Hello there, I have a 3 disk btrfs RAID 1 filesystem, with a single failed drive. Before I attempt any recovery I’d like to ask what is the recommended approach? (The wiki docs suggest consulting here before attempting recovery[1].)
The system is powered down currently and a replacement drive is being delivered soon. Should I use “replace”, or “add” and “delete”? Once replaced should I rebalance and/or scrub? I believe that the recovery may involve mounting in degraded mode. If I do this, how do I later get out of degraded mode, or if it’s automatic how do i determine when I’m out of degraded mode? The system is running Ubuntu 16.04 LTS with kernel 4.4.0. 1: “it may be helpful to consult the mailing list of irc channel before attempting recovery”. - https://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices#Replacing_failed_devices -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
