.schema not writing to LTO_LOGS

[BleakleyMcD]

schema files are not writing to the specified LTO_LOGS directory as specified in mmconfig. I can't figure out why. other log files such as writelto.txt and readback.md5 are writing to the correct directory. .schema files are defaulting to $HOME/Documents

[dericed]

uh oh. Do they write when LTO_LOGS is set but not when it is unset?

[BleakleyMcD]

They write when LTO_LOGS is set. In our case this is to something other than $HOME/Documents I haven't checked when LTO_LOGS is unset.

But the issue we have is that they do not write to the specified LTO_LOGS directory, but to the default of $HOME/Documents

This is weird because everything else that is supposed to write to LTO_LOGS does write to the correct, set directory. I can't see why .schema files are going rogue.

@dericed The schema file will only write after the tape is ejected. I tried moving everything in writelto before case "${TAPE_EJECT}" in y|Y) umount "${TAPE_PATH}" ;; *) echo "Done writing but not ejecting ${TAPE_SERIAL}." ;; esac but the schema file still wont' write until the tape ejects and when it does write still writes to $HOME/Documents and not to the location defined for $LTO_LOGS in mmconfig. I think the timing of the schema file writing after tape eject and the writing to the wrong location may be connected. I can't figure out how or why.

@BleakleyMcD, if you could submit a PR, that would be indeed fantastic!

[BleakleyMcD]

@retokromer if I write one that solves the issue I will 😊

[retokromer]

@BleakleyMcD I’m teaching in Chennai at the moment, and I cannot do it myself. Yet I’m happy to review, if you can do it. Thank you also for opening the issue.

[retokromer]

I guess, this is resolved in https://github.com/amiaopensource/ltopers/pull/128.

[BleakleyMcD]

Actually, I don't think either issue is resolved with #128 , unfortunately. I will check momentarily.

From earlier:

@dericed The schema file will only write after the tape is ejected. I tried moving everything in writelto before case "${TAPE_EJECT}" in y|Y) umount "${TAPE_PATH}" ;; *) echo "Done writing but not ejecting ${TAPE_SERIAL}." ;; esac but the schema file still wont' write until the tape ejects and when it does write still writes to $HOME/Documents and not to the location defined for $LTO_LOGS in mmconfig.

[retokromer]

Thank you, @BleakleyMcD, for reporting. I re-opened the issue then.

[BleakleyMcD]

Confirming with the latest ltopers that this is still an issue. The .schema file will not write until the tape has been ejected and, when it does, it writes to $HOME/Documents/ rather than the location specified for LTO_INDEX_DIR in mmconfig. I'm unsure if these two issues are directly related or not. Anyone else having the same behavior? I can't see what the issue is in the code.

[dericed]

Hey @BleakleyMcD, we started looking at it today. Hopefully will have a fix soon.

[BleakleyMcD]

Cooool! Thank you! Interested to see what the problem is...

Hi @BleakleyMcD, I think the issue may stem from the mountlto script, where LTO_LOGS was still assigned "${HOME}/Documents/lto_indexes." (May have been overlooked in this commit: d48143f?)

When I test it with that change (42f0e83), my .schema files get saved in the directory I specify in mmconfig; however, the .schema files do only write upon mounting and ejecting. (Not sure why as the default LTFS sync time is 5 min.)

Let me know if the first part works for you for now at least!

[BleakleyMcD]

Grrrreat! Thank you! I will test next week!

[retokromer]

Is this now resolved?

[retokromer]

And is the documentation up-to-date?

[aeschweik]

It is working for us at CUNY TV, but hoping it's also working at NMAAHC for @BleakleyMcD?

Thanks for the reminder about documentation. I made a pull request to update the readme (#139) but since I didn't put in the original changes, I'd love other sets of eyes to make sure it's correct.

[BleakleyMcD]

Almost! .schema files are writing to {LTO_LOGS} but not into {LTO_LOGS}/schema directory, which is the defined {SCHEMADIR}

Our .schema files still do not write until after the tape ejects which is kind of annoying but I'm not sure if that is fixable.

Thank you @aeschweik

[retokromer]

Is this still an issue with the last release (or the HEAD) or has it been resolved?

[aeschweik]

Should be fixed in #140, thanks @BleakleyMcD for pointing out my typo! Hope it's working on your end?

[retokromer]

This was my impression too. Thank you, @aeschweik, for confirming it!
