Napalmd Posted June 19, 2020 Share #1 Posted June 19, 2020 (edited) Hi this happened yesterday and a reboot fixed the problem but today it didn't fix. Volume appears in crash mode, and read only mode. I logged in from ssh and looked at the logs, I saw this in dmesg after the reboot: Quote [ 58.067202] CPU: 0 PID: 11964 Comm: btrfs-cleaner Tainted: PF C O 3.10.105 #24922 [ 58.067203] Hardware name: Intel Corporation S3210SH/S3210SH, BIOS S3200X38.86B.00.00.0052.112920101508 11/29/2010 [ 58.067205] ffffffff814c5a5d ffffffff810355c6 ffff8800557e68b0 ffff8800379cfae8 [ 58.067207] 00000000fffffffb ffffffffa0ac8740 0000000000000419 ffffffff81035627 [ 58.067209] ffffffffa0acad48 ffff880000000020 ffff8800379cfaf8 ffff8800379cfab8 [ 58.067212] Call Trace: [ 58.067218] [<ffffffff814c5a5d>] ? dump_stack+0xc/0x15 [ 58.067221] [<ffffffff810355c6>] ? warn_slowpath_common+0x56/0x70 [ 58.067225] [<ffffffff81035627>] ? warn_slowpath_fmt+0x47/0x50 [ 58.067236] [<ffffffffa0a33ff5>] ? btrfs_del_csums+0x285/0x3c0 [btrfs] [ 58.067244] [<ffffffffa0a0ea7d>] ? __btrfs_abort_transaction+0xdd/0x130 [btrfs] [ 58.067254] [<ffffffffa0abd010>] ? add_to_free_space_tree+0xe0/0x100 [btrfs] [ 58.067264] [<ffffffffa0a23860>] ? __btrfs_free_extent+0xa70/0xd60 [btrfs] [ 58.067274] [<ffffffffa0a28bf3>] ? __btrfs_run_delayed_refs+0x443/0x11a0 [btrfs] [ 58.067284] [<ffffffffa0a2e473>] ? btrfs_run_delayed_refs+0xb3/0x2c0 [btrfs] [ 58.067294] [<ffffffffa0a2a510>] ? walk_up_tree+0xe0/0x200 [btrfs] [ 58.067304] [<ffffffffa0a40b8a>] ? btrfs_should_end_transaction+0x3a/0x60 [btrfs] [ 58.067314] [<ffffffffa0a2c4d0>] ? btrfs_drop_snapshot+0x390/0x950 [btrfs] [ 58.067326] [<ffffffffa0a53976>] ? btrfs_run_defrag_inodes+0x96/0x350 [btrfs] [ 58.067337] [<ffffffffa0a42888>] ? btrfs_clean_one_deleted_snapshot+0xb8/0x110 [btrfs] [ 58.067347] [<ffffffffa0a381c0>] ? cleaner_kthread+0x1f0/0x260 [btrfs] [ 58.067357] [<ffffffffa0a37fd0>] ? btree_invalidatepage+0x90/0x90 [btrfs] [ 58.067360] [<ffffffff81051f2f>] ? kthread+0xaf/0xc0 [ 58.067362] [<ffffffff81051e80>] ? kthread_create_on_node+0x110/0x110 [ 58.067365] [<ffffffff814ccc0d>] ? ret_from_fork+0x5d/0xb0 [ 58.067367] [<ffffffff81051e80>] ? kthread_create_on_node+0x110/0x110 [ 58.067368] ---[ end trace 27ae842d91e705b3 ]--- [ 58.067371] BTRFS: error (device dm-0) in add_to_free_space_tree:1049: errno=-5 IO failure [ 58.076599] BTRFS info (device dm-0): forced readonly [ 58.076601] BTRFS: error (device dm-0) in __btrfs_free_extent:6872: errno=-5 IO failure [ 58.085534] BTRFS: error (device dm-0) in btrfs_run_delayed_refs:2978: errno=-5 IO failure then in messages log I found many of these Quote BTRFS error (device dm-0): BTRFS: dm-0 failed to repair parent transid verify failure on 7833087508480, mirror = 2 2020-06-19T02:00:07+01:00 Servidor kernel: [50922.132991] parent transid verify failed on 7833087508480 wanted 9200 found 9148 2020-06-19T02:00:07+01:00 Servidor kernel: [50922.132993] parent transid verify failed on 7833087508480 wanted 9200 found 9148 I tried to do a btrfs --repair but it didn't work and didn't took note of the error. now the server is shutdown and I have to decide what to do next This is a: DSM 6.2.2-24922 Update 4 - Loader version and model: JUN'S LOADER v1.03b - DS3615xs - Using custom extra.lzma: YES - Installation type: BAREMETAL - Intel Server Board S3200SH + Core2Duo E7500 Installed just 2 months ago with shr2 and 6x4tb drives dmesg messages2 Edited June 19, 2020 by Napalmd add photos Quote Link to comment Share on other sites More sharing options...

0 flyride Posted June 20, 2020 Share #6 Posted June 20, 2020 If your files are accessible read-only, I would not continue trying to repair the filesystem. BTRFS is designed to self-heal while running and if it can't, the underlying corruption probably can't reliably be removed. This is different than ext4 where the only way to correct a problem is through the administrative launch of e2fsck. I would save your files elsewhere, delete the btrfs volume, rebuild it, and copy your files back on. All BTRFS documentation recommend the same. 1 Quote Link to comment Share on other sites More sharing options...
0 Napalmd Posted June 21, 2020 Author Share #7 Posted June 21, 2020 I will do that, but in the meantime I tried to mount the volume in a ubuntu live following synology website instructions, but couldn't, it gave me error wrong fs type, bad option, bad superblock. so I rebooted again to synology. it mounted the volume in read only.

Question
Napalmd
Hi this happened yesterday and a reboot fixed the problem but today it didn't fix.
Volume appears in crash mode, and read only mode.
I logged in from ssh and looked at the logs, I saw this in dmesg after the reboot:
then in messages log I found many of these
I tried to do a btrfs --repair but it didn't work and didn't took note of the error. now the server is shutdown and I have to decide what to do next
This is a:
DSM 6.2.2-24922 Update 4
- Loader version and model: JUN'S LOADER v1.03b - DS3615xs
- Using custom extra.lzma: YES
- Installation type: BAREMETAL - Intel Server Board S3200SH + Core2Duo E7500
Installed just 2 months ago with shr2 and 6x4tb drives
dmesg messages2
