[Libguestfs] supermin-helper: ext2: parent directory not found: /mnt/bigdata/var: File not found by ext2_lookup

Mon Nov 25 16:32:23 UTC 2013

Hello,

I've found a problem running libguestfs on my system.

The system has /var mounted with a symbolic link to /mnt/bigdata/var

root at red1:/var/log/nova# ls -ld /mnt/bigdata/var
drwxrwxr-x 15 root users 4096 jul  7 17:55 /mnt/bigdata/var
root at red1:/var/log/nova# ls -ld /var
lrwxrwxrwx 1 root root 16 oct 30  2012 /var -> /mnt/bigdata/var

Any help here?

this is test tool output:

libguestfs-test-tool
