xtrabackup IST SST: Can't find nc in the path

[P4tt4nz]

Hi Gurus

Seems that i have problems with xtrabackup IST and SST again on a new cluster.

I try to start up a cluster nod that i know need a IST. I have edit the grastat file so it should start at the right position. Xtrabackup installed and works if i give the PATH to the xtrabackup and server bins.

The ip of the node that fails: 172.27.8.196.
The paths in the error log below seems to be right.

This is part of the log on the node that fails to start:

No log on the other node (theres 2 and the other i a garbd).

I have inserted this into the wsrep_sst_xtrabackup file on both nodes so it can find the xtrabackup bins:
PATH=$PATH:/db/tools/xtrabackup/bin

Here is the wsrep variables in the failing nodes my.cnf:
wsrep_sst_method                      = xtrabackup
wsrep_cluster_name                    = aclutst_cluster
innodb_locks_unsafe_for_binlog        = 1
wsrep_node_name                       = aclutst3
wsrep_cluster_address                 = gcomm://172.27.8.170,172.27.8.171
wsrep_provider_options                = 'ist.recv_addr=172.27.8.196;gcache.size=100M;'
wsrep_sst_auth                        = root:
wsrep_sst_donor                       = aclutst2

I appreciate and look forward to some help as im stuck
