Hi, I am writing a pseudo (filter) driver over SCSI disk driver (sd). There would be corresponding pseudo devices created. These devices would in turn access SCSI disk (thorugh sd) with some added functionality. I want to use these pseudo device withe Linux LVM. But when I tried pvcreate on such a device, the reponse was "invalid physical volume". Tracing the source code showed that lvm_get_device_type does not recognize the pseudo device as of a valid device type. In fact, valid device types have been specified in a structure defined inside the function itself. I used LVM version 1.0.3 as my platform is Red Hat Linux 7.x. Wanted to know which LVM version recognizes such pseudo devices. Need some help to make my pseudo driver work with LVM. Thanks and Regards, Bharavi Oak. _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
