Hello, after searching the web for a while i now bother you with my wish. ;-) Well i use LVM now already for nearly 2 years and had in this time 2 big problems (some harddisks gave up) where i lost nearly everything. I tried to restore the LVM and filesystem but well if you lose 1/4 of your LVM its really hopeless (or maybe I just didnt know how ;-P coz the howto's to this question where well not very helpfull). What i would like is a solution which is between LVM and a RAIDx. LVM has in my eyes the disadvantage that you create a filesystem over different drives/partitions. If you lose one you nearly lose everything. With a RAID you lose a harddrive/partition (diskspace) to build it (more costs for harddrives and maybe a controller). The solution between would be that all drives still have their own 'filesystem'. The logical unit would just need to spread the directories/files over the allocated drives/partitions and keep on at least 2 drives something like a index (maybe just one file like ext3 is using it) file where the dirs have to go logicaly if you browse through the logical unit. If one drive would fail you would have still the rest. Some directories would be maybe missed but well at least the rest would still be accessable. If there would be a chronical component in combination with a smaller raid all newer files could first pass on the raid and then went onto a unsecure part of the logial volume (not LVM). A scheduler could relocate all dirs at some times so that all drives have the same level of usage (diskspace). Well, because i am not a programmer i am passing this idea to you readers. Maybe somebody has already programmed something like that, then please let me know. If not maybe somebody wants to. I guess it shouldnt be sooo difficult. Anyways, let me know if possible. Maybe i can give some more ideas or explain it better. Thanks for reading. :-) OJ _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
