Hello Farkas, FL> that's realy a long avaiting feature. but at the same time wouldn't it FL> be finally possible to convert a non raid partition to an raid1? it's FL> avery common thing and they used to said it's even working on windows:-( That would be cooler than making a metadevice and copying tons of files :) However, AFAIK this would require some support on FS side as well? FS-addressable space in a RAID metadevice (i.e. submirror) is aligned till the pre-last 64K block. If the partition was used up completely, the last [64..128]Kb can be used by its data and need to be remapped to a free location. And this is quite FS-dependant (like grow/shrink) and should be addressed by those FS toolkits. tune2fs and e2fsck do some similar remapping job when we enable/disable spare superblocks on a used filesystem... -- Best regards, Jim Klimov mailto:klimov@xxxxxxxxxxx - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
