since we have the option1 done, why continue with raid1 code? could we port write-behind to raid10 code? another thing, could raid10 work without replica? like a raid0? why? just to remove many files with the same function (raid1and raid0, if raid10 do the same work, many some mdadm changes allow us to --level=1 to understand that's raid10 without stripe, --level=0 is raid10 without mirrors) 2011/2/16 Roberto Spadim <roberto@xxxxxxxxxxxxx>: > hummm nice =) > near layout is the key for many mirrors? > i will check more layouts > > 2011/2/16 Robin Hill <robin@xxxxxxxxxxxxxxx>: >> On Wed Feb 16, 2011 at 10:40:40AM -0300, Roberto Spadim wrote: >> >>> i agree with giovanni, another question since we will make a lot of >>> change on mirrors based arrays (raid1, raid10) with the badblock list, >>> could we: >>> >>> option1) remove raid1 code, change raid10 to work without raid0 >>> 'service', change raid10 to work with more than 1mirror (like raid1 >>> do)? >>> option2) port raid10 layout to raid1? >>> >> You can already do option1 (if I'm understanding you correctly).
