I posted this question on the Raspberry Pi forum but got no activity. If it is a dumb question or something else, please say so...
While not often, I do experience power outages which stop one of my Pis and then usually results in the USB stick having the "dirty bit" set.
I know how to fix this manually:
sudo dmesg |grep sda1 ==> this finds references to sda1 in the message log.
If I see that it has reported a dirty bit for sda1 then I do the following:
sudo umount /boot
sudo fsck -V /dev/sda1==> answer questions based on the following output:
fsck.fat 3.0.24 (2013-11-23) 0x25: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt. 1) Remove dirty bit 2) No action
I reply this:
Starting check/repair pass. Starting verification pass. Leaving filesystem unchanged. /dev/sda1: nn files, mmm/ooo clusters
sudo fsck -a /dev/sda1
However, I would like to automate this in a script which could be run manually or during boot up. Can anyone assist or point me to a good reference? Obviously, I may also want to do this for the SD card OS partition.
