/opt/firebird/bin/gbak -v -C -user sysdba -pas 'XXXXX' /DB/MATest.fbk /dev/sda1

gbak:opened file /DB/MATest.fbk

gbak:Exiting before completion due to errors

Even if there is no data in the RawDevice, the switch "-Rep" must be used. Is that the way it is supposed to be?

/opt/firebird/bin/gbak -C -REP -user sysdba -pas 'XXXXX' /DB/MATest.fbk /dev/sda1

This will work.

I can not reproduce this. Tried once again:

fbs3 /usr/home/firebird/HEAD/gen/Debug/firebird/bin # ./gbak -v -C -user sysdba -pas masterkey e.gbak /dev/sdb3
gbak:opened file e.gbak
gbak:transportable backup -- data in XDR format
gbak: backup file is compressed
gbak:backup version is 11
gbak:created database /dev/sdb3, page_size 8192 bytes
gbak:started transaction
gbak:restoring domain FIRSTNAME
..................
gbak:finishing, closing, and going home
gbak:adjusting the ONLINE and FORCED WRITES flags
fbs3 /usr/home/firebird/HEAD/gen/Debug/firebird/bin #

I can find particular place in code where error
gbak: ERROR:I/O error during "open O_CREAT" operation for file "/dev/sda1"
is raised but I have no idea why does engine reach that line on your box.

To help ypu I need a way to reproduce this.

BTW, what version did you check last time? Snapshot with the fix?

Sorry, but I didn't get an email that there was a new message.
I only tested it with the Firebird 4 snapshot "Firebird-4.0.0.2439".
