Fixed disk result in these pieces of information being cached. I think I've seen this very discussion before. It looks like kernel needs to distinguish things like removable media (truely removable - CDRoms etc) and some "dynamic" things like in this case (like with any raid array really), with iSCSI devices and so on. Currently, 'removable' is handy at detecting devices which should be handed to 'cdrom' or 'floppy' group (i think it was the cause of previous incarnation of this discussion). Right now, both ways are causing problems here or there. "Removable" is bad because it confuses "regular" linux tools, while !removable breaks configurability of arrays. /mjt - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
