LVM Frozen After Deleting Block Device
-
So I accidentally deleted the block device (by using fdisk) that LVM was using. Now if I run an LVM command, like lvs, it just sits there, frozen. I tried using lvremove, vgremove and pvremove but each says that there is no associated device. I'm not sure how to get the association with LVM removed so that the LVM commands will work properly again. Thanks.

Have you tried using dmsetup info? If you use that you will get a "name" for the mapped block devices that LVM would be using. Once you have the DM name of the device that is frozen, you can use dmsetup remove to disconnect the block device. I did a Google search and that is what I found. Give that a try.

I tried that, it removed the device and I rebooted but lvs is still hanging
-
I don't suppose that this is of any help?

I saw that link too but there is no such file.
-
What distro are you using?

No additional ideas? I'm kind of stumped.
-
What about manually deleting everything bad out of /etc/lvm/cache/.cache
Don't worry, if you mess up that file it regenerates itself.
-
If you see UUID entries in the .cache file and don't know what they are, you can do two things:
Look up all UUIDs: ls -l /dev/disk/by-uuid
Or look up the UUID of a device as in this example: blkid /dev/sda1

Sweet, that worked!
Need to:
- Use LVM tools to remove the settings.
- Use dmsetup to remove the underlying devices.
- Manually delete the leftover lines in the cache.
No reboot even needed. Thanks!

Awesome. Glad that that worked.
