Hello,
we have very important server running CentOS 5.3 with incredible
terabytes of valuable data stored in luks partition. Server was just
ok, but one hdd died in RAID-5, so I had to reboot, and didn't mention
this line in fstab:
LABEL=SWAP-sdc1 swap swap defaults 0 0
/dev/sdc1 is our encrypted drive.
after reboot 2gb of swap were added to /dev/sdc1
Sep 25 09:22:54 backup kernel: Adding 2097144k swap on /dev/sdc1.
Priority:-1 extents:1 across:2097144k
After removing swap from this drive I am totally unable to luksOpen
partition, though I know password is 100% correct.
cryptsetup luksOpen /dev/sdc1 crypt2
Enter LUKS passphrase:
Enter LUKS passphrase:
Enter LUKS passphrase:
Command failed: No key available with this passphrase.
LUKS header is at the beginning of drive.
cryptsetup isLuks /dev/sdc1 gives no error - so drive is luks
encrypted and recognized as one, but still cannot be opened.
cryptsetup luksDump /dev/sdc1

But i.e parted shows this:

Welcome to GNU Parted! Type 'help' to view a list of commands.

Partition Table: loop
Number Start End Size File system Flags
1 0.00kB 5990GB 5990GB linux-swap
linux-swap as fs and partition table now changed from gpt to loop.
Anyone knows how to fix this and remove this swap partition and fs
from this partition?
Sorry for my clumsy English, hope you got the main idea of the problem.
