Hello everybody, recently (today) I had a problem. I'm trying to create a HA Cluster for a DCE server. This is difficult work and sometimes very confusing. My goal is to make it bootable from a SAN. So far I managed to install GRUB and boot the machine. The rootfs and the rest can be mounted. I found, then, that the SCSI-devices inside one of my volume groups were the wrong ones. What is special about that is that the same content on a device can be seen on different SCSI-devices. This is due to some mirroring within the storage sytems. I cannot avoid that. Now, I have a readonly physical volume inside one of my volume groups. I want to insert the writeable mirror and get rid of the readonly. AFAICS this is not possible because I cannot force vgscan to insert a specified SCSI-device. Of course the VGDA is marked "part of VG xxx" and cannot be written anymore. So it cannot be imported nor exported or added to a new VG. Maybe there is an option anywhere how to scan a particular device. Does anybody know how to trick LVM? Is there a hexeditor to patch the VGDA backups to use different /dev/sdXX devices? And if so, does that help? I'm using redhat 8.0 and I'm bound to that version.
