https://bugzilla.redhat.com/show_bug.cgi?id=1025230 When determining whether a FS pool is mounted, rather than assuming that the FS pool is mounted just because the target.path is in the mount list, let's make sure that the FS pool source matches what is mounted Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- src/storage/storage_backend_fs.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/storage/storage_backend_fs.c b/src/storage/storage_backend_fs.c index 1dd5727..70e6be6 100644 --- a/src/storage/storage_backend_fs.c +++ b/src/storage/storage_backend_fs.c @@ -419,6 +419,7 @@ static int virStorageBackendFileSystemIsMounted(virStoragePoolObjPtr pool) { int ret = -1; + char *src = NULL; FILE *mtab; struct mntent ent; char buf[1024]; @@ -431,16 +432,23 @@ virStorageBackendFileSystemIsMounted(virStoragePoolObjPtr pool) } while ((getmntent_r(mtab, &ent, buf, sizeof(buf))) != NULL) { - if (STREQ(ent.mnt_dir, pool->def->target.path)) { + if (!(src = virStorageBackendFileSystemGetPoolSource(pool))) + goto cleanup; + + if (STREQ(ent.mnt_dir, pool->def->target.path) && + STREQ(ent.mnt_fsname, src)) { ret = 1; goto cleanup; } + + VIR_FREE(src); } ret = 0; cleanup: VIR_FORCE_FCLOSE(mtab); + VIR_FREE(src); return ret; }
