Hi, I created a filesystem and mounted it with compress-force=lzo. Then I did:
# df -h . Filesystem Size Used Avail Use% Mounted on /dev/loop0 100M 4.1M 96M 5% /mnt # yes "Hello World" | dd of=/mnt/test iflag=fullblock bs=1M count=20 status=none yes: standard output: Broken pipe yes: write error # sync; ls -l ; df -h . total 20480 -rw-r--r-- 1 root root 20971520 Oct 27 13:48 test Filesystem Size Used Avail Use% Mounted on /dev/loop0 100M 4.7M 96M 5% /mnt so far so good ... # touch test2; chattr +C test2 # dd if=test of=test2 conv=notrunc bs=1M iflag=fullblock oflag=append status=none # sync; ls -l ; df -h . total 40960 -rw-r--r-- 1 root root 20971520 Oct 27 13:51 test -rw-r--r-- 1 root root 20971520 Oct 27 13:51 test2 Filesystem Size Used Avail Use% Mounted on /dev/loop0 100M 25M 76M 25% /mnt oops, no compression. Is this intended?
