Information

Directory attributes in Parallels Cloud Storage syntax changed:
1. max-local-replicas changed to max-host-replicas
This attribute specifies how many replicas of the same chunk can be allocated on the same host regardless of number of CS service instances running on it.
Note, hosts are distinguished by unique host identified stored at /etc/pstorage/host_id

2. New client-ssd-cache attribute added
This attribute sets whether data should be put to SSD cache or not

Example:
[root@pcs6 ~]# pstorage -c mycluster get-attr /pstorage/mycluster/
connected to MDS#1
Path: 'pstorage://mycluster/'
Attributes:
client-ssd-cache=1
replicas=1:1
locality=3
tier=0
max-host-replicas=1
chunk-size=67108864


Description of these parameters find in Parallels Cloud Storage Administration Guide.
Also more help is available in man page:
