Pool going to Inactive

Hi

I have 6 nodes and i am using erasure coding (4+2p) pools for  iscsi and smb.

For metadata pools i am using replicated pools of size 3.

After deleting shutting down 2 nodes some of the pool are going to inactive state, so i can't access iscsi and smb.

Pools details

which 2 nodes were deleted ? any of the first 3 nodes were deleted (management ) or 4-5 (storage) ? did you delete the disks in the deleted nodes before deleting the nodes or are they still available ? what is output command of ceph status ?

I didn't shutdown the first 3 nodes .

I shutdown the node 5 and 6

Didn't removed the disk , i just shutdown the 2 nodes to check the erasure code of 4+2 p and replication of 3 .

So is it ok to shutdown 2 nodes in erasure coding 4+2p

lower the min size of ec pool from 5 to 4.

What about the replicated pool that is also going into inactive state

Issue resolved by editing min_size , Thanku

If this is a production system,  i would recommend you leave the min_size as original even if pool is inactive until until the recovery process rebuilds the lost replicas from the 2 nodes down. If this was a test, i would start up 1 of the 2 down nodes. If you do go for reducing min_size, this will solve the pool inactive but you have no redundancy and may cause issues like data inconsistency if OSD go up and down for any reason, since you are allowing data changes to occur without any redundancy.
