Reminder writes could not be disabled when using a read-only filesystem #696

Closed NilsRo closed 1 year ago

NilsRo commented 1 year ago

Hi,

I tried to disable the "reminder" as it tries to write to a file that is not possible in my read-only setup to avoid writes to the SD Card. I set the parameters like this but it does not stop trying.

DEFAULT_RESTORE_REMINDER_INTERVAL=0 DEFAULT_RESTORE_REMINDER_REPEAT=0

In the FAQ and parameter list I did not find how to disable the reminder. Is that actually possible?

Error: /usr/local/bin/raspiBackup.sh: line 7982: /var/lib/raspiBackup/restore.reminder: Read-only file system

raspiBackup.log

Cheers, Nils

The restore reminder just reminds you to execute a restore from time to time. I checked your debug log but I don't find any message which puzzles you and you want to get rid of :thinking:

as it tries to write to a file that is not possible in my read-only setup to avoid writes to the SD Card.

You can use option -u or config option DEFAULT_EXCLUDE_LIST to exclude any files from the backup. Not sure whether this will solve your issue because I frankly don't get you issue :cry: Please provide more details.

I just detected I missed the error message :cry:

I use raspiBackup on systems which don't have RO filesystems configured. Looks like I have to persist the reminder file in some other directory which is not set to RO. Did you configure the RO filesystem with raspi-config? Then I can reproduce your issue and change the location of the reminder file accordingly

Set it up with another guide (I can enable rw easily with bash integration: https://www.hamspirit.de/10871/raspberry-pi-mit-read-only-filesystem-optimieren-ideal-fuer-den-portablen-einsatz/) but in my opinion /tmp is mapped to tmpfs everytime. Perhaps it would be the easiest to disable reminder somehow via settings.

PS. Or put it into the backup directory as it should be writeable. Anyway both options to disable the reminder completely or change file location would be nice for RO systems.

That will work. But I changed the code an now the reminder stuff is just skipped. Please test the fix with 

curl -s https://raw.githubusercontent.com/framps/raspiBackup/master/scripts/raspiBackupDownloadFromGit.sh | bash -s -- master_696
