Is there any concern with mixing 4KB-sector drives with 512-byte sector drives in the same LV?Both LVM2 and Device Mapper have been updated to accommodate stacking such a mix of drives. See this for a bit more detail: http://people.redhat.com/msnitzer/docs/io-limits.txt Particularly, the "Stacking I/O Limits" section. The concern raised for partial (4k) writes to the 512b drive was discussed a bit more here: http://lkml.org/lkml/2010/2/22/295
Are there any version-level hints about when/where these changes appear and come together in the real world (i.e. distributions like RHEL, debian, Ubuntu)?
