"Device /dev/sr0 does not become ready:" when "eject -t" used in BASH

I know that this is below the level typically seen in this subforum, and if this is is the wrong place I'm sorry. This was my best guess as to where this topic should go.

I'm write a small collecting of scripts that automate the process of archiving my data onto BD-R, which includes burning, and checking. The script in question burns an previously created image, and then checks the image.

After growisofs finishes burning it ejects the disc. I close the drive with "eject -t", however DVDisaster isn't able to find the drive afterwards. At first I added some "wait" and "sleep" commands in hopes that this would fix the issue, but it does not.

I also tried running "eject -t" and then running the script with "eject -t" commented out, and this error does not occur.

The first block of code is the full script, while the second one is the part I feel is relevant.

[edit2] I forgot to ject the tray before running the script. That's why it didn't fail this time. the output is below

Re: "Device /dev/sr0 does not become ready:" when "eject -t" used in BASH

Is the "Device /dev/sr0 does not become ready:" in the post title part of the actual output of the script? If so, the full output would provide more context to help figure out what's happening. In particular, is there some indication of what specific command is failing? If this reliably happens every time you run the script, I would suggest just stepping through the script executing each command individually to see where it's failing. If you know what line is failing, does running that command with a -v flag provide any further information?

Also, you say you're running "eject -t" (retract tray), but your script has "eject -T" (toggle tray between open/closed). As far as I understand, the latter just calls the former to retract the tray, so I'd be surprised if there were a material difference, but you might see if using eject -t in your script makes a difference.

I have no idea why its working now since i didn't actually change anything in the script.

Re: "Device /dev/sr0 does not become ready:" when "eject -t" used in BASH

Sorry for the lag in responses. I don't have much experience with optical drives, so I'm probably a bit out of my depth on this one. One obvious thing to check, if you haven't already, is whether the drive is really just taking a really long time to get ready for some reason. If you do the burn, close the tray, and then wait a few minutes, does the read work? If so, then you probably need to just figure out how long it takes and lengthen the pause in your script accordingly, and maybe look into what might cause the drive to be slow to get ready (I have no real idea of what the process there is).

If it doesn't work, maybe check whether the problem is specific to images burned in this way, or to this kind of disk. For example, can you read a commercial BD? If the drive also handles CD/DVD-R, if you burn an image to one of those, can you then read it back with no problem?

Re: "Device /dev/sr0 does not become ready:" when "eject -t" used in BASH

May be I am not getting your issue completely but the simplest approach that springs to my mind for a "wait for drive ready" approach would be grabbing for the output of mount itself for the cd drive.

Something like "mount  | grep /dev/sr0".

If you wait until e.g. /dev/sr0 is listed under the mounted devices, the drive is ready for your verification.

Re: "Device /dev/sr0 does not become ready:" when "eject -t" used in BASH

No need for anyone to apologize for a delay, least of all those who are helping.

I'm not sure that waiting for "mount  | grep /dev/sr0" to display something other than "" will do much, since physically closing the tray then starting a separate script to do the checking works. Using a sleep of 60 instead of 5, which is much longer than it takes me to close the tray with eject -t outside of a script and run the script manually, does work, though its a bit befuddling as to why.

While this thread seems to be solved, I would like to know the following code doesn't cause the script to get stuck in a loop until the drive is ready.

while [ "mount  | grep /dev/sr0" = "" ]; do
	sleep 5
done

The script hits that and then goes right past it. While a few extra seconds doesn't mean too much extra time considering I'm writing 25GB to the disc, then reading it back twice and running 5 different hashes to verify everything is okay, I still would like to have that working as it seems to be a surer way to ensure the script executes corrected.

Also, are there any good tutorials on how to integrate Windows command line programs, using wine, into a Linux bash script? I used the information on WineHQ, but it seems as if the Windows command line syntax is incompatible with BASH's. Currently I'm running ImgBurn separately with Wine in its GUI form.

Re: "Device /dev/sr0 does not become ready:" when "eject -t" used in BASH

I don't have much time to think more about the long time it takes for the drive to become ready, but as for the while loop, you're just comparing the literal string "mount | grep /dev/sr0" to the empty string, which will always return false. To compare the output of the command, you can use backticks:

 while [[ `mount | grep /dev/sr0` == "" ]]
    sleep 5
done

I _think_ you also need double brackets [[ ]] instead of single, though I'm not 100% on that.

That doesn't seem to work. I found a resource on the use of double brackets and such. I'll look over it sometime next week. Thank you though.

edit] At least on my system, mount | grep /dev/sr0 == "", is always true. I have /dev/sr0 auto noauto,user,ro 0 0 in my fstab and so it never automounts. If the loop is properly constructed then the script should get stuck in that look.
