Subject: Spare volumes and hot auto-replacement feature
Date: Thu, 5 May 2016 01:18:15 +0200 [thread overview]
Message-ID: <572A8337.1030505@mail.ru> (raw)
Dear btrfs community,
I am interested in spare volumes and hot auto-replacement feature [1]. I have a couple of questions:
* Which kernel version this feature will be included?
* The description says that replacement happens automatically when there is any write failed or flush failed. Is it possible to control the ratio / number of such failures? (e.g. in case it was one-time accidental failure)
* What happens if spare device is smaller then the (failing) device to be replaced?
* What happens if during the replacement the spare device fails (write error)?
* Is it possible for root to be notified in case if drive replacement (successful or unsuccessful) took place? Actually this question is actual for me for overall write/flush failures on btrfs volume (btrfs monitor).
Many thanks!
