<font size="-1"><font face="Courier 10 Pitch">Hi everybody.<br>
<br>
I have two peers in the cluster and a 2-replica volume which
seems okey if it was not for one weird bit - when a peer reboots
then on that peer after a reboot I see:<br>
<br>
$ gluster volume status USERs <br>
Status of volume: USERs<br>
Gluster process TCP Port RDMA Port

Task Status of Volume USERs<br>
------------------------------------------------------------------------------<br>
There are no active volume tasks<br>
<br>
I do not suppose it's expected.<br>
On such rebooted node I see:<br>
$ systemctl status -l glusterd<br>
