It was noticed that when you have zvols in multiple datasets not all of the zvol devices are created at module load time. Fajarnugraha did the leg work to identify that the root cause of this bug is a non-zero return value from zvol_create_minors_cb(). Returning a non-zero value from the dmu_objset_find_spa() callback function results in aborting processing the remaining children in a dataset. Since we want to ensure that the callback in run on all children regardless of error simply unconditionally return zero from the zvol_create_minors_cb(). This callback function is solely used for this purpose so surpressing the error is safe. Closes #96
Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
