I will start there and also change the fstab line to use /dev/sda
May be it's good you have one uniform way of addressing which is less confusing
If in the future you create a new or delete existing partition(s) before
the partition in question, its number (e.g. /dev/sdan
) will change for the system but leaving the old value in fstab, hence there would be mismatch again.
So you better try to correct the UUIDs as all other guys proposed.
By the way the partitions can have labels
and system can find them by labels only
It doesn't matter if their UUID or device name (e.g. /dev/sd(x,n
)) changes - the label remains the same and will change only by your action.
IIRC this is the old-polack
's favourite way of partition addressing.
