Looks like writing 1KB isn't enough: Filesystem Size Used Avail Use% Mounted on /dev/dm-0 9.1G 8.6G 4.0K 100% / We should probably write a block worth of data. Block size can be fetching using statvfs (stat -f -c %s /tmp) from the shell, python has os.statvfs IIRC) Better idea - rip the test out and use the disk monitoring support instead. Totally forgot that existed...
From local.conf:
#
# Disk Space Monitoring during the build
#
# Monitor the disk space during the build. If there is less that 1GB of space or less
# than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
# shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
# of the build. The reason for this is that running completely out of space can corrupt
# files and damages the build in ways which may not be easily recoverable.
BB_DISKMON_DIRS = "\
STOPTASKS,${TMPDIR},1G,100K \
STOPTASKS,${DL_DIR},1G,100K \
STOPTASKS,${SSTATE_DIR},1G,100K \
ABORT,${TMPDIR},100M,1K \
ABORT,${DL_DIR},100M,1K \
ABORT,${SSTATE_DIR},100M,1K"
Adding a pair of entries for /tmp (100mb/10mb?) seems like a sensible solution.
