And it even would get funnier if the drive's relocation table could be accessed (no idea if this is possible): The LVM would notice if the drive has relocated an (LBA) block, move it out of the way (somewhere else in the LV) and then remove the relocation (never access that LBA block anymore). This way an slowly dying disk can be used for quite a long time. Think of boxes with very limited physical access (eg. outoor field systems) or huge archives w/ non-critical/regeneratable data (eg. media collections w/ originals available, mirrors, etc). The idea of using even old and damaged disks at really low costs (not counting the power consumption ;-P) is seems quite fascinating to me :) cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ --------------------------------------------------------------------- -- gentoo-user@lists.gentoo.org mailing list
