Re: [Ginger-dev-list] Storage related tasks for future gingerreleases

We can do that by having the partition that's used by consumers (e.g. storage pools used by VMs) listed in some sorta sqlite db file. This way all the destructive operations on that partition can query that sqlite file and know if there are any consumers and take appropriate operations.

I agree with them all, considering of course that features such as delete a partition from the disk should be developed with EXTREME caution. heheheh

Hi,

 

Now that we are going to have a dedicated host management plugin (Ginger), I was thinking about what storage related things a plugin like this could be able to do. 

 

I have listed some of the things that came to my mind. Let me know if you think ginger should be doing these kinds of things related to storage in future. 

 

 

 

Disk partitioning (fdisk) - 
   1. View partition table 
   2. Create/delete/modify a partition on the disk

File systems - 
   1. Display file system related information per block device/paritition
   2. File system related operations (whichever are applicable for the given filesystem) - 
       a. Create a file system
       b. Mount/unmount a file system
       c. Resize a file system
       d. quota managemenent 
       e. backup/restore 
       f. repair (fsck)
   3. Filesystems to support - ext3, ext4, xfs
   4. GPFS as a cluster filesystem

swap -
   1. add/remove/list swap
Fiber channel (FCP) attached storage - 
   1. activate/deativate a LUN presented to the given host
   2. Scan and initialize LUNs
ECKD DASD (System z) -
   1. Interact with CSS to enable/disable ECKD DASD devices
   2. Format a ECKD DASD storage so that they can act like block storage
    3. List ECKD DASD devices 

LVM - 
   1. Physical Volumes (pv) - 
       a. Scan and list block devices 
       b. Resize a pv
   2. Volume groups (vg) - 
       a. Add/remove a pv from vg
       b. List existing vgs
       c. activate/deactivate a vg
       d. split/combine/backup/migrate a vg
       e. create/delete/modify/list a vg
   3. Logical Volume (lv) -
       a. Create/delete/modify/list a lv
       c. Create/delete/merge/list snapshot of a lv
       d. RAID support - 1/4/5/6/10
