Table does not exist even if there is one
I have MySQL master-slave replication setup in Amazon EC2. For the sake of resilience, I have set up LVM on RAID 10 array, on both master as well as slave. I have been using ec2-consistent-snapshot for some time now to take the snapshot from the slave instance.
So, I tried to create the disks from those snapshots and attach them to a new MySQL installation. Since the new installation would not recognise the LVM and RAID setup, I reactivated the LVM and RAID in the new instance using the following commands.
Scan the disks for RAID array members:
mdadm --examine --scan <comprising disks>
Reactivate the RAID array:
mdadm -A -s
Reactivate the lvm:
vgchange -ay
Since snapshotting took the backup of the ibdata and iblogfiles, I removed them for the fresh installation. MySQL would start normal.
Help me out of this

Removed ibdata1? You can* remove iblogfiles but not the ibdata1!!
They're system tablespaces storing tables, indexes, metadata, undologs....
*=> Removing iblogs is okay once you stop mysql but not while it's running!
Update: Removing iblogs is okay only after shutting down mysql with innodb_fast_shutdown disabled.
You might like to review this answer to understand what is wrong! You might want to do a restore from the snapshot may be.

Don't remove iblogs either -- unless you have made a clean shutdown withinnodb_fast_shutdownturned off. LVM is equivalent to a power failure.
