Environment

SUSE Enterprise Storage 6

Situation

Running DeepSea stage 2 results in the following example exception:

sre_constants.error: bad character range 2-1 at position 9
 

Resolution

Edit the "/srv/pillar/ceph/proposals/policy.cfg" file and use valid globbing to target minions or target minions individually without the use of globbing.

Cause

Invalid globbing is being used to target minions in the "/srv/pillar/ceph/proposals/policy.cfg" file.

Additional Information

The error is related to how DeepSea handles globbing, for the example provided above the problem entries in the policy.cfg file were the storage minions, excerpt of the problematic entry:
 
#STORAGE
role-storage/cluster/node[2-18]*.sls

Specifying something like [2-18] as per the above is not interpreted as any number between 2 and 18 as would be expected, it's interpreted as the character range 2-1 which is invalid, because it's backwards (hence the exception), plus the character 8.

For the above example, one possible solution while still using globbing is to specify the minions as follows instead:
 
role-storage/cluster/node[2-9]*.sls
role-storage/cluster/node1[0-8]*.sls
