student@ceph1:~$ nusactl start cpadm-002-1


Instructions

Note: Execute on pod-<username>-ceph1 node

1. Create pool and create object. 

su - ceph-adm

# Create pool
sudo ceph osd pool create pool-test 128  
# Intialize pool
sudo rbd pool init pool-test  
echo test > filetest1.txt

# Create object data
sudo rados put object-test1 filetest1.txt --pool=pool-test


2. Download & Copy content of pool.

# Delete filetest1.txt
rm filetest1.txt 
# Fetch object
sudo rados get object-test1 filetest1.txt --pool=pool-test 

# Create pool for testing copy content of a pool
sudo ceph osd pool create pool-test-copy 128 
sudo rbd pool init pool-test-copy
# Copy content of a pool
sudo rados cppool pool-test pool-test-copy


3. Verify the pool. 

sudo rados ls --pool=pool-test
sudo rados ls --pool=pool-test-copy

# Remove Object
sudo rados rm object-test1 --pool=pool-test 
sudo rados ls --pool=pool-test
sudo rados ls --pool=pool-test-copy


4. Delete pool.

# Configuration to allow deleting pool
sudo ceph config show mon.pod-<username>-ceph1 | grep mon_allow_pool_delete 
sudo ceph tell mon.pod-<username>-ceph1 injectargs --mon-allow-pool-delete=true
sudo ceph config show mon.pod-<username>-ceph1 | grep mon_allow_pool_delete
sudo ceph osd pool delete pool-test pool-test  --yes-i-really-really-mean-it
