Hello all,
Another option is to call ploop balloon discard directly.
>From 'man ploop':
balloon discard
In a situation when a lot of disk space were freed on an in-ploop
filesystem, use ploop balloon discard to optimize the ploop image size.
ploop balloon discard [--automount] [--to-free size] [--min-block
min_size] [--defrag] DiskDescriptor.xml
Iteratively try to relocate and discard unused blocks from a ploop
image, reducing its size.
Note that ploop device and its inner file system should be mounted. If
not, one can use --automount option to automatically mount ploop for the
duration
of the operation.
Option --defrag can be used to run a filesystem defragmentation utility
(currently e4defrag2 on ext4 only) before the main operation.
Option --to-free can be used to specify a maximum disk space to be
freed. In other words, stop the process once freed space exceeded requested
size.
Default is 0, meaning to try to free as much space as possible.
Option --min-block can be used to specify a minimum size of an extent
to free. The smallest possible extent is 1 cluster (currently 1 MB), one can
spec‐
ify higher value to speed up the whole discarding operation.
Note that the same functionality is available by means of vzctl compact
command.
Best regards,
Konstantin
