[virt-tools-list] virt-sparsify TMP full

[Evaggelos Balaskas]

it seems that when TMP is full (i use tmpfs)

virt-sparsify doesnt exist with an error but it freezes


my last test is this:

Fill free space in /dev/vg_centos63/lv_root with zero ...
libguestfs: send_to_daemon: 52 bytes: 00 00 00 30 | 20 00 f5 f5 | 00
00 00 04 | 00 00 01 37 | 00 00 00 00 | ...

guestfsd: main_loop: new request, len 0x30
random filename: /sysroot//3x23hphk.zhd

i am sorry for the spam,

i forgot to mention that i use TMPDIR to change the tmp dir

export -p TMPDIR=/vm/tmp

so that virt-sparsify do its magic, but i could be great if could
inform me that TMP is full and exit to console.

This is actually a bug that goes across qemu and the kernel:

It's unfortunately not very simple to work around. When the libvirt
back end is working we'll be able to handle this case better.
