Subject: read time tree block corruption detected
Date: Sun, 29 Dec 2019 12:43:57 -0800 [thread overview]
Message-ID: <CAOB=O_jxu5JOe=JiYVW_VZ1rgs9+mdHpAHkscXkc4MVRLrBKDw@mail.gmail.com> (raw)
On a system where I've been tinkering with linux-next for years, my /
has got some errors. When migrating from 5.1 to 5.2, I saw these
errors, but just ignored them and went back to 5.1, and continued my
tinkering. Over the holidays, I decided to try to upgrade the kernel,
saw the errors again, and decided to look into them, finding the
tree-checker page on the kernel docs, and am writing this e-mail.
My / does not contain anything sensitive or important, as /home and
/usr/src are both subvolumes on a separate larger drive.
btrfs fi show:
Label: none uuid: 815266d6-a8b9-4f63-a593-02fde178263f
Total devices 2 FS bytes used 93.81GiB
devid 1 size 115.12GiB used 115.11GiB path /dev/nvme0n1p2
devid 3 size 115.12GiB used 115.11GiB path /dev/sda3
Label: none uuid: 4bd97711-b63c-40cb-bfa5-aa9c2868cf98
Total devices 1 FS bytes used 536.48GiB
devid 1 size 834.63GiB used 833.59GiB path /dev/sda5
Booting a more recent kernel, I get spammed with:
[ 8.243899] BTRFS critical (device nvme0n1p2): corrupt leaf: root=5
block=303629811712 slot=30 ino=5380870, invalid inode generation: has
13221446351398931016 expect [0, 2997884]
[ 8.243902] BTRFS error (device nvme0n1p2): block=303629811712 read
time tree block corruption detected
There are 6 corrupted inodes:
cat dmesg.foo | grep "BTRFS critical" | sed -re
's:.*block=([0-9]*).*ino=([0-9]+).*:\1 \2:' | sort | uniq
303629811712 5380870
303712501760 3277548
303861395456 5909140
304079065088 2228479
304573444096 3539224
305039556608 1442149
and they all have the same value for the inode generation. Before I
reboot into a livecd and btrfs check --repair, is there anything
interesting that a snapshot of the state would show? I have 800gb
unpartitioned on the nvme, so backing up before is already in the
plans, and I could just as easily grab an image of the partitions
while I'm at it.
