Re: [Libvirt-cim] [PATCH] [TEST] #3 Adding new tc to verify fs storage pool creation

# HG changeset patch # User Deepti B. Kalakeri&lt;deeptik(a)linux.vnet.ibm.com&gt; # Date 1246370002 25200 # Node ID 479f287a17fd08e4e22ac37459393f6f8327315a # Parent fe9471d9dd3372b673da5596a18cc49e553b13fa [TEST] #3 Adding new tc to verify fs storage pool creation. Updates in patch 3: ------------------- 1) Used the pre_check from XenKvmLib.common_util 2) imported PASS /FAIL from CimTest.ReturnCodes 3) Modified the verify_pool() 4) Modified the clean_up() 5) Addressed some minor typos Update in patch 2: ------------------ 1) rearranged import stmst 2) add check to see if cimserver is started 3) Added options to clean the old log 4) Added options to get the debug msg on the stdout 5) Added lxc support 6) Moved the looping for setting the poolsettings in a function 7) Rectified the virt_type to virt and also to use KVM for checking while setting vuri Patch 1: -------- This tc will not be run in the batch mode of cimtest and hence needs to be run individually using the command below. python create_verify_storagepool.py -t 2 -d /dev/sda4 -m /tmp/mnt -n diskfs -v Xen -u <username> -p <passwd> Tested with Xen on RHEL with current sources for fs type pool. Will Update the patch to include logical pool verification as well. Signed-off-by: Deepti B.
