If you set min_size to 2 or more, it will disable reads and writes to the pool by blocking requests. Min_size is the minimum copies of a PG that need to be online to allow it to the data. If you only have 1 copy, then it will prevent io. It's not a flag you can set on the pool, but it should work out. If you have size=3, then min_size=3 should block most io until the pool is almost fully backfilled.

Hello,
we have one pool, in which about 10 disks failed last week (fortunately
mostly sequentially), which now has now some pgs that are only left on
one disk.
Is there a command to set one pool into "read-only" mode or even
"recovery io-only" mode so that the only thing same is doing is
recovering and no client i/o will disturb that process?
Best,
Nico
