Hello,
Should it really be this way?
What happened was:
- a device (sdg1) was added as a write-mostly member to a degraded two-member RAID1 (md3) and started recovering;
- then it had some I/O errors;
- the filesystem on top of md3 got hit by those errors (see lines by "btrfs" below);
- this is despite still having perfectly working and readable mirror sdf1 in the array (!!!);
- shouldn't the reads have been quietly satisfied my md3 from sdf1, instead of just passing the buck^W error
due to unreadable sdg1 to the higher (filesystem) layer?
Complete dmesg follows:
