Hi all,
I am not very clear about the usage of ‘virsh vol-wipe vol_name’. I think
if 'virsh vol-wipe vol_name' can just wipe all the datas in this volume and
it is similar as we format a volume which the datas would be wiped, right?
After this wipe, we can use this volume like a new one.
After i read the back-end storage drivers for libvirt, i cannot find any storage
driver like following
128 VIR_STORAGE_POOL_DIR, /* Local directory */
129 VIR_STORAGE_POOL_FS, /* Local filesystem */
130 VIR_STORAGE_POOL_NETFS, /* Networked filesystem - eg NFS, GFS, etc */
131 VIR_STORAGE_POOL_LOGICAL, /* Logical volume groups / volumes */
132 VIR_STORAGE_POOL_DISK, /* Disk partitions */
133 VIR_STORAGE_POOL_ISCSI, /* iSCSI targets */
134 VIR_STORAGE_POOL_SCSI, /* SCSI HBA */
135 VIR_STORAGE_POOL_MPATH, /* Multipath devices */
136 VIR_STORAGE_POOL_RBD, /* RADOS Block Device */
137 VIR_STORAGE_POOL_SHEEPDOG, /* Sheepdog device */
has realized storageVolumeWipe feature. So how could we test this feature?
Could anyone please give me some suggestions? Thanks in advance.
As Michal suggested in your previous mails, you *should* use cscope.
If you looked at the public API, and using cscope like:
cs find s volWipe
You will find where it's implemented.
However, if users just want to wipe portions data of this volume, which
command(interface) of libvirt could finish?
