(unable to find logical $hugenum len 4096) Message-Id: <79471CD1-CDDD-4EDD-B255-40568B8446E2@nickle.es> Date: Thu, 22 Aug 2013 02:47:38 -0400 To: linux-btrfs@vger.kernel.org Mime-Version: 1.0 (Mac OS X Mail 6.5 \(1508\)) Sender: linux-btrfs-owner@vger.kernel.org List-ID: Hi list! I recently butchered my filesystem, and I was wondering if anyone knows how to help. Problem: My filesystem is screwed up, and I can't mount it at all right now. In the logs, the problem begins around 45s. Background: I'm running a 6x4TB RAID5 array using md. I have a few virtual machines using said array, and one of them is a btrfs storage server. I ran into some issues where FS errors would cause the host system to enter a read-only state, which led to the corruption of the guest's file system. Adding insult to injury, this occurred right as I began the initial backup to another system with rsync. :( What I've done so far: I've made a few attempts to mount the partition in read-only recovery mode to no avail. I created another virtual disk and installed ArchBang to use as a recovery environment. I also tried running find-root, but I got no console output after two days of it running, and it just sat there burning CPU time. I would be seriously grateful to anyone that can figure out a way to mount/fix this partition, and I'd be willing to send some bitcoin over to anyone that can help me get partition mounted and/or repaired! dmesg's output: [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 3.9.8-1-ARCH (tobias@testing-i686) (gcc version 4.8.1 (GCC) ) #1 SMP PREEMPT Fri Jun 28 07:43:59 CEST 2013 [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000007fffdfff] usable [ 0.000000] BIOS-e820: [mem 0x000000007fffe000-0x000000007fffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000feffc000-0x00000000feffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fffc0000-0x00000000ffffffff] reserved [ 0.000000] Notice: NX (Execute Disable) protection cannot be enabled: non-PAE kernel!
