Thanks to Markus and Moritz, I did not read carefully enough the last
section of the r.region manual.
> Memory has nothing to do with the error "ERROR: Error writing segment
> file", this is an error while writing to disk (not enough disk
The error message appears when the i.rectify is loading the image.
I have enough disk space, I hope:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda6 33031204 919284 30433984 3% /
/dev/sda9 359924668 41523544 300118004 13% /home
/dev/sda8 49548372 4450220 42581220 10% /var
The raster is 1351510007 bytes, users have no quota.
> i.rectify has a separate option controlling memory usage,
> default is 300MB; this does not affect disk space requirements.
I tried to change it, and closed all other applications, so the 3.2G
of memory was used for X11, FWVM2 and GRASS, and a few small applications
in background (FWVM2 buttons and panel etc).
The other PC with 4G memory did use my disk over nfs, thus the difference
was in memory and the space for temporary files.
