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.
Actually, i can find volWipe itself. Let me find deeply. -- Thanks Harry Wei
