(Updated Jan. 8, 2013, 12:09 p.m.) Review request for cloudstack and anthony xu. Changes ------- updating the patch. Summary (updated) ----------------- CLOUDSTACK-356 Snapshot errors with multiple secondary storage in one zone. Description ------- Fixed CLOUDSTACK-356 The issue is happening because of the multiple secondary storages, the secondary storage which is used first is getting mounted on the host resulting in failure of other snapshot using different secondary storage as it is not getting mounted on the host. For eg: 1. When first incremental snapshot (eg Ssec1-1) is taken, secondary storage (sec1) is mounted on local path “/var/run/sr-mount/ on the host. 2. Second incremental snapshot (Ssec1-2) is created, to get the parent vhd, the secondary storage is mounted at mount path “/var/run/cloud_mount/dc_id/snapshots”. 3. If other snapshot (for different volume) is created on different secondary storage (sec2), sec2 is not getting mounted on "/var/run/cloud_mount/dc_id/snapshots" path. The fix is to mount other secondary storages as well on the host. The local mount path in vmopsSnapshot.py is modified, instead of mounting on “/var/run/cloud_mount/dc_id/snapshots”, “/var/run/cloud_mount/dc_id/snapshots/secHostid” mount path is used. This addresses bug CLOUDSTACK-356.

Snapshot Creation: Host 1 has a vm i-1, volume ROOT-1 DATA-1, Host 2 has a vm i-2, volume ROOT-2 DATA-2, Taken recurring snapshot for 4 volumes. Verified: multiple secondary storages are getting mounted on host. Snapshots creation successful 2. Template Creation: Verified: templates successfully created from the above snapshots 3. Volume creation: Verified: volumes successfully created from the above snapshots 4. VM Migration Migrate i-1 from Host-1 to Host-2. Verified: Secondary mount point successfully created on Host-2.
