### btrfs scrub
|
||||
As a copy-on-write (COW) filesystem btrfs can compensate some errors from the underlying storage
|
||||
|
||||
##### systemd handling
|
||||
create for all btrfs filesystems a regulary scrub timer.
|
||||
```bash
|
||||
for p in $(lsblk -nflo FSTYPE,MOUNTPOINT | awk '$1=="btrfs"{print $2}'); do systemctl enable --now "btrfs-scrub@$(systemd-escape -p "$p").timer"; systemctl start "btrfs-scrub@$(systemd-escape -p "$p").service"; done
|
||||
```
|
||||
the manual way of creating is eating the correct escape.

### ATA/SMART
|
||||
#### hdparm
|
||||
