hummm, wow very new informations to me... today linux don't have a generic badblock remap?! that's what i understood? for example... ext2,3,4,xfs,reiserfs,zfs, and others fs, they handle badblock by their self? right? it's a nice information i never thinked about a layer only for badblock reallocation, i read/write in this list of linux-raid when the started the badblock development, in some time near to raid1 write multithread today the badblock of raid1 is embedded in the source? or it's easy to implement a new layer just to badblock realloc logic? about "mkswap -c" it just show information like you told, i'm a bit surprised about no badblock at swap that's information is new to me i will read about others os (freebsd, reactos, etc) to check how they handle this there I'm rethinking now about the swap as a file in a filesystem, this could increase security or another solution is better? -- 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
