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/sda
n) 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 AFAIK.
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.
