The calculate_snapsize function calculates using the number of free extents, but the --size option for lvcreate seems to want a size in bytes (or m or g)
I think if you do something like

my $extent_size = $parts[12];
my $free_extents  = $parts[15];
...
$self->{snapsize} = $extent_size * $free_extents . "k"
#append k because default is megabytes

Also when I set
property "SNAPSHOT-SIZE" "1000"
in my dumptype it doesnt seem to affect the size of the actual snapshot

I've currently got the value hardcoded in the lvcreate line.

The 'action' argument has been removed from recent versions of print_to_server_and_die(). Your script can be fixed by removing the first empty-string argument to print_to_server_and_die().

Hello,

First of all... Greate Job!

But I have small problem... I can't backup not mounted file system.
Problem is in amgtar software... they need to calculate estimate but it try to do on /dev/vg0/some-lvm
Ther is any option to give back to amgtar temporary location in /tmp of mounted LVM ?

Thanks in advanced!

I have two perl programs installed on the client side - a original perl from Linux distribution which is x86_64 in /usr/bin; a compiled perl from source which is i386 in /usr/local/bin. I changed the amlvm-snapshot program to just include /usr/bin in PATH but still not successful. I can't see the problem from above debug files.

$ENV{'PATH'} = "/sbin:/usr/sbin:/usr/bin";

Client host is CentOS 5
