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
(PostgreSQL 9.6.2 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 5.3.1-14ubuntu2) 5.3.1 20160413, 64-bit)
Thank you for your suggestions
