           Summary: xendomains stop does not check for free space before
                    stopping
           Product: Xen
           Version: unstable
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: henning_sprang@xxxxxx


I just note that down from somebody who mailed it to the users list and did not
test the solution myself yet.

(see http://lists.xensource.com/archives/html/xen-users/2007-01/msg00721.html)

The xendomains script seems not to check if there is enough free spce to save a
domain when runninng xendomains stop.

This results in 100% filled /var directory, and broken snapshots.

A proposed solution is, adding the following lines to xendomains:


if test -n "$XENDOMAINS_SAVE"; then
                    echo -n "(save)"
## save domain if enough free disk space
free=`df -k $XENDOMAINS_SAVE | awk '{print $4}'`
size=`xm list | grep $name | awk '{print $3}'`
sizeplus=$(($size*11/10))       ## size + 10%
[ $free -lt $size ] && continue
