swap partition lost during the upgrade to 11.4

[Andrej Zupan]

During the upgrade from 10.10 to 11.4 swap partition was lost, because devices were renamed.

In /etc/fstab was

/dev/mapper/isw_dehfcahgdd_Volume06 none swap sw 0 0

instead of

/dev/mapper/isw_dehfcahgdd_Volume0p6 none swap sw 0 0

I'm running Ubuntu on dual boot machine together with Windows 7. Windows 7 uses additional partition hosting D: disk. Ubuntu and its swap space were in separate primary partitions. There was some empty space between D: disk and swap space.

I can't provide more information about partitions at the time of the upgrade, because I've rearranged them in the meantime.

I don't know... they all seem related somehow.

After I've fixed /etc/fstab, "Hibernate" appeared in system menu, but
it still doesn't work. I made swapoff, mkswap, swapon on swap volume. No
errors were reported.

After Hibernate command something is seemingly written in swap space
(accorting to fstab from LiveCd boot). After booting, something is read
from HD, yet Ubuntu goes into Logon instead of restoring anything. I
haven't found nothing special in logs.

My machine came with preinstalled Windows 7. I've immediatelly
rearranged partitions, and installed Ubuntu. After upgrade to 11.4, I've
rearranged partitions again and installed Mint. Mint's hibernation
works.

Probably unrelated: I can't reinstall grub from LiveCD.
