I know, there is a linux-raid-ML ;-) I unsubscribed there a few months ago.
What I would like to discuss and ask here: Is it problematic to have both 512-byte- and 4k-sector-drives in one RAID array? I have that case at a customer where the partition map was copied over (sfdisk -d) from an old to a new drive. Now we have misaligned raid member drive with 4k and the older member with 512bytes. Additional question here: which version to use? 0.90 for booting, right? As far as I understand the manpage the "-e" switch does not have much to do with aligning or so. - I plan to add another new 4k drive to the RAID1 array after partitioning it correctly aligned. Then let it sync, remove other disk ... partition correctly ... etc etc Stefan
