Strange problem with ceph 17 pool. The pool has been deleted. The residual information affects the PGS distribution balance.

Pve 8.2 Ceph 17.2.7. Updated to the latest package.

Weird problem.

ceph osd lspools
shows:
1 .mgr
5 vmserver
6 server

I created a new pool, but I didn't think it was necessary, so I del'd it.

After using ceph osd lspools, it still shows:
1 .mgr
5 vmserver
6 server

But when I want to do pgs balancing, strange things happen now.

I first used:
osdmaptool om --upmap out.txt --upmap-max 400 --upmap-deviation 1 --upmap-active

Then I opened the file and found the ID of the pool that was del. < ceph osd pg-upmap-items 15 >

ceph osd pg-upmap-items 5.35 18 20
ceph osd pg-upmap-items 5.3c 22 19

Please ask the experts, how to eliminate this strange problem? Is it a pve problem? Can't clean up the residual information?
