lost swap and он не разрабатывает why

гm running an Ubuntu 14.04 LTS on в DELL Inspiron 7. I was happily browsing away, when all of в sudden the laptop turned off эксперт if someone unplugged the power. I reboot не problem, but I noticed, that I have lost my swap partition. It turned out the UUID changed. I have of course не разрабатывает when the swap was lost, but I haven't messed around with the partitions since install, so it is very-very unlikely it was я (unless в program I installed did something funny...). I would be interested if anybody - any идея, what could have happened.

Схвати в small надбавку info, the fstab says swap was on /dev/sda3 during install, now it's sda5.

EDIT:

Sorry, I was not exactly clear, I was able to solve the problem, I checked the UUID of the swap with blkid and changed it in fstab, and turned it on with swapon I was interested in if you have any разрабатываешь why it happened. I found out the problem when I saw that therВs не swap and swapon reported that it can't find the given UUID.

гll удар в лунку the outputs here none the less, but they already шоу I fixed the problem itself. But I have не разрабатывает what caused it :(
