Hi all,
due an very silly approach, I removed the cache tier of an filled EC pool.
After recreate the pool and connect with the EC pool I don't see any content.
How can I see the rbd_data and other files through the new ssd cache tier?
I think, that I must recreate the rbd_directory (and fill
I don't know why you're mucking about manually with the rbd directory;
the rbd tool and rados handle cache pools correctly as far as I know.

You shouldn't rely on rados ls when working with cache pools. It
doesn't behave properly and is a silly operation to run against a pool
of any size even when it does. :)
More specifically, rados ls is invoking the pgls operation. Normal
read/write ops will go query the backing store for objects

That's true, but the rados tool should be able to manipulate binary data
more easily. It should probably
Hi Greg,
ok!
It's looks like, that my problem is more setomapval-related...
I must o something like
rados -p ssd-archiv setomapval rbd_directory name_vm-409-disk-2
\0x0f\0x00\0x00\0x002cfc7ce74b0dc51
but rados setomapval don't use the hexvalues - instead of this I got
rados -p ssd-archiv
