Hello postgres folks,
We're tossing around the idea of upgrading a replicated postgres cluster
(37 dbs) by breaking the replication, adding different size (larger) data
disks to the hot-spare, then turning replication back on, letting it fully
populate, then breaking replication, making the standby the primary,
upgrade the disks on the other system, bring it back up, replicate
backwards until fully replicated then failing-back to the original
primary. Is this feasible?
Our current size is 22 tb, and it is 97% full

Thank you for your suggestions
Can we correctly infer that you aren't using LVM? (Or in there no more room
on the rack/controller for new drives?)
