How to handle remove media (was: Re: What about not warn on some abort_transaction() case whose reason is known?)

I am cc´ing this to fsdevel as I think how to handle a disconnected usb device may be of broader interest. Well free to drop Cc again in case you see it as only BTRFS specific issue. Am Mittwoch, 31. Dezember 2014, 09:30:49 schrieb Qu Wenruo: Hi all, Hi Qu, While surfing the Redhat BZ, a

Phillip I had a similar question a year or two ago ( specifically about raid10 ) so I both experimented and read the code myself to find out. I was disappointed to find that it won't do raid10 on 3 disks since the chunk metadata describes raid10 as a stripe layered on top of a mirror.
