Example below using the fallocate command (man 1 fallocate) for simplicity; the issue is with the logic backing the system call. chathaway@bender:~/temp$ fallocate -l 1GB example.img chathaway@bender:~/temp$ mkfs.xfs example.img meta-data=example.img isize=512 agcount=4, agsize=61035 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=0, rmapbt=0, reflink=0 data = bsize=4096 blocks=244140, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=855, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 chathaway@bender:~/temp$ sudo modprobe loop chathaway@bender:~/temp$ mkdir mnt chathaway@bender:~/temp$ sudo mount -o loop ./example.img ./mnt/ chathaway@bender:~/temp$ cd mnt chathaway@bender:~/temp/mnt$ sudo fallocate -l 768MB -o 0 hello.txt chathaway@bender:~/temp/mnt$ sudo fallocate -l 768MB -o 0 hello.txt fallocate: fallocate failed: No space left on device chathaway@bender:~/temp/mnt$ df -h . Filesystem Size Used Avail Use% Mounted on /dev/loop0 951M 766M 185M 81% /home/chathaway/temp/mnt Expected behaviour: because we allocate 768MB starting at offset 0, and have 951MB on the disk, we would expect that the allocation should be fine. Other filesystem behave this way (for example, ext4).
