servername' on Debian 7.0¶

schoekek opened issue at 2013-03-26 14:05:¶

Hi,

I've the following problem on rear 1.14 in Debian 7.0 alias wheezy.
This ist the config:

BACKUP=NETFS
NETFS_URL=nfs://nfshost/backup
OUTPUT=ISO
BACKUP_PROG_EXCLUDE=( '/tmp/*' '/dev/shm/*' )

Here the output from rear mkbackup:
....

/tmp ist mounted:

tmpfs on /tmp type tmpfs (rw,nosuid,nodev,relatime,size=607120k)

any idea?

Can you manually mount the NFS server somewhere under your /tmp?

$ mkdir /tmp/rear-test
$ mount nfshost:/backup /tmp/rear-test

schoekek commented at 2013-03-26 14:25:¶

Yes, this is not the problem.
mkdir /tmp/rear-test mount -t nfs -o rw,noatime nfsserver:/backup /tmp/rear-test
The nfsserver:/backup is mounted...

gdha commented at 2013-03-26 15:00:¶

Ok, now try as user root touch /tmp/rear-test/myfile
If that fails then check on the NFS server if no_root_squash is setup correctly.
See http://www.centos.org/docs/4/4.5/Security_Guide/s2-server-nfs-noroot.html

Is this our first encounter with Debian 7?

Hi Karsten, nice to hear from you again. Will we see you at the LinuxTag?
