use a special 
handler script to copy part files (which is more or less nonsense).

Anyway, the above snippet states that when you set RequiresMount, the 
device "must be written in a special way". Which is not why you use 
removable USB devices... Also, it states that it must be set to no for 
files. Which contradicts the lines under the heading which you probably 
referred to.

I'm quite sure Kern presented his way of using removable USB storage 
devices, and I suppose Joshs HowTo might be interesting.

Use the OS udev feature, tell Bacula the USB is a file, point it at the mount 
point, and tell Bacula that it is removable, and things should more or less 
work out OK.  Tha is the OS will automatically mount it when it is plugged 
in, and Bacula will ask you to mount it when it is not there, you plug it in 
and the OS will mount it, then you enter "mount" in bconsole, and Bacula 
should be happy.  

If a different USB is mounted on the specified device (mount point), Bacula 
will scan it to see if there are any appendable volumes (essentially 
identical to the case of having a different tape in the drive). If there are 
appendable volumes on the currently mounted USB device, Bacula will use them, 
otherwise (provided you set it as removable), Bacula will request you to 
mount the proper volume.

As I read this thread I found that this directives (the wording) are not very 
chosen from a usability pov. There are many things that can/must be
mounted.

So I would suggest:

  * Rename this directive to "DVD Writer = Yes|No"

The Term "Requires Mount" can be implied by setting the "Mount
Point" and "(Un)Mount Command" directives. If those are set it should be 
clear to the user that bacula tries to use them...

This way, setting "DVD Writer" to "No" and not specifying 
"Mount/Unmount Command" bacula should write directly to a block
device without using any filesystem.

Then I could tell bacula which block device to use with the "Archive
Device" directive.

Would be a new Device Type "Device Type = Block" be useful/needed for that?


Another thing I was thinking of while looking at the Docs:

  "Random access = Yes|No"

Does this setting have some sort auf "Auto" setting when not set? If
not, wouldn't that make sense? Or in other words: Are there *any*
disadvantages in setting this to "Yes" for devices that support it?
If not it should be set to "Yes" automatically if its supported.
Maybe this directive could even be deprecated then ...

What do you think?

Cheers

Yes, that seems to be part of the problem.

Anyway, Kern explained how Bacula handles these directives, but I 
understand that he would rely on the OSes automountin mechanics.

I doubt that this will happen - Kerns is *really* conservative 
concerning changes to Bacula that create incompatibility.

Correct, but see above.

Dropping a directive might be easier than changing it, though - Bacula 
could still parse and understand it but simply ignore it... 
AcceptAnyVolume, anyone? ;-)

No, I don't think so...

Well, this directive is mainly to make Bacula work with devices where 
Random Accessibility can not be determined automatically. Which might be 
more than I think. Anyway, the device type configuration should make 
this one superfluous... I think it's a safe bet to say that File can be 
randomly accessed and Tape not and DVD needs special treatment.

Personally, I wouldn't worry about these directives. As long as Bacula 
can be set up according to your hardware - and I hope this is much 
clearer now, regardind removable disks - I'm satisfied.

I mainly think the manual needs refinement.
