Description:
Core dumps When trying to copy a file to an external SMR HDD formatted with btrfs. The external drives have been working well up to now. It is only over the past couple of days that problems have arisen. The issue is repeatable, even after rebooting. Both external drives have the same issue. The internal drives are formatted with ext4 and do not exhibit issues. Additional info: * package version(s) Kernel: 5.19.7-arch1-1 * config and/or log files etc. Attached kernel messages from journal in kernel.txt Attached core dumped message from journal in core_dumped.txt Attached core dump (zst) * link to upstream bug report, if any Steps to reproduce: sudo mkdir /mnt/backup-drive /mnt/backup-drive2 sudo mount /dev/sde1 /mnt/backup-drive sudo mount /dev/sdf1 /mnt/backup-drive2 sudo cp /var/backup/full/data/202209* /mnt/backup-drive/ The above steps are specific to the specific machine in question. However, each file copied is ~1G, the target drives are not full: df -h yields: Filesystem Size Used Avail Use% Mounted on ... /dev/sde1 3.7T 2.4T 1.3T 66% /mnt/backup-drive /dev/sdf1 3.7T 2.8T 909G 76% /mnt/backup-drive2 |

Either way, seeing as you can reproduce it, it's probably best if you report this upstream to the kernel btrfs maintainers.
