Don't forget to have a maintenance program - run a scrub regularly once |
32 |
a week or so - I have enough btrfs drives (22 qemu files, 4 WD Greens |
33 |
att) to see about one or two scrub fixable errors a week with no obvious |
34 |
cause, sometimes serious (in a critical file). My experience is that if |
35 |
you ignore these errors they seem to increase over time resulting in a |
36 |
crash and burn. Keep an eye on your logs as btrfs will list the errors |
37 |
there as well ("grep -i btrfs /var/log/messages"). For the ones scrub |
38 |
cant fix, delete the file and restore from backup. Errors that require |
39 |
off-line fixing (btrfsck) are the ones where I have lost file systems - |
40 |
though I have not seen this in the last 6 months. |

I am quite practised in restoring from backups because of btrfs :) |
