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?
As Michal suggested in your previous mail, cscope is a good choice for
you to learn libvirt. E.g. If you looked at the public API for volWipe in
src/libvirt.c, and using cscope like:
cs find s volWipe
You will get where it's implemented.
Could anyone please give me some suggestions? Thanks in advance.
However, if users just want to wipe portions data of this volume, which
command(interface) of libvirt could finish?
