Hi,  
We have two nodes percona xtradb cluster with one arbiter.

We have configured in my.cnf with this settings:

[xtrabackup]  
compress  
parallel=6

When cluster transfer SST, only transfer in one thread and not in 6.

Server version: 5.6.21-70.1-56-log Percona XtraDB Cluster (GPL), Release rel70.1, Revision 938, WSREP version 25.8, wsrep\_25.8.r4150

Anybody with this behavior?

Best regards.

Can you please share mysql error log from donor and joiner and along with that backup log to check further. Also, what version of Xtrabackup you are using ?

$ xtrabackup --version

HI Mirfan,

Thanks for your help

xtrabackup version is the same on the two nodes:

```auto
xtrabackup version 2.2.12 based on MySQL server 5.6.24 Linux (x86_64) (revision id: 8726828)

```
