[libvirt] [PATCH] virsh: More friendly err if no pool is specified for looking up a vol

There are 3 ways to lookup a volume, only virStorageVolLookupByName needs pool object. So if no --pool is specified, it will tries to get the volume via virStorageVolLookupByPath/virStorageVolLookupByKey. But if all 3 ways fails, and no --pool is specified, a friendly error might help the user get right way quickly. --- tools/virsh.c | 9 +++++++-- 1 files changed, 7 insertions(+), 2 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index 371346a..4b9e662 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -14714,8 +14714,13 @@ vshCommandOptVolBy(vshControl *ctl, const vshCmd *cmd, vol = virStorageVolLookupByPath(ctl->conn, n); } - if (!vol) - vshError(ctl, _("failed to get vol '%s'"), n); + if (!vol) { + if (pool) + vshError(ctl, _("failed to get vol '%s'"), n); + else + vshError(ctl, _("failed to get vol '%s', specifying --pool " + "might help"), n); + } if (pool) virStoragePoolFree(pool); -- 1.7.6
