I'm new around here and I'm not sure if this is the right place to post. I was recently asked to bring in a used server from another site of ours. On booting, I found that it has been encrypted using LUKS. No one (either at our Head Office or the site in question) knows the password and the sysadmin who was incharge has since quit.
To complicate matters, backups were never taken of the data in this server, so essentially I think I'm screwed. I googled around quite a bit and most of them seem to be saying that recovery isn't possible - as stated here.
Eventually, I stumbled upon this question in Superuser and according to that, I deleted the entry from crypttab from the troubleshoot mode and now it boots, but the data required is in the partition that is encrypted.
How do I recover my Data from the encrypted partition?
PS: I have backed all the other data, just in case.
Thanks in advance
