hey everyone,
had quick question on logical volumes , such ubuntu. i've been looking setting storage array of 4 2tb hard drives media storage in house have ran wall with sort of array should use, whether setting full raid system (raid 5 or 10 likely) or using lvm stripping. 1 thing lvm however, there no parity or redundancy built in case 1 hard drive fails. wondering if possible create similar of lvm stripping, instead logical volume sorted whole individual files, not stripping them across array. way, if 1 drive fails, sure, lose contents of 1 drive, rest of content isn't lost , have no loss of space because there no inherent parity.
input appreciated
thanks

the traditional way suggest use raid instead of or in addition lvm. (if in addition to, you'd set raid , use lvm on raid volume(s) create.)
might consider looking @ -m (--mirrors) option lvcreate, though. i've never used option, based on man page description, sounds sets equivalent of raid 1 mirror.
