Re: [libvirt] [PATCH] Add APIs for obtaining the unique ID of LVM & SCSI volumes

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Both LVM volumes and SCSI LUNs have a globally unique identifier associated with them. It is useful to be able to query this identifier to then perform disk locking, rather than try to figure out a stable pathname. --- src/util/storage_file.c | 93 +++++++++++++++++++++++++++++++++++++++++++++++++ src/util/storage_file.h | 3 ++ 2 files changed, 96 insertions(+) +#ifdef HAVE_UDEV +const char *virStorageFileGetSCSIKey(const char *path) +{ + char *key = NULL; + virCommandPtr cmd = virCommandNewArgList( + "/lib/udev/scsi_id",
