RN214 btrfs corruption forced readonly
Hi I have an RN 214 that I could not write to any more. I have seen other have simular issues on the forum. Need suggestion how to proseed. The problem started earlier today. I updated the ReadyNAS OS to version 6.8.1 just a few days ago. Not jsure if it is related. I have enabled Bit-rot-protection on the share, I read that this may be a bad idea? Log where the problem started: Oct 10 06:01:23 nas32-2017 kernel: ------------[ cut here ]------------ Oct 10 06:01:23 nas32-2017 kernel: WARNING: CPU: 1 PID: 32658 at fs/btrfs/disk-io.c:541 btree_csum_one_bio+0x108/0x10c() Oct 10 06:01:23 nas32-2017 kernel: Modules linked in: vpd(PO) Oct 10 06:01:23 nas32-2017 kernel: CPU: 1 PID: 32658 Comm: kworker/u8:1 Tainted: P O 4.4.88.alpine.1 #1 Oct 10 06:01:23 nas32-2017 kernel: Hardware name: Annapurna Labs Alpine Oct 10 06:01:23 nas32-2017 kernel: Workqueue: btrfs-worker btrfs_worker_helper Oct 10 06:01:23 nas32-2017 kernel: [<c0015980>] (unwind_backtrace) from [<c0012388>] (show_stack+0x10/0x14) Oct 10 06:01:23 nas32-2017 kernel: ------------[ cut here ]------------ Oct 10 06:01:23 nas32-2017 kernel: WARNING: CPU: 3 PID: 32525 at fs/btrfs/disk-io.c:541 btree_csum_one_bio+0x108/0x10c() Oct 10 06:01:23 nas32-2017 kernel: Modules linked in: vpd(PO) Oct 10 06:01:23 nas32-2017 kernel: [<c0012388>] (show_stack) from [<c039bcd0>] (dump_stack+0x94/0xa8) Oct 10 06:01:23 nas32-2017 kernel: [<c039bcd0>] (dump_stack) from [<c0020074>] (warn_slowpath_common+0x84/0xb4) Oct 10 06:01:23 nas32-2017 kernel: [<c0020074>] (warn_slowpath_common) from [<c0020140>] (warn_slowpath_null+0x1c/0x24) Oct 10 06:01:23 nas32-2017 kernel: [<c0020140>] (warn_slowpath_null) from [<c02a82b4>] (btree_csum_one_bio+0x108/0x10c) Oct 10 06:01:23 nas32-2017 kernel: [<c02a82b4>] (btree_csum_one_bio) from [<c02a7170>] (run_one_async_start+0x34/0x44) Oct 10 06:01:23 nas32-2017 kernel: [<c02a7170>] (run_one_async_start) from [<c02e90fc>] (normal_work_helper+0x108/0x1f4) Oct 10 06:01:23 nas32-2017 kernel: [<c02e90fc>] (normal_work_helper) from [<c0035338>] (process_one_work+0x134/0x344) Oct 10 06:01:23 nas32-2017 kernel: [<c0035338>] (process_one_work) from [<c0035594>] (worker_thread+0x4c/0x4bc) Oct 10 06:01:23 nas32-2017 kernel: [<c0035594>] (worker_thread) from [<c003a858>] (kthread+0xfc/0x114) Oct 10 06:01:23 nas32-2017 kernel: [<c003a858>] (kthread) from [<c000f368>] (ret_from_fork+0x14/0x2c) Oct 10 06:01:23 nas32-2017 kernel: ---[ end trace 5d7482ac13d21d10 ]--- Oct 10 06:01:23 nas32-2017 kernel: CPU: 3 PID: 32525 Comm: kworker/u8:6 Tainted: P O 4.4.88.alpine.1 #1 Oct 10 06:01:23 nas32-2017 kernel: Hardware name: Annapurna Labs Alpine Oct 10 06:01:23 nas32-2017 kernel: Workqueue: btrfs-worker btrfs_worker_helper Oct 10 06:01:23 nas32-2017 kernel: [<c0015980>] (unwind_backtrace) from [<c0012388>] (show_stack+0x10/0x14) Oct 10 06:01:23 nas32-2017 kernel: [<c0012388>] (show_stack) from [<c039bcd0>] (dump_stack+0x94/0xa8) Oct 10 06:01:23 nas32-2017 kernel: [<c039bcd0>] (dump_stack) from [<c0020074>] (warn_slowpath_common+0x84/0xb4) Oct 10 06:01:23 nas32-2017 kernel: [<c0020074>] (warn_slowpath_common) from [<c0020140>] (warn_slowpath_null+0x1c/0x24) Oct 10 06:01:23 nas32-2017 kernel: [<c0020140>] (warn_slowpath_null) from [<c02a82b4>] (btree_csum_one_bio+0x108/0x10c) Oct 10 06:01:23 nas32-2017 kernel: [<c02a82b4>] (btree_csum_one_bio) from [<c02a7170>] (run_one_async_start+0x34/0x44) Oct 10 06:01:23 nas32-2017 kernel: [<c02a7170>] (run_one_async_start) from [<c02e90fc>] (normal_work_helper+0x108/0x1f4) Oct 10 06:01:23 nas32-2017 kernel: [<c02e90fc>] (normal_work_helper) from [<c0035338>] (process_one_work+0x134/0x344) Oct 10 06:01:23 nas32-2017 kernel: [<c0035338>] (process_one_work) from [<c0035594>] (worker_thread+0x4c/0x4bc) Oct 10 06:01:23 nas32-2017 kernel: [<c0035594>] (worker_thread) from [<c003a858>] (kthread+0xfc/0x114) Oct 10 06:01:23 nas32-2017 kernel: [<c003a858>] (kthread) from [<c000f368>] (ret_from_fork+0x14/0x2c) Oct 10 06:01:23 nas32-2017 kernel: ---[ end trace 5d7482ac13d21d11 ]--- ....

Bitlocker locked? Not looking good, ALL my data!
So my LUN Volume has been working great with iSCSI initiators on windows 8.1 and now 10. No problem. Today, after upgrading my Surface Pro 3 to win 10,. I create a new initiator on the admin page for ReadyNAS, connect with the iSCSI initiator. and it connected, but right away had a exclamation mark thing over the drive letter in explorer for each drive. It was lagging bad and would keep giving (not responding) message in explorer. After a few mins I disconnected the initiator from the target and moved back to my main desktop PC. I reconnected on that PC like I normally have been, and now all of the drives are showing that exclamation point icon, and the drive that I was actually trying to access from the surface P3 is showing as bitlocker locked. If I try to open any of the drives in explorer, it says disk corruption or damaged. This is really freaaking me out being that this is literally all of my data and I am new to NAS so I was thinking that being that I had RAID 5 I was safe. It never occuired to me that I would lose 4 HDDs at once. Is there anything I can do or am I totally boned here? Please help and thank you in advance for ANY help.5.5KViews0likes9Comments
